It seems to me that planetaries and clusters are well-suited to simple smartphone shots. Here are a few recent ones. Not as good as M27 a while ago (some are very small!) but fun to image them. In order: M76, (Little dumbbell), Caldwell 22 (blue snowball), NGC6826, NGC40. I also reprocessed my old M27 shot, stacking 4 shots and Photoshopping it a bit more on the phone (last shot). All taken with an ancient 8" SCT and a Samsung Galaxy S10.

I've tried to image this before, to no avail, but last night the imaging gods were on my side. This is a single shot, with minimal on-phone processing (I will stack and tweak more later, maybe). Amazing what these phones can do - even the pink/red shell is just coming tbrough. Meade LX200 8" SCT (circa 1992) plus Samsung Galaxy S10 in "Night mode" (about 20 s automated exposure).
Messier 57 is is just coming into a position for a decent look around 11 30 pm. IT is a colourful object and I thought it would give me a good target with which to practice my colour developing in PS/Lightroom. I have read so much about how to produce a LRGB image from the four stacked/calibrated luminance, red, blue and green images, a lot seems contradicatory and some, when followed, gave me colour yes, but not as we know it. I am sure a fair chunk must be put down to me. Anyway, I now have a work flow which gives me colour, sometimes resembling what other people have obtained. Progess of sorts.
This images is based on 114s subs at gain 139, offset 21.

Messier 57 Ring Nebula in Lyra
NASA: M57, or the Ring Nebula, is a planetary nebula, the glowing remains of a sun-like star. The tiny white dot in the centre of the nebula is the star’s hot core, called a white dwarf. M57 is about 2,000 light-years away in the constellation Lyra, and is best observed during August. Discovered by the French astronomer Antoine Darquier de Pellepoix in 1779, the Ring Nebula has an apparent magnitude of 8.8 and can be spotted with moderately sized telescopes.
Equipment: Celestron 9.25 XLT at F10, Skywatcher EQ6 Pro GEM, ZWO 1600MM Pro, ZWO EFW with ZWO LRGB filters, QHY5IIC guide camera on Skywatcher 9 x 50 finderscope, Celestron Focus Motor
Software: Ascom 6, Eqmod, Cartes du Ciel, AstroPhotography Tool, PHD2

Hi, i..m on Stargazers Lounge for long time ago, but now i have a new scope at last!!! The scope is a Skywatcher classic200p dobsonian, and i received it just one month ago. I.m really happy with it. For now, i.m using the stock eyepieces that come with the scope, a 25mm and 10mm super plossl 52. Yesterday i was received a Celestron Omni barlow, and that expands my magnification range. I posted some pics with my set.
Congratulations to Stargazers lounge team, this is one of the best sites to learn about astronomy and equipment.
Besf regards to everybody
