NGC 6888 in the HOO palette, it's just 1 hour 10 minutes total exposure time thanks to the British weather Drizzled in Astro Pixel Processor then finished in PixInsight StellaMira 90 with 0.8 reducer/flattener Antlia golden dual band 5nm filter Altair Astro Hypercam 26C Camera Ioptron CEM40G equatorial mount

I have been using the Altair 26C for around 6 months now and have noted a few keys areas. Good points Great build quality and it's light, drivers very stable, powerful cooling, built in dew heater, good warranty/support. Bad points While it does support usb2 (occasional corrupt data) I find it works flawlessly with usb3, no tilt adjust. Now the big question is would I buy it again, yes definitely but probably mono. Hope this helps Gary

Hi Ray I had a quick play with your data, the main issue is the very strong light pollution causing a strong gradient across the image, did you use a light pollution filter?.

Looks about right to me, maybe a bit of camera tilt but it's minor

The North American and Pelican nebulas' in the HOO palette, 45x5 min subs. Drizzled in Astro Pixel Processor then finished in PixInsight StellaMira 90 with 0.8 reducer/flattener Antlia golden dual band 5nm filter Altair Astro Hypercam 26C Camera Ioptron CEM40G equatorial mount

First light with my new SM 90 using the 0.8 reducer, Antlia 5nm filter and Hypercam 26C camera, I still have to tweak both my back focus and camera tilt but very happy with my first results. 40X5 minute subs

Very nice shot, how are you finding the new scope?.

Beautiful shot, it's unusual to such a wide field image of the Elephant Trunk.
