A new photo of Sharpless 132 (Sh2-132)
I have shot this beautiful target in Cepheus several times with a different focal length instruments. This time I have shot it with my current setup build around Tokina AT-x 300mm f2.8 https://astroanarchy.blogspot.com/2020/01/the-frankenstein-monster-my-current.html

G65.3+5.7 , large supernova remnant in Cygnus, project continues
A large piece of an older mosaic image added, now the panorama covers sky from the Cresscent and Tulip Nebula all to wat to this large supernova remnant.
Previous version was with six frames and it can be seen here, https://astroanarchy.blogspot.com/2020/11/g65357-large-supernova-remnant-in.html
Here is a first single frame version of this SNR, https://astroanarchy.blogspot.com/2020/11/a-supernova-remnant-in-cygnus-g65357-snr.html
This is a rarely imaged target, this is also one of the most difficult targets, I have ever shot. Due to a very dense star field, large angular dimension and a very diffused structure this is much more difficult target, than a Simeis 147 supernova remnant in Taurus but just little easier than an other dim SNR in a same area of sky, the Cygnus Shell, W63.
Total exposure time of 60h was needed to have this image. The imaging system is very fast since it's undersampled and that's good when I want capture a very large, dim and diffused targets like this one. My current imaging system, https://astroanarchy.blogspot.com/2020/01/the-frankenstein-monster-my-current.html
G65.3+5.7 SNR has a large angular dimensions, than brighter and more famous supernova remnant in Cygnus, the Veil Nebula. The angular dimensions are about 3x4 degrees. This is a very difficult target, it has a very low surface brightness and the starfield is extremely dense in this part of the Milky Way.
NOTE, the "noise" in the photos is not a noise at all, it's glow from countless stars,

Sharpless 124 (Sh2-124)
I found unprocessed material from my HD! Back in January 2016 I shot data for the Sharpless object 124 in Northern Cygnus. Something must happen at the time since I never processed the data.
Sh2-124 is an emission nebula in northern Cygnus at about 8.500 light years away. It doesn’t seem to be imaged very often, and I was not able to find much additional information about it.

A supernova remnant G65.3+5.7 SNR in visual spectrum
I have published this image in mapped colors yesterday. This time the color channels from narrowband channels H-alpha, O-III and S-II are combined so, that result is very close what human eye might see, if it could be sensitive enough.
G65.3+5.7 SNR in constellation Cygnus has about the same angular dimensions, than brighter and more famous remnant in Cygnus, the Veil Nebula. The angular dimensions are about 3x4 degrees. This is a very difficult target it has a large angular dimensions, very low surface brightness and the starfield is extremely dense in this part of the Milky Way.

A separated photos of the light from an ionized hydrogen and sulfur (H-alpha & S-II) and the light from an ionized oxygen (O-III). There is a big difference between elements. Note, the bright star just up from the center is almost invisible at O-III light. it's there but very dim at light of an ionized oxygen.
INFO
SNR G65.3+5.7 was discovered by Gull et al. (1977) during an OIII survey of the Milky Way. Some parts of this SNR were already catalogued by Stewart Sharpless in his SH2 catalog as SH2-91, SH2-94 and SH2-96, but they were not recognized as being part of a bigger structure at that time. The idea that they could be part of a larger SNR was postulated by Sidney van den Bergh in 1960, but it took until 1977 for this to be confirmed.
This is one of the larger SNR in the sky spanning a region of roughly 4.0×3.3 degrees. Mavromatakis et al. (2002) determined the age of the SNR to be 20.000-25.000 years and the distance about 2.600 – 3.200 light years. The shell has a diameter of roughly 230 lightyears! This SNR is a predominantly OIII shell with also some H-alpha signal.

A supernova remnant in Cygnus, G65.3+5.7 SNR

The Tulip nebula in cygnus, Sh2-101
This is my second light photo for the cloudy Autumn season 2020. The area next to well known Tulip Nebula is very beautiful and less imaged due to its large size and relatively low surface brightness. My current toolset is very suitable for this kind of objects, since its kind of heavily undersampled and that's good when I need to capture very dim and large objects.

First light for the Autumn season 2020
First light for the season is always a big thing for me personally. I have had really bad troubles to have a imaging telescope. Lots of promises but nothing happens so i'm out of real tools. I do have a kind of working imaging platform built around an old Tokina AT-x 300mm f2.8 camera lens, here is some info about this toolset, https://astroanarchy.blogspot.com/2020/01/the-frankenstein-monster-my-current.html
I have an imaging plan but for the first light I selected something more "easy" to test my system after a six months pause due to nightless nights up here near to polar circle. A supernova remnant Veil Nebula in constellation cygnus is a beautiful and large target with some really dim parts and background nebulae.
I have shot the Veil nebula many times during the years with a different optical configurations and it's always shows something new and different, what a fascinating target!

INFO
Veil Nebula locates in a constellation Cygnus at distance of about 2400 ly. It's a cloud of ionized gas and dust, leftovers from an exploded star. The star went off some 5000-8000 years ago at distance of about 1470 light years. This, relatively faint target, is difficult to image due to the large angular diameter, about three degrees, and a dense star field. I have shot this target so many times over the years and i never get tired to it, ther is always something new to find in it, Here is a collection my photos from this fascinating target, https://astroanarchy.blogspot.com/search?q=Veil+nebula
