lux eterna Posted December 14, 2019 Share Posted December 14, 2019 Hi all, This is 6 hours (30 x 12 min), taken with my modded Nikon D7000 @iso200 and Astronomik 12 nm Ha 2" filter on Meade LX200-ACF with reducer (=1600 mm FL @ F8). Guided with NexGuide on HEQ5 Pro. The plan was to do a Ha O3 bicolour on this target, but the O3 may be a future thing due to weather conditions. I usually remove the stars during part of my processing workflow and put them back later on, but this time I think the nebulosity and dust came out best without them. I did however try to find out which stars belong to Melotte 15 and include only those, just to portrait the Melotte 15 without anything between it and us, but I could not find that info. Processed with DSS, Starnet and PS. Ragnar 6 Link to comment Share on other sites More sharing options...
Adreneline Posted December 14, 2019 Share Posted December 14, 2019 I really like starless images when it helps you to appreciate the structure of the nebula. Thanks for sharing. Adrian 1 Link to comment Share on other sites More sharing options...
GiorgioF Posted December 15, 2019 Share Posted December 15, 2019 Very nice and detailed starless version. Agree with you, some stars will complete it. As an open cluster I suppose will be difficult to say which star belong to mel15. Maybe an arbitrary choice based on your eye? 1 Link to comment Share on other sites More sharing options...
