Clear sky here last night so I took my camera to the outskirts of our city and pointed it in the direction of Orion for some shots. DeepSkyStacker used to stack 11 frames (f5.6 10 sec exposures at ISO 4000!)
Object Details: Having been in the midst of thunderstorms for the past several days, not to mention the nearly full moon at the moment; the peak of this year's Perseid meteor shower has been a bit of a non-event in this area.
Therefore, I made the time to take a first look at some wide-field Milky Way images I took while attending my 31st annual Stellafane astronomy convention (held during the first weekend of August in Springfield, Vt, USA (it's 84th year)).
Although I concentrated mainly on visual observing this year, and had the pleasure of viewing dozens of objects through some excellent large binocs & 20" class dobs that my friends had brought, I did setup a Star Adventurer tracking mount & Canon 700D (t5i) with an 18-55mm 'kit' lens and used APT and a laptop to take a series of automated exposures.
Upon examining the resulting images I found that Mother Nature had brought me a small present the morning of my birthday by allowing me to capture one frame showing two meteors running nearly parallel along the portion of the Milky Way known as the Summer Triangle!
Image Details: Taken from the scope field at Stellafane 2019 by Jay Edwards on the morning of August 2nd using a Canon 700D (t5i) and standard 18-55mm 'kit' lens riding on a Star Adventurer tracking mount, the attached is a single 2 minute exposure at ISO 1600 with the lens set to a focal length of 21mm and an aperture of f/4.
As presented here, it has been calibrated with darks & bias frames (but not flats), was processed in a combination of DSS, PI & PSP, is shown uncropped, has been re-sized down to 2X HD resolution and the bit depth lowered to 8 bits per channel.
Although the meteors will most likely get lost (averaged out) in the process, I'm hoping to have captured some additional images of this region of a sufficient quality in order to process a stacked image in an effort to improve the Milky Way's signal-to-noise ratio.
Taken through a borrowed Sigma 70-200 f/2.8, lightly cropped. Two 2-minute exposures stacked in DeepSkyStacker. If I had more time with the lens, I'd liked to have done an HDR set (so as not to burn out M42), but alas, condensation on the glass cut my imaging time short. I also didn't get a flat frame, which made processing difficult... once I brought out the Horsehead, the center of the picture was a bright orange blob. I tried synthesizing a flat in IRIS with no luck, and eventually just used a flat frame I took with one of my own lenses, which almost matches.

After seeing these excellent photos right next to each other in my contact photo list, and seeing a clear night sky for the first time in 2008, I thought I'd snag an Orion Nebula shot of my own. That's the Running Man nebula near the top.

It's an unremarkable photo as M42 shots go, but definitely one of my best.

I usually crop my images down more than this but, there is a few clusters towards the edges and to the far right is IC 417. I may reprocess it at a later date and crop it right down to the fly nebula.
The Fly nebula lies in the constellation of Auriga. It is an emission nebula and a reflection nebula. Sometimes referred to as a mini version of the Orion nebula, as it has a star cluster, including it's own version of the Trapezium. Some estimates have the nebula at about 7,000 light years from us.
Boring techie bit.

FINALLY got this image processed. Started gathering data for this project in early November 2020 but the weather has been so bad here in the UK, that I have given up trying to add further data to this image this. Only 6.6 hours total integration time sadly.
Quite happy with how it turned out though as I am still getting back into the hobby and learning all I can about post-processing. The dark arts are deep and mysterious in this hobby.
Comments welcome. Clear skies.

All i can find about this nebula is that it has number 289 in Lynd's Catalog of Bright nebulae. It is not bright at all and "Hidden" in a dense Milky way star field. In the middle of the field of view we can see an open star cluster with code DO45. The location is: RA 21h12m, DEC 37D00m.

Description:
This large, pretty and bright open cluster of stars - which happens to lie in our line of sight in front of one of the bright and star-dense arms of our Milky Way galaxy - is a favourite observational target of northern hemisphere astronomers on summer evenings.
From Wikipedia:
"The Wild Duck Cluster is one of the richest and most compact of the known open clusters, containing about 2900 stars. Its age has been estimated to about 250 million years. Its name derives from the brighter stars forming a triangle which could resemble a flying flock of ducks (or, from other angles, one swimming duck)."

This is my first attempt at photographing the
milky way. It's difficult as there are few clear
sky nights and I live in very light area. It's much
darker here in Seaton and there's a nice open
view over the sea.
It is 25 photos, lights, darks and bias, stacked
with DeepSkyStacker 5.1.3. Rather than using
the raw files, I used JPEGs to cope with barrel
distortion. Saved result to clipboard and then
used paint to create a JPEG. Squared, framed
and colour balance changed using my software.
Now the Moon has taken it's leave for a while, and Orion is showing himself at a reasonable hour, this is the next obvious target.

Explanation: The first hint of what will become of our Sun was discovered inadvertently in 1764. At that time, Charles Messier was compiling a list of diffuse objects not to be confused with comets. The 27th object on Messier's list, now known as M27 or the Dumbbell Nebula, is a planetary nebula, the type of nebula our Sun will produce when nuclear fusion stops in its core. M27 is one of the brightest planetary nebulae on the sky, and can be seen toward the constellation of the Fox (Vulpecula) with binoculars. It takes light about 1000 years to reach us from M27, shown here in colors emitted by hydrogen and oxygen. Understanding the physics and significance of M27 was well beyond 18th century science. Even today, many things remain mysterious about bipolar planetary nebula like M27, including the physical mechanism that expels a low-mass star's gaseous outer-envelope, leaving an X-ray hot white dwarf.

An attempt at capturing some of the Milky Way through some pretty bad light pollution. 24 light frames, 25 seconds each and some 20 darks. Stacked in DeepSkyStacker and edited more in Photoshop. Processing it all was... interesting, which I think shows in the image. It may look a bit too blotty and blown out in places for my liking but I'm done tweaking it for now!
You can see most of the constellation Cygnus in the lower part of the image with the star Deneb close to the middle of the frame.

I am not really sure if it was worth staying up and loosing all that sleep but here it is. I never saw the asteroid myself. But the strange thing is that is didnt show up on the last 7 frames. It might have gone behind some skies. But the other stars were there so I dont know..
Since there was different data on exactly when it was due I stayed up for 2 hrs and fired of 99 shots every 16 mins.
Anyone knows what happened to it after it passed M44? It dissapeared for me as you can see in the shot here. I have several frames where it just didnt appear.. Strange..

I wasn't going to process this because I had triple spikes around Alnitak following the addition of data from previous sessions and not realising that the camera wasn't aligned in the same way each time! Doh! So I cloned them out.
This looks more natural than my previous overprocessed/clinical efforts, although it needs shed loads more data of course, which I can't provide unguided. 1 hour 26 minutes in total.

Initial crude stacking of a set of 20x 1 minute exposures of M51 to show the Supernova that recently erupted. (Marked with black arrow, Approximate magnitude 14.5)
The supernova just looks like a small faint star, no brighter than most of the other faint stars in this image ... but keep in mind that it's in Galaxy M51, 31 Million light years away from us. The other faint stars are probably only thousands of light years away, and are within our own galaxy. The supernova could be 5000x further away!
Skywatcher Maksutov Newtonian telescope 190mm F5.3. LXD75 Mount. Canon T1i DSLR ISO800.
I took about 50 exposures mostly 1 minute each. Most of them are streaked too much to use even with my low standards, but I'm happy I was able to get some ok 1 minute shots, usually i can only do 30 seconds. I was setup on a cement patio tonight instead of in the grass which may have helped.
For this quick initial view I just had Deepsky Stacker use the 20 best exposures, I'll take a closer look at them in the next day or so and add dark and flat frames to help remove some of the noise and vignetting.
Orion Nebula in Orion - M42. 14 November 2010
Took this in a rush on 14 November 2010 after intending only to view it. The forecast was for fog but that didn't happen until much later. Quickly set up the camera, took 16 frames at 30 secs and 12 darks before the battery expired! Quick recharge and took 20 flats - processed in a hurry so that I could get to bed! Quite pleased with it really.

NGC 5907
Sometimes known as Knife Edge or Splinter galaxy.
It's a spiral galaxy that appears edge-on from our viewpoint here on Earth.
It can be found in the constellation of Draco about 50 million light years away, it's roughly about 150,000 light years from one end to the other. Making it about 50% wider than the Milky Way.
First discovered by William Herschel on the 5th of May 1788.
It's quite a faint object, so best viewed on a big screen.

While not coming anywhere near close to the grandeur of the M13 globular cluster, NGC 6229 is another 'glob' that can be found in the constellation of Hercules.
It's discovery is once again down to William Herschel. He discovered NGC 6229 on the 12th of May 1787.
235 Years ago now!
The cluster is approx 100,00 light years away from us. One theory of it's formation, is that it could be the left over stars from a dwarf galaxy that was absorbed by the Milky Way some time in the long distant past.
