I am soooo rusty (aka M81 & M82)

[vineyard]

Hello,

Here's 17h20 of M81 & M82 from February, taken with a range of filters (UHC, CLSCCD, 6nmHA, L1) with an ASI294MCPro.  I am so rusty on processing DSOs that I'm sure this processing could be way better, but hey ho.

Cheers,

Vin

I like the annotated image as well. What telescope lens did you use?

Thanks @happy-kat - its a TV102iis (f/8.6) but with a 0.79x reducer/flattener added.  My spacing isn't quite right & there is probably some tilt, but this was me just tinkering w mono-style processing (using Pixelmaths to combine different filters in different proportions) - I'll probably keep playing with saturation just to see what happens, but all told I'm thinking more about a switch to mono now.

Added a bit of GIMPification which I think improves it a bit & also inverted image just for kicks.

The inverted image looks like great desktop wallpaper potential
