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.
These are my last images of 2019 taken with my ED72 and 183mm pro to be replaced by a 533pro
These targets are not easy due to location trees etc except M1 , there was a bright moon as well so are all lucky shots
but at last i have taken them warts and all . My guiding was all off as well
Anyway a merry Christmas to you all and a Happy new year

My first image of M76 A bit rushed as clear nights are a rarity now
30x120s Bin 2 Luminance ,SW 102 , ZWO 183MM Pro , OVL field flattener ,guided , processed in Gimp
Took some Ha as well but poor results for some reason
Seems an Oiii filter may have brought out some more detail
i know its not great but just chuffed to have imaged it
The weather has been so bad I have had the time to finish a video on using astro filters with the Nikon Z bodies and Nikon camera lenses. There is a manual alternative to the FTZ allowing 1.25 inch filters to be fitted between camera and F-mount lenses, and for some lenses and end of lens solution make sense. FAstroTZ is described here:
