Alright, my first contact with light pollution... i was able to rescue the picture to a certain extent. Level adjustment was made with cinepaint 0.24, basically a GIMP offspring that can deal with floating point and 16 bit TIFFs. It can even work with FITS, but it has some file export issues--
alynwallace posted a topic in Getting Started Equipment Help and AdviceHi guys, Bit of a lurker here but time for a first post as I've scoured every corner of the internet and cannot find the exact info I'm after. My style of shooting is more landscape astrophotography over deep space and I really want to be able to photograph Orion using a wide angle lens (eg. Samyang 24mm) on either a Canon 6D or a Sony A7SII and pick up the nebulosity. I have a tracking mount (Star Adventurer Mini) and am familiar with stacking images. I was wondering if a light pollution filter would help my cause here as I've read they can help boost nebulosity. Started to get my head in a twist with all the various filters and different types of nebulosity. I really don't want to modify either camera as I use them both for daytime landscape work too. The Samyang 24mm has a 77mm thread on the front, would something like a Hoya Red Intensifier be beneficial to my aims? Is there a better front threaded filter available for what I want? Or is a clip-in filter better? Any help much appreciated, Alyn
Hi all, I've just bought a Samyang 14mm f/2.4 for my Nikon D5100 and am not happy with the results. I've already sent one back and now the replacement appears to be just as bad. As you can see in the sample there is quite a difference in quality. The images were taken at a fairly dark area, ISO400 for 30secs on a Star Adventurer. The crop is from the centre of the lens. Image quality only started to improve after stopping down to f/7.1. If the aberrations are this bad at wide open it would effectively be a useless lens. My kit 18-55 zoom gives far sharper stars across the aperture range. Am I expecting too much from the Samyang or should this one be winging its way back too? I appreciate any advice cheers
