9/6/2021 The Iris Nebula

I tried for this object Sunday night but dew was overwhelming. I tried again Monday night and what a difference a day makes. Dew was barely noticeable even by 11PM. The Iris Nebula (aka NGC 7023) is a reflection nebula in the constellation of Cepheus and one on the prettiest things in the sky as far as I’m concerned. Hard to imagine ever being completely done shooting this object. I shot my first image of this last year with my 11″ at f/1.9, this time I am shooting at f/6.3. This was made from 120 individual one minute exposures with a light pollution filter. After stacking all processing was in Photoshop. It’s called a reflection nebula but there is also dark nebula there (obviously) and an open star cluster (to provide the light to reflect). As always, click the image to see it full size.
