During the early hours of 8th December 2022, the almost Full Moon occulted the planet Mars.

I imaged it with a William Optics 70mm refractor, Celestron 3x Barlow, ZWO ASI120MC camera. I used my portable Skywatcher AZGTi mount because I wasn't sure if I'd get the egress from my permanent pier as there are trees in that direction. This image is a reprocess of the video showing the first part of egress; the time when Mars re-emerged from behind the Moon at 06:01 UT.

 

I shot a two thousand frame video and had to do two separate stacking processes on them, one for the Moon and one for Mars because they were moving so quickly relative to each other. I then processed the images in Lightroom and Fast Stone Image Viewer. I'm slightly astounded to have captured surface features on Mars with such a small refractor, but this amazing telescope often surprises me with how versatile it is! The Celestron 3x Barlow is excellent quality too, which really helped with this. This image is a crop from the original photo.

The little pinwheel galaxy in Ursa Major. A face on unbarred spiral galaxy some 40 million light years away.

First discovered on the 18th of March 1787 by William Herschel. It's 2 main spiral arms are predominantly blue, which suggests mostly young hot stars inhabit them.

Many fainter more distant galaxies can be spotted in the background.

Imaged from my light-polluted backyard in the Niagara Region. So many re-processes, I finally ended up with this. As always, more time under darker skies would help. I blended some 10 second exposures of the core in.

another winter classic and back in 2019 my first deep sky object i captured. it was a spontanious decision to shot it as other parts of the sky were covered with thin layers of clouds, but i have no regrets :) it shows the great orion nebula, the de mairans nebula and the running man nebula.

Continuing clear skies of the night of 14-15 April allowed me to image this lovely pair of contrasting galaxies in Coma Berenices.

 

M88, towards bottom right is a spiral galaxy lying some 50 - 60 million lightyears form earth. The spiralling arms are very regular and can be followed right to the core.

 

M91 is one of the faintest objects in Chares Messier's famous catalogue with an apparent magnitude of 11. In contrast to M88 M91 is a barred spiral galaxy and lies at a distance of about 63 million lightyears from us. It was discovered in 1781 by Messier. The galactic bar is very prominent and M91 is classified as an anaemic galaxy, having little star formation and gas compared with others of its type.

 

I have also tried to identify a few of the fainter galaxies in the shot namely NGC 4516, IC 3476 & IC 797.

These two relatively nearby spiral galaxies, M66 top and M65 bottom are relatively "close" at a distance of around 35 million light-years. Their different physical characteristics means they provide an attractive pair to observe and image.

 

Both are around 100,000 light years in diameter, similar in size to our own Milky Way galaxy. They are also gravitationally bound to each other.

 

They are visually strikingly different to each other. M65 is low in dust and gas and there is little star formation in it so it looks relatively bland in comparison to M66. There is however a prominent dust lane visible. M65 may have a central bar but because of its oblique angle to us that is hard to ascertain.

 

In contrast M66 is an intermediate spiral galaxy which shows signs of contortion due to strong gravitational interaction. It has, in stark contrast to M65, striking dust lanes and bright star clusters along its sweeping arms. These colourful arms with tell-tale pink areas of hydrogen gas emissions indicate the galaxy has a high rate of star formation.

 

Both galaxies are found in the constellation of Leo.

Ok so updated with image with core not blown, the rest of image is exactly the same ( I usually save my images as 16-bit TIFF before JPEG save), so this is an HDRish shot. I basically just copy/pasted the core area from 5 min stack in 16min stack, then used curves and Hue/saturation tools to match rest of image.

 

I think I've done about as much as i can do with this one.

 

I would have taken more images but camera batteries died (50D can use AA, so I need to get my NiMH charged up for next time.)

The Western Veil (NGC 6960) aka The Witch's Broom, Finger of God, Lacework Nebula or Filamentary Nebula. This is part of the Cygnus Loop which is a supernova remnant. The source supernova was a star 20 times more massive than the Sun, and it exploded between 10,000 and 20,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, and 36 times the area, of the full Moon). While previous distance estimates have ranged from 1200 to 5800 light-years, a recent determination of 2400 light-years is based on direct astrometric measurements. The Veil Nebula is expanding at a velocity of about 1.5 million kilometers per hour. (Wikipedia)

Notes: Its been a massive learning curve but I have finally got NINA astrophotography to work controlling pretty much everything. I am extremely impressed with this software. Furthermore my trusty old D3100 shutter was controlled by the software through the mount and using the file camera it was able to pick up the pictures just like connecting more expensive Nikons or Cannons to APT(or several other apps that I looked into but came to dead end with the D3100). I was able to bring up the schedule, load the Western Veil which was currently focused on in Stellarium, set the amount of subs I wanted, turn on dithering, then NINA just did its thing by attempting to find the object then correcting itself through plate solving. It even did a meridian flip and recentred the object afterwards. Watching it do its thing was a thing of beauty and is miles away from my original attempts at astrophotography using a AZ goto mount and a star chart.

 

Being completely up front, like everything in astrophotography you must take several steps backwards before taking a step forward. I have dabbled with NINA for a while but struggled to get to grips with it. I tried taking this same object a few weeks ago but did not have a good session. For some reason, the plate solving was not accurate enough and the object was only half was in frame. This is either because I hadn’t loaded my coordinates in PS2 or the file camera was picking the last picture instead of the current one. Looking back 52 Cygni is very bright star front and centre and it should have been obvious to me that something was not right.

 

Incidentally that same night, about 4-5 subs in my pictures suffered from dew, pretty much writing them off. I have since bought a cheap camping mat and Velcro to make a home-made dew shield. Handily the camping mat camp with a perfectly sized bit of elastic; I have cut up some cheap cycling shorts and used the elastic to block out any light from the bottom of the telescope. I am hoping this will also help with the dew. I have also made a dew shield for the guider.

 

I took a gamble on this picture as the weather forecast had me believe that it was going to be cloudy all night. Up until this session it had been predicting a clear night all week and it looked relatively clear when I looked out of the window before setting up. It then cloudy over but only for about an hour and a half which gave me time to make sure everything was set up properly. It then became clear, although seeing was bad, but this did improve over the course of the night. Thankfully, my gamble paid off and is point back in the battle between me and the weather, I have been done so many times with the forecast predicting clear skies but them not materialising.

 

I add this comment to the end of every one of my pictures but the amount of green being picked up in the Star Tools colour module is insane. I think the D3100 bayer filter is 2 green to every red and blue, it seems like its 10 greens to every red and blue. I hope the colour in this is OK however I had to bump the green bias correction right up and max out the cap green slider. I am slowly but surely saving up for a proper cooled camera which am sure will again take me several steps back before bringing me forward!

The Southern Pinwheel Galaxy ( Messier 83, NGC 5236 ) in the constellation Hydra - by Mike O'Day ( 500px.com/mikeoday )..Messier 83 is a relatively large and bright spiral galaxy visible from southern and mid latitudes. Clearly visible is the central bar with its bright central bulge as well as multiple dark dust lanes and areas of nebulosity in the sweeping arms. At a distance of 15 Million light years, the Southern Pinwheel Galaxy, whilst close in astronomical terms, is too far away and hence way too small for my backyard telescope to resolve individual star; so all of the stars that can be seen are in fact in the near foreground of the image and reside, like us, in the Milkyway Galaxy...Much harder to see are the multitudes of far more distant galaxies that look like tiny fuzzy stars in the image. The easiest of which are PGC 724536 and PGC 48132 that appear close together in the centre of the image just to the right of Messier 83. Both are edge on and look like tiny flying saucers...Details:..Skywatcher Quattro 10" f4 Newtonian. .Skywatcher AZ Eq6 GT Mount .Orion 80mm f5 guide scope and auto guider - PHD2. .Nikon D5300 (unmodified)...Hutech IDAS D1 filter, 14bit NEF, Long Exp.

A lovely clear night back in April allowed me to squeeze in (despite shortening nights) this LRGB image of this iconic triplet of galaxies in the constellation of Leo.

 

Two of the galaxies are found within Charles Messier's catalogue - M65 (right) & M66 (bottom). The third galaxy is to be found in the NGC catalogue as NGC 3628 - also known as the "Hamburger Galaxy"

 

This is a true group of interacting galaxies and lying at a distance of around 35 million lightyears from us.

 

Our viewpoint means we see these three systems tilted at different angles - NGC 3628 appears edge on (displaying lots of dust and a prominent dust lane.

 

M65 & M66 are inclined enough so that their spiral arms are visible.

 

What's more the three galaxies exhibit rather different characteristics.

 

M66 - A barred spiral and the largest and brightest shows a high rate of star formation - evident by the extensive red regions of glowing hydrogen gas. It also shows deformed drawn out spiral arms - evidence of the interactive gravitational forces within the group.

 

M65 - An, intermediate spiral, is poor in dust and star formation. It appears the least by affected by interactions showing a more or less classical spiral shape.

 

NGC 3628 is an unbarred spiral which we are seeing edge on. The galaxy is transacted by a broad band of dust which stretches along its outer edge hiding young stars in the galaxy's arms.
