The comet, still in Andromeda, is now a little brighter than when I imaged it on 29 Feb, and despite it being low in a murky sky, quite a long tail is visible to the camera. As mentioned with the previous photo, its sky location means I can't view or image it with my 'scope.

Greetings from Norfolk! Hope you don't mind me posting an occasional image here. This is the first time I have got my 4" celestron up and running. This is a stack of 5x30 sec frames combined with deepskystacker. All taken at ISO3200 using an Nikon D90 at prime focus. No bias or flat frames taken, so hot pixels show up. Adjusted in photoshop. I realise just what a difference a dark sky makes!
It's pretty noisy, but there it is. The yellow markers identify the supernova in the galaxy M82. Pretty pleased to get this with a DSLR and zoom telephoto lens. The spiral galaxy M81 is in the upper right. I just wondered if I could catch it the first night following it's announcement.

This is a different processing of the original picture (www.flickr.com/photos/28153034@N07/16098908475/) which does not aim to make the sky so dark thus making dim nebulae like the Horse-head Nebula more visible.

On a personal note, I'm particularly proud of this photo since it's my first with my new mount (EQ-6), shot from my balcony through loads of light pollution and since my balcony faces south, with a poor polar alignment :)
Trying 300 lights stacked with 100 darks and bias files. Shot using ISO 6400. Noise was cleaned up a lot, but I think I might be reaching a ceiling without using a tracking mount. I'm not saying this is the best you will get untracked, I've seen better work come out of others. But my problems are:
1) I want to shoot this galaxy with a longer lens. Something like a 400 5.6 or my 150-500 @ 500mm. To do this, I need to invest in a tracking mount.
2) Shooting 10 1 minute subs should give me a lot more data than 1000 1 second ones.
3) My HDD is hating me having to shoot so many subs, darks, and offsets.

The Andromeda Galaxy is a spiral galaxy approximately 2.5 million light-years from Earth in the constellation Andromeda. It is also known as Messier 31, M31, or NGC 224, and is often referred to as the Great Andromeda Nebula in older texts. Andromeda is the nearest spiral galaxy to the Milky Way, but not the closest galaxy overall. It gets its name from the area of the sky in which it appears, the Andromeda constellation, which was named after the mythological princess Andromeda.
Andromeda is the largest galaxy of the Local Group, which consists of the Andromeda Galaxy, the Milky Way, the Triangulum Galaxy, and about 30 other smaller galaxies. Although the largest, Andromeda may not be the most massive, as recent findings suggest that the Milky Way contains more dark matter and may be the most massive in the grouping. The 2006 observations by the Spitzer Space Telescope revealed that M31 contains one trillion (1012) stars, at least twice more than the number of stars in our own galaxy, which is estimated to be 200–400 billion. (en.wikipedia.org/wiki/Andromeda_Galaxy).
The image also includes the galaxies M32 (left) and M110 (below to the right).

NGC246 is an interesting planetary nebula in Cetus. I imaged it during two evenings on the 30th and 31st December 2021 from my location on Gozo / Malta.
Imaged through an 8 inch f/8 GSO RC on an EQ8. Camera was a modified Canon EOS 700D with cooling, which kept the sensor at -15 degree Celsius. I used again the Optolong L-eNhance filter. In all 51 x 5 minute exposures were stacked with DeepSkyStacker in sigma clipping mode (dark, flats and bias correction applied). Further processing was done in multiple software like Fitswork (gradient removal), Photoshop (a slight correction of elongated stars, RGB alignment due to atmospheric dispersion, background neutralisation), Affinity Photo (saturation, contrast, levels, noise reduction).
North is to the right, in the top right corner you can also see NGC255,

Canon 5D3 with Celestron CGEM 1100HD. ISO 1600, 10 minute exposures with dark frame for each. Stack of 8 shots over two nights using Deepskystacker.
Manual guiding using Celestron's off-axis guider and Orion's 12.5mm illuminated reticle eyepiece.
For northern Wisconsin, this is very low in the sky (just above the tree tops) and so suffers from atmospherics. The stars are bloated and we don't get as much detail in the columns and so forth. Still, a pretty good shot - better than the one I took with the CPC 800 and 550D camera. Surprisingly little noise for only 8 stacks.

You know some nights when everything goes right, and all you really
remember is the imaging? Yes? Then you also know the soul destroying,
life sucking nights where a long list of things that worked just fine
last time decide to conspire against you. Last night was the latter
option. I wont bore you with details, but I nearly packed up at 11pm and
went to bed.
Thankfully (almost) all the problems went away after I rebooted my
laptop, so I managed to get everything working, left it running for ~6
hours, and still went to bed smile.gif
Seeing wasnt great, a fair amount of vapour in the air, lit up by the
moon, but it was quite still in the sky, breeze free on the ground...
and bl__dy cold! Not "winter" cold, but autumn has definitely arrived
with the fresh mornings leaving everything covered in dew.

Note: the lower right corner in the mid sized image shows some odd
curvature, which I pretty convinced is due to me overtightening the
front tube ring on the Borg and pinching the objective. Next time out, I
will have to keep an eye on that.
Image taken last night of 2019 Y4 (ATLAS) showing at least three segments broken apart. Fifty 60 second subs stacked in Deepskystacker,Gaussian sharpened in Fitswork4 and finished in PS CS2. Camera used was a SX Trius 825 mono binned 2x2 attached to C9.25 @ f/10 riding on CEM60.
My first ever try on this too..
Not good picture, but I got something out of it. It was difficult to find, because there wasnt any bright star near to see throug cameras finder.

I've never really done the Darks/Flats/Bias thing before. I've always gotten an image (like you see on the left) and used curves to lower the background brightness, assuming it was Light Pollution. In my recent LP reduction initiative, I thought I'd give Dark/Flats/Bias a solid effort to see how much of the background photons were due to my optics/CCD: Turns out A LOT!
This is a comparison of using DeepSkyStacker to stack just Light frames (on the left) vs stacking Lights+Darks+Flats+Bias frames (on the right). These are then leveled in DSS, but otherwise unprocessed. Quite a dramatic difference! I've dabbled with Flats earlier, but mostly did it wrong. I guess I'll be acquiring Darks/Flats/Bias from here on out! I"m really surprised how much "Light Pollution" is actually stray light in my optics!

Consegue contar quantas estrelas existem nessa foto? A visão longe da poluição luminosa é privilegiada. Se você nunca teve a oportunidade de ver um céu longe da cidade, procure fazê-lo. É magnífico a quantidade de estrelas que são vistas a olho nu. Quando se utiliza uma câmera então, os detalhes e as estrelas se multiplicam! Acho que essa foi minha melhor foto da Via Láctea até hoje. A estrela mais forte da foto na verdade é o planeta júpiter. Também é possível ver uma de suas luas e, abaixo dele, o planeta Saturno também bastante luminoso. Foto tirada dia 15/08/2020 em um céu Bortle 3/4.
Can you count how many stars there are in this picture? The view away from the light polution it's great. If you never had the chance to see a sky away from the city, I suggest you do it! It's awesome how many stars are visible to the naked eye. When seen through a camera lens, the details from the Milky Way and the stars are multiplied! I think this is my best picture of the Milky Way. The brighest star is in fact Jupiter. It's also possible to see one of its moons and, below, the planet Saturn, also very bright. Bortle 3/4 sky.
