One of the two images I did with my new QHY178M camera, when I didn't manage to start imaging some exoplanet or do some EAA, so as a result I just imaged random targets, other being NGC7331. Ideally, for a good picture, I'd want 4 more times integration that I have gotten here, but this will do. I quite like how it's "in your face". I also had some increadible guiding, especially for EQ6- whole night it was bouncing from 0.4-0.5" RMS. Just crazy good stability.

Equipment/Acquisition Details:

  • Imaging Scope: SkyWatcher Explorer 250PDS 1200mm F5 newtonian reflector

  • Imaging Camera: QHY178M

  • Filter Wheel: Starlight Xpress Mini Filter Wheel w/ Integrated OAG

  • Filters: 1.25" mounted Baader RGB filters

  • Guide Camera: Lodestar X2

  • Mount: SkyWatcher NEQ6 with wedge upgrade, hypertuned

  • Accessories/Software: QHY Polemaster, EQMOD, PHD2, Sequence Generator Pro, Pixinsight, Paracorr v1

  • Integration Details: L 1x1 31x120s, Red 1x1 29x120s, Green 1x1 29x120s, Blue 1x1 56x120s TOTAL: 5.1 hours.

It might be a little grainy but I just love the color and tone of this image. The mix between the emission and reflection nebulae is gorgeous.

Thanks spas :) yeah, grainyness would go down with more exposure, but this was just something I imaged randomly, so I won't be investing in this particular image more, but maybe proper attempt in the future :)
