This is Markarian's Chain shot from my back garden over three nights in late March. Probably the deepest single image I've taken in terms of integration time...which leaves me feeling my processing is not quite doing the data justice...maybe I'll come back to it.
In any case, this is an incredible part of space; looking away from our galaxy reveals countless others!
The crazy number of Lum subs took a whole day for APP to chug through and so I've resolved to lower the gain from unity going forwards to get more manageable sub lengths than 15 seconds!
L: 1050 (!) x 15s R: 92 x 60s G: 165 x 30s B 165 x 30s....total integration time 8.2 hours.
Captured using APT, stacked in APP and processed in Pixinsight.
Thanks for looking!

Any idea where I can find an M54 female to M60 male ring adapter? I need to order it online since there arent any astroshops where I live so I'd really appreciate if someone can link me to such an adapter.
Basically I have a TS Optics 2" Adapter with compression Ring for Skywatcher Newtonians, TSM54-2 and I need to use it for my celestron newtonian which has a 60mm drawtube so I'll need some sort of adapter.

Hi, I observed these during amateur astronomer meeting at Tähtikallio observatory (in Finland) with 36" f/3.5 Newtonian. Lovely weather, although sky wasnt as dark as usually due to hing moisture content in the air so I didnt try to observe more Hickson groups. Instead I sketched few globular cluster's and bright galaxies, all of them listed in the Messier catalog. M10 and M12 were really beautiful although they were really low near the horizon.
