CCD Imager Posted April 28, 2020 Share Posted April 28, 2020 (edited) This faint galaxy group high in Ursa Major is a struggle from a semi-rural site, i.e. my back garden, I totalled around 15 hours of data. Other astrophotographs show a predominantly blue galaxy except for the center, but using Astrodon true colour filters and APP's calibrate star colours, my version shows very little blue. C'est la vie! Taken with a SW Esprit 150mm and ASI 183 camera. With a pixel scale of 0.47 arc sec/pixel, high resolution imaging is possible with relatively small scopes. I do think this galaxy group is very attractive and infrequently photographed, so pleased to get something a bit dfferent.

carastro Posted April 28, 2020 Share Posted April 28, 2020 Lovely image, I have been trying to get this one, only tried once and the data was pretty poor. Carole Link to comment Share on other sites More sharing options...

silentrunning Posted April 29, 2020 Share Posted April 29, 2020 (edited) Excellent image especially as you point out obtained form a relatively small scope. Edited April 29, 2020 by silentrunning Typo Link to comment Share on other sites More sharing options...

Shibby Posted April 29, 2020 Share Posted April 29, 2020 Hi! There's a lot to love about this image. Really nice, fine detail showing off a great field of interesting galaxies. Perhaps your colour is the more genuine one? Link to comment Share on other sites More sharing options...

Tom OD Posted April 30, 2020 Share Posted April 30, 2020 Great result. There are a lot of Galaxies that respond very well to a small pixel camera and a 1m refractor. Tom 2 Link to comment Share on other sites More sharing options...

Yes, someone else posted a very blue version recently which looks fantastic but your version is probably much closer to reality. I enjoy seeing both versions but I wish more of the exaggerated images were labelled as such.

The astro imager, aka artist, can portray whatever he/she wishes. I do think that audiences are more wowed by high colour saturation driving this type of processing. 1 Link to comment Share on other sites More sharing options...
