alacant Posted February 24, 2018 Share Posted February 24, 2018 Hi everyone First effort with my long exposure galaxy killer (I wish) setup. 8 minute light frames was as long as the moon would allow. Disappointing. 2 hours and barely a hint of a spiral. Oh, and some horizontal stripes -bad flat frames? The barren skies of spring are gonna be frustrating challenging;) Positive note? Still to find a target without OAG stars, though I should not speak too soon. Early galaxy days. Do share your experiences. Cheers, clear skies and thanks for looking. 1200d @ ISO 800 Link to comment Share on other sites More sharing options...
spaceman_spiff Posted February 24, 2018 Share Posted February 24, 2018 That's a very decent image, I think you got more definition in the structure. I had about the same time on it (~2 hours) and this is what I got... Link to comment Share on other sites More sharing options...

spaceman_spiff Posted February 24, 2018 Share Posted February 24, 2018 Thanks, it's 2x drizzled so the original image is about the same scale as yours. The spiral structure just needs more exposure time, as you found out! Link to comment Share on other sites More sharing options...
alacant Posted February 27, 2018 Author Share Posted February 27, 2018 Here's an interesting comparison from this project. 20 x 3 minute frames using a 250mm f4.7. Original post above was with a 150mm f8, 2 hours in 8 minute frames; both 1200mm focal length. 2 hours with the 250mm is gonna be interesting...
