Because the UK sky gods continue to smile upon me, here’s some more #SeestarS50 #Astrophotography
This is NGC 3631, a ‘small’ spiral galaxy seen face on. You can find it in Ursa Major, and it’s an absolute gem.
An hour of imaging here. Noise reduction by Seestar, black point and definition tweaks by iOS.

So just below M86 here is a wee smudge of pixels. They are vaguely pinkish (zoomed in here so the colour is an artefact).
Those pixels a PGC169281 a galaxy that is A) travelling away from us at 11% the speed of light & B) is 2 BILLION light years away!

Blows my mind. Photons travelled for 2+ BILLION YEARS & then got captured by an image sensor. When they set off, life round these parts was basically unicellular. Incredible. The most distant object I've ever seen.

Right then! For the first time this year basically I got a GOOD night of #Astronomy and #Astrophotography with the #SeestarS50. And it’s Galaxy Season. And I got the scope to do 20s subs with basically NO rejections. Truly the astronomy gods smiled upon me last night. So here’s a wee thread of the captured photons. For all bat two of these I watched the light come in as well. Old Skool me. 1/

M81 and M82, 277x10sec
M101, 394x10sec

Both stacked in Siril, edited in Siril, Graxpert and Gimp. I've tried using the denoising and background correction in Siril, but the results in Graxpert are still so much better.

35 minutes definitely isn't enough for the pinwheel galaxy (it took me much longer to get that 35 minute exposure). But I got a good photo of the #moon on my way home.
