Description

A few firsts for me with this one:-
1. First narrowband image, using a dedicated Mono camera, the amazing ZWO 1600MM Pro - thanks to jlangston_astro for allowing me to borrow it!
2. First processing of HOO - really enjoyed it! Big milestones: learning to use Masked Stretch and Pixel Math, both of which are a bit tough to get your head around, but well worthwhile.
3. First target using off-axis guiding. A bit of overkill for a small, wide refractor, but excellent training for bigger and narrower scopes in years to come.

All of the above were extremely worthwhile, I definitely feel like I'm growing as an astrophotographer, can't wait to get on to the next projects.
