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.

Processing Software: Stacked in Deep Sky Stacker, edited in Star Tools.
Moon: 38% Waxing Crescent
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 bino’s)
Polar alignment worked much better; the error was less than 1” 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.

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 I’m not sure I’ll 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 ‘The Seven Sisters’.
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. I’m 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 I’m glad I did, I don’t 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 I’m actually quite happy with this even if it is only just over half an hour of exposures.

This image is showing my journey since I started astrophotography in 2018. We can see the planet Saturn and it’s beautiful rings tilting in upward direction with the time. On May 2025, the rings will directed to Earth as edge on and we can not see it. This phenomenon is happening due to 27 degrees tilt in Saturn’s axis and it’s happening every 15 years. Also, we can see the progress in my experience in capturing & processing. I hope you can enjoy it.

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.

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!

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!

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.

La cometa C/2022 E3 (ZTF) è stata scoperta dall’osservatorio astronomico di Monte Palomar il 2 marzo 2022 ed è di lungo periodo, stimato in 52000 anni. Viene chiamata anche "cometa di Neanderthal" perchè il suo ultimo avvicinamento al Sole, prima del 2023, risale probabilmente a quando la Terra era abitata dagli ominidi, in particolare proprio dall’uomo di Neanderthal.
Quest’anno il punto di minima distanza dal Sole (perielio) è stato raggiunto il 12 gennaio a 166 milioni di km e la minima distanza dalla Terra (perigeo) il 1° febbraio a 42 milioni di km.
Il 30 gennaio la cometa era posizionata nella costellazione del Drago, non lontana dalla Stella Polare. Il suo aspetto era quello di un piccolo batuffolo di luce osservabile almeno con un binocolo e sotto un cielo buio. Nell’immagine invece si vede chiaramente il punto più luminoso, chiamato anche "falso nucleo", parte della chioma verde e un accenno di coda verso il basso.
Le altre stelle appaiono a forma di scia a causa dell’elevato moto proprio della cometa durante il tempo degli scatti.

"M5 is, under extremely good conditions, just visible to the naked eye as a faint "star" near the star 5 Serpentis. Binoculars or small telescopes will identify the object as non-stellar while larger telescopes will show some individual stars, of which the brightest are of apparent magnitude 12.2."

All the tasks were done with very tiny adjustments, its easy to overcook this with so many processing steps.
Taken with a 10" Dobsonian telescope and ASI120MC camera. I shot a 1,000 frame video using SharpCap, manually tracking to keep the planet in view. I centred it using PIPP then stacked the best 40% of the 1,000 frames in AutoSkakkert! 3. Stacked image was first processed in Registax 6 to sharpen the wavelets, then the rest of the processing was in Lightroom and Fast Stone Image Viewer. For the moons I shot a 500 frame video at a higher exposure and then extracted the individual frames and used one of the few had didn't have motion blur to blend in with the planet.

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.

It was my late father who got me into astronomy with the Moon being one of his favourites. I vividly remember his pointing this out when showing me.
I've not really got into closeup Moon photography before so abit of a first for me. My sister and brother came to visit and stayed in their camper van. My brother in law Nick is interested in taking up the hobby at some point so we set up the equipment. When the Moon is so full you have to take pictures of the Moon.
I'm not sure I sold it very well because there was a lot of faffing about. I've not done it for a while, it was cold, I was using my rubbish laptop and the seeing was terrible.
Anyway, we managed to get some pic's and in the end it wasn't too bad.

A supernova remnant some 5000 light years out in space. As with the Cygnus Loop you can envision the central point where the star must have exploded pushing out the gas and dust; now many thousands of years later some parts of the shell are brighter than others and form this interesting jellyfish shape. Unlike Cygnus/the Veil what we can see here is almost all hydrogen/red. For this version I added two hours of HA narrowband capture, improving the contrast and detail of the nebula.

My major August project! About 5 hours' worth of 7 minute frames captured over three nights. This is also my first attempt at this object. It's quite magnificent - check out all those dust lanes! This version has stars removed to reveal the brilliant nebula.
The Pelican Nebula is an emission nebula located in the constellation Cygnus, which represents the Swan, near the bright star Deneb. The nebula was named for its resemblance to a pelican and is associated with the neighboring North America Nebula (NGC 7000).
The Pelican Nebula is one of several notable nebulae found in the area of the night sky with the Northern Cross. It is located around 1,800 light years away from the Solar System and is an active star forming region with a particularly active mix of star formation and evolving gas clouds.

Aspettando il doppio transito su Giove ho deciso prima di riprendere Saturno , che sarà in opposizione il 14 di questo mese.
Il risultato sembra buono con le bande e la divisione di Cassini ben visibili. Si nota anche un colore leggermente azzurro nell'emisfero sud del pianeta.
