Astrophotography – deep sky

NGC 7000 photos from Lichfield 3-6/11/2020

These are my photos of parts of NGC 7000 this week – the main problem I have is that my mono camera simply does not have the field of view to catch the whole nebula.

Both attempts at Hubble Palette – first image shows bottom of nebula & Cygnus Wall, and the second was attempt to get part of nebula further up – located around the star HD 199870. In the second image, I kept more of the green colour when using SCNR in PixInsight (first image 100% removal, second 50% green removal).

M33 from 27/10/2020 processed in PixInsight and Photoshop CS6

This is my first image stacked using PixInsight rather than DSS/Nebulosity – then DBE and LRGB combination (although this version only uses RGB as I hadn’t finished stacking luminence data at point on processing!). I then used Photoshop for curves, levels, a layer mask to bring out the galaxy a bit more, saturation, contrast, Gradient eXterminator and Astroflat Pro plug-ins and and a little bit of Hasta La Vista Green plug-in. The image below has now yet had noise removal or any further sharpening.

Pelican Nebula – narrowband

My second ever photo in narrowband – HA-OIII-SII.

On this occasion, I decided to photograph the Pelican Nebula……I used plate solving to get into the nebula but did not realise that this meant I was right in the middle of it and hence my image below (which is based around the star HD198896) does not show much of the well known edge of the nebula – still, it is a riot of colour!

SII – Red
Ha – Green
OIII – Blue
