NGC 7023 Iris Nebula with a DSLR


Recommended Posts

Hi all,

Not posted an image in this part of the forum before, so here goes...!

Two versions, one 2x2 binned and one unbinned - I like to do this with shots that have a relatively small central object to get an idea of the object and its surroundings too.

Details are:

• 5:08 hours of integration at ISO800 from 224x60s + 21x240s subs
• Bortle 4 sky, Moon at average 36% phase, 44° height
• Calibration: 25 flats, 25 dark flats, 50 darks
• Hardware: Sky-Watcher 130PDS scope (F5), Sky-Watcher NEQ6 mount, Canon EOS1000D DSLR camera with IR filter removed, Sky-Watcher 0.9x coma corrector, Datyson T7C guide camera, Angel Eyes 50mm guide scope
• Software: polar alignment with SharpCap Pro, guiding with PHD2, capture with Astrophotography Tool (APT), stacking with Deep Sky Stacker (DSS), post-processing with StarTools, Photoshop CS2, Affinity Photo and Topaz Denoise AI
 

Thanks!
Brendan

Thanks! When I say DSLR I mean with a telescope attached, obvs. :)

Yes, I understood that.  :)  I’m just thinking it looks more like an LRGB image from a cooled mono camera than from a DSLR. Maybe that’s just me.

I'll take that as a massive compliment, thank you. :)
