stevewanstall Posted April 19, 2018 Share Posted April 19, 2018 This is my first image with a Canon 500D, modified for astro. Seems to be a big improvement on my unmodded NikonD5300. I guess its not the best subject for increased sensitivity though. I think some of the tidal structures are showing? And this shows what else is present....

wimvb Posted April 19, 2018 Share Posted April 19, 2018 Lovely! Definitely a tidal stream there. it will show better when you get rid of the green background. Link to comment Share on other sites More sharing options...
Demonperformer Posted April 19, 2018 Share Posted April 19, 2018 Yes, will be very nice once you give it a dose of HLVG. Link to comment Share on other sites More sharing options...

stevewanstall Posted April 20, 2018 Author Share Posted April 20, 2018 This is the image after being treated with HLVG (Hasta La Vista Green - free plugin for Photoshop). ED80, 180s x 19, darks, flats and bias Link to comment Share on other sites More sharing options...
Xiga Posted April 20, 2018 Share Posted April 20, 2018 Very nice Stephen Quick word of advice if I may - the modification on the 500D will mainly only help with shooting emission nebulae (or anything that has a lot of Ha in it). For everything else, such as galaxies which are mostly broadband, then you would be better off using your D5300 rather than the 500D. The D5300 is a much more modern camera, with a much better sensor. It also has no antialiasing filter, which helps with sharpness. Also, if you dither aggressively between every frame it will greatly reduce the colour noise of the background. ps - I also have a D5300 (although mine is modded). It's a brilliant camera, and has arguably the best performing sensor in it's price range. Link to comment Share on other sites More sharing options...
stevewanstall Posted April 20, 2018 Author Share Posted April 20, 2018 That's really interesting to know. I haven't tried dithering before. I shall take your advice! Thank you. Link to comment Share on other sites More sharing options...
