Planetary alignment 2022 in hires.
In this period, in the early hours of the morning, it is possible to observe this spectacular astronomical phenomenon, the planets appear in the sky arranged exactly in order of distance from the Sun, a bit like in the classic book photos illustrating the solar system. Unfortunately, I have not been able to capture the elusive Mercury, but what you see are exactly as they appear now: Venus, imaged in the infrared and ultraviolet wavelengths to highlight the cloudy structures consisting mainly of sulfuric acid, Mars, still very far away (it will be in opposition in December) and with an apparent size of about 7.7 ", very small but already showing interesting details, it is possible to notice the polar cap and the region of Syrtis Major, Jupiter with its characteristic Big Red Spot and its dynamic atmosphere and Saturn, which this year shows a greater portion of the south pole, characterized by an azure / blue coloration and its wonderful system of rings and bands. A real spectacle, which however costs the "small" sacrifice of setting the alarm very early in the morning.

Taken with a ZWO ASI120MC camera, Celestron C8 telescope and Celestron CGEM mount.
Captured in SharpCap, processed in AutoStakkert and Lightroom.
Taken from Oxfordshire, UK with a Coronado PST, 2x Barlow and ASI120MC camera. Shot through thin cloud. A 1,000 frame video was captured using SharpCap and the best 25% of the frames were stacked using Autoskakkert! 3. Processing was done in Lighroom, Fast Stone Image Viewer, Photoshop CS2 and Focus Magic.
I was intending to shoot overlapping images of the entire solar disk, but unfortunately I currently have a problem with my laptop screen which made it extremely difficult to focus the telescope but also made it near impossible to see well enough to get the exposures right. I gave up but did manage to capture some nice prominences in the meantime.
A quick data grab between holes in the clouds.
The Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is a spiral galaxy in the constellation borders of Virgo and Corvus, being about 31.1 million light-years from our galaxy, within the local supercluster. It has a diameter of approximately 49,000 light-years, 0.3x times the size of the Milky Way. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its outer disk, which is viewed almost edge-on. The dark dust lane and the bulge give this galaxy the appearance of a sombrero hat.

Isn't this a beautiful part of the night sky?
My software (Stellarium) was insisting that both of these objects could fit within my field-of-view, given my camera and scope combination. While watching meteors this weekend, I gave it a try, and much to my delight the software was correct! So, here are both nebulae in the same image!
The Lagoon Nebula (left) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes.
The Trifid Nebula (right) is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum-Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means 'three-lobe'.

Ok I don't see the trident either but this open cluster in Ophiucus fit the bill when I went searching for a wide target last night. The young blue stars provide a different look from the mostly reddish nebulae rising later in Cygnus.

Taken from Oxfordshire, UK on the afternoon of 3rd April 2023. Because it was mid-afternoon when I started imaging, conditions were not great, but there was some nice activity visible on the Sun, and sunspot group AR13270 was looking lovely.
Taken with a William Optics 70mm refractor fitted with a Thousand Oaks glass solar filter. Camera was an ASI120MC fitted with a Baader Continuum filter, and shot through a Celestron 3x Barlow. A 1,000 frame video was captured using SharpCap, then the best 50% of the frames were stacked using Autostakkert! 3. I sharpened the image using Focus magic, then processed it in Lightroom. I adjusted the colour to get rid of the green cast from the continuum filter.
Aristoteles and Eudoxus: First Photo with the Celestron 8 EdgeHD.
I managed to see the moon against a bright blue sky this afternoon, and this is my first real photo with the new telescope. The photo isn't very good, but it promises better things to come.
These two craters form a distinctive pair, and catch the lunar morning light together. They are well-known friends to those of us who enjoy telescopic views of the Moon.
Aristoteles Crater is the upper member of the pair, and Eudoxus the lower. I will surely visit them under better observing conditions, and will have more to say of them at that time. For now, enjoy the view, and know that I am a happy boy.

IC 1396
IC 1396 ĆØ un ammasso aperto molto sparso associato a una vasta nebulosa diffusa, visibile nella costellazione boreale di Cefeo; si trova in un tratto di Via Lattea parzialmente oscurato da densi banchi di nebulose oscure, in una regione galattica ricca di polveri e gas neutri con associate stelle giovani e calde di colore blu.
Osservazione:
Ć facilmente individuabile la sua posizione, subito a sud della stella Ī¼ Cephei, una delle stelle piĆ¹ rosse che si conoscano; individuare perĆ² l'ammasso in sĆ© non ĆØ facile, perchĆ© ĆØ molto disperso e quasi si confonde con il campo stellare circostante.
CiĆ² che, nelle foto a lunga posa prese attraverso un telescopio, appare ben evidente, ĆØ il grande complesso nebuloso che circonda l'ammasso; il suo aspetto ĆØ rozzamente circolare e attraversato da numerose macchie scure, che ad un'analisi piĆ¹ attenta si rivelano essere dei globuli di Bok, ossia regioni della nebulosa particolarmente concentrate dove avviene la formazione di nuove stelle.
Si tratta dunque di una regione HII, e fa parte di un vasto sistema di nubi molecolari e associazioni OB chiamato Complesso nebuloso di Cefeo.
CuriositĆ :
Una particolare nebulosa oscura che si sovrappone all'oggetto, vdB 142, viene chiamata anche Proboscide d'Elefante.
IC 1396 dista dal Sole circa 3000 anni-luce.

Taken from Oxfordshire on 1st May 2023 with a William Optics 70mm refractor and ZWO ASI120MC camera fitted with a Powermate 5x Barlow.
The telescope was on an EQ5 Pro mount on a permanent pier, tracking at lunar rate. It was still twilight when I started imaging and I was also dealing with varying amounts of thin cloud. The Moon was 85% Waxing Gibbous.
A 2,000 frame video was captured using SharpCap and the best 25% of the frames were stacked using Autostakkert! 3. Processing was done in Lightroom and Fast Stone Image Viewer, plus a bit of sharpening in Focus Magic.
Also known as the Pleiades and Messier 45, are an open star cluster containing middle-aged, hot B-type stars in the north-west of the constellation Taurus. It is among the star clusters nearest to Earth, it is the nearest Messier object to Earth, and is the cluster most obvious to the naked eye in the night sky.
The cluster is dominated by hot blue and luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be left over material from the formation of the cluster, but are now considered likely to be an unrelated dust cloud in the interstellar medium through which the stars are currently passing.[Wikipedia]

Weather/Seeing:- Clear nights are extremely rare these days, the last real night was in September. These days I must settle for the possibility of a break in the clouds. There was a clear spell at the start of this night, most of which was me faffing around setting up and then having to wait for my laptop to do an update. Just as I started polar alignment the clouds rolled in and it started to rain. I hurriedly covered all the electrics, switched off, threw my jacket over the scope, came inside and watched The Martian. Soon after it finished I went back out and it started to clear. After an hour and a bit of shooting; the clouds rolled in again, started to spit and I hurriedly started to pack up. It was a false alarm with it soon clearing again but I was tired and had already begun winding down. An observatory would really help but Iām not sure Iāll ever get to that point.
Other Notes:- I had to call this the Seven Sisters. My Dad got me into astronomy and one of the lasting memories of growing up was him regularly pointing āThe Seven Sistersā.
With constant clouds all I can do to keep connected to this hobby is watch YouTube videos and read up on the theory. I watched a fantastic lecture by Robin Glover on exposure times and have been persuaded to cut down my sub lengths significantly. Iām sure the read noise in the D3100 is very large so decided on subs just under half a minute long. This lecture and a recent video from Trevor Jones (the AstroBackyard guy) also persuaded me to ditch the light pollution filter and Iām glad I did, I donāt think adding a filter to this picture would have made any difference.
Perhaps this needs more time to eek out some details and reduce the noise but Iām actually quite happy with this even if it is only just over half an hour of exposures.

About 12-13 million years old and about 7,500 light years from earth. Clusters NGC 869 and NGC 884 can be scene with the naked eye from a dark sky site and with cheap binoculars elsewhere, just use the second line in the W of Cassiopeia to point to the left, it will appear as 2 faint smudges. Also known as Caldwell 14.
According to Wikipedia these clusters are blue shifted which means we are getting closer to them.
There are a good variety of star colours in this region, hopefully I have processed it OK to demonstrate this.

Light Pollution and Location: - Bortle 7/8 in Davyhulme, Manchester. Different websites tell me different things about this. It all depends on the time of night and which way I am pointing. At this time of year, with all the Christmas lights it is pushing 8 and above.
Weather: - A good clear spell of about 5-6 hours, as always at this time of year things start to get damp relatively quickly. Still low pressure, we have not had a run of high pressure since September.
Notes: - I was having problems with my
cheap laptop, the connection to the Wi-Fi SD card kept cutting out and its slow, especially at plate solving. I have relatively good PC with usb3 port, lots of RAM and solid-state drive so I have decided to make the switch to that. To do this I have had to buy a 20-meter usb3 extender cable.
First light with new PC was 12th December, this was the first moonless clear night for months. To say I was underprepared was an understatement. I spent several hours installing the required software to get things going and had forgotten how much work was involved in this. Eventually I got everything going apart from the guide camera which needed a major Windows update that I did the following day. To add to my problems the piece of metal on my mount that works with the azimuth screws to go left and right was loose. Stupidly I ignored this and ploughed on, polar alignment was tough, in SharpCap it would just jump about from one extreme to the other. I also still had my light pollution filter out. It was not a successful night, I had eggy starts and unworkable gradients. Too much of an effort to fix in star tools. I have since made sure this metal bit is connected properly.
So, on the 20th December I was much more prepared. Having marvelled at the great conjunction from my loft I set about working, this time with guiding and with the light pollution filter. (I know most people would have been working on the planets, but I do not have the right view to able to get it, too many houses and trees are in the way; sometimes I am happy enough with my eyes and cheap binoās)
Polar alignment worked much better; the error was less than 1ā so that makes me happy! The plate solving was amazing, its instantaneous which is great. The Wi-Fi connection to the SD card remained and it seems to transfer the files a bit quicker too. The Wi-Fi/SD combination is still not perfect as there is a 20s wait between subs, but at least it works.
Going forward I am reverting to 400 ISO and perhaps 1-minute subs. I am still convinced by Robin Glovers lecture but the D3100 is so noisy, the jump from 400 to 800 seems too much. I would love to know the read noise calculations for this camera so I could be more precise with my exposure times. One day it will be side lined for a better camera.
On a personal note, in January, I should become a Dad for the first time, this should be fantastic but will probably mean less time for this hobby. Let us see what happens!

Decided to photograph the moon before switching to deep sky objects for the rest of the night. This photo has had the saturation increased to highlight the differences in the lunar soil, which are *barely* noticeable to the eye when viewed through larger telescopes (usually in Mare Serenitatis or Mare Imbrium for me, at least). Tan/orange indicates iron rich minerals, and blue indicates titanium rich minerals. Captured at 6pm on November 12th, 2021.

Taken with a one shot colour camera from Bortle 7 skies in Sydney Australia.
The image consists of 90 x 4 minute exposures that were stacked on the fly using SharpCap software, 90mm lens, ASI294MC camera, Optolong LP-Pro filter and Losmandy G11 GT mount.
So whilst the camera was left open for 6 hours, the stack is effectively only 4 minutes but with so many sub exposures it is virtually noise free. The mount was unguided during that time and any small deviations from each 4 minute sub exposure were managed by a slight repositioning of stars in the SharpCap software.
The Helix Nebula (also known as NGC 7293 or Caldwell 63) is a planetary nebula (PN) located in the constellation Aquarius. Discovered by Karl Ludwig Harding, probably before 1824, this object is one of the closest to the Earth of all the bright planetary nebulae.The distance, measured by the Gaia mission, is 655Ā±13 light-years.The Helix Nebula has sometimes been referred to as the "Eye of God" in pop culture, as well as the "Eye of Sauron".

My first monochrome image. A beautiful area of our Southern skies with lots of HA. There was a lot to learn and I could not eliminate all the gradients. Not sure the flats worked exactly as they should have and I am sure those with better PI skills could have sorted that out. There was quite a lot of vignetting on the RGB images that needed correcting with the flats and very little on the HA images. I was surprised by this as they are all 36mm filters (although the RGB are mounted) with a relatively small ASI 1600 sensor. Perhaps the F4 of the camera lens I used is to blame. Anxiously awaiting my Skywatcher Esprit 100 - looking forward to putting the new gear to good use and having access to a regular autofocus routine.

Saw that the moon was stupid bright when I was about to bring my deep sky rig in and decided to shoot it. Not that often we get a full/blue moon on Halloween. Captured at 1am on October 31st, 2020.

Look at all that dusty, gassy stuff! My first foray into deploying the Hubble Palette for astro images. This is basically where you use a physical narrowband filter (like my ZWO Duo Band filter, which shoots in Hydrogen Alpha and Oxygen wavelengths) and you use software mapping (PixInsight) to map the different gas wavelengths captured to the captured data. This reveals a lot more detail than the human eye and basic cameras can collect. I also removed the stars to show iff the nebula a little more.
Many thanks to @lukomatico for his excellent YouTube tutorial!
The Rosette Nebula spans a distance of about 100 lightyears across and is located 5,000 lightyears from Earth in the Monoceros constellation.

Happy to present my capture of the Orion Nebula, a star-forming region located approximately 1400 lightyears from Earth. The nebula measures about 24 lightyears across and appears to be situated at Theta Orionis, the middle star in the sword of Orion, just south of Orion's Belt. Enjoy!

The Bubble Nebula (NGC 7635) is emission nebula in Cassiopeia constellation. Its formed by a powerful solar wind of a Wolf-Rayet star. It is a young star that emits strong ultraviolet rays that energise the surrounding molecular gas clouds to form a shape like a bubble. The diameter of the bubble is around 3-5 light years @ distance of about 7100 light years.

Sharpcap for polar aligning.
This came out as well as can be expected for my small equipment. I started imaging at 9:30 PM and ended at 1 AM . I hate the Meridian Flip!! Took a while to sort out guiding after the flip. I think my polar align was slightly off as I did not even guide in dec at first but had to enable after flip.
Testing out the ZWO Duo Band filter again. Less than ideal conditions last night - clear skies but the humidity was through the roof - water everywhere (including pools of it on my laptop). I'll revisit with longer exposures next year.
