I’ve taken a shot at Messier 51 again. Compared to Messier 51 and first light for my Orion Optics 250mm rebuild from last year it is more successful:
Conditions were much better and my guiding is considerably better with <> 0.6 total rms. With careful processing I am able to extract detail at the limit of the scope and camera performance when seeing is good, as it was last night.
It’s a bad time of year to image as astronomical dark is very short (around 3.5 hrs now), but you can’t turn down the opportunity for a moonless clear night! With 1hr per RGB filter and 30min of Ha squeezed in the result is a detailed but noisy image.
