M3 first one back colour imaging
First one after finally (8 months) getting my QHY168C back from China – actually a replacement because they said they’d fixed the old one but hadn’t. New replacement which works fine.

Deeper version of M13
Decided to try 240s exposures in each of RGB this time instead of my usual 180s (chosen to balance detail and LP) and it seems to have worked well, especially since there only 5 subs of each colour. Much deeper into the fainter stars too.

M27 (NGC 6853) Dumbbell Nebula
Done this one quite few times now but this is the first time processing with Astro Pixel Processor. Good for gradients and light pollution but a little slow.

M3 (NGC 5272) RGB just a few exposures
Just a few exposures between gaps in the clouds. L not used because of dust on the filter.

M15
First proper imaging session of the season. New mount (EQ6-R) is guiding well with an RMS error of about 0.6″, Coma corrector is working well too. Stars are sharp right to the edges.
| Object ID | M15 (NGC 7078) |
| Details | 2018-09-08 Not very transparent and the remnants of twilight too. |
