Hi Bert,
That a very nice shot. You have brought out the detail very nicely. The tarantula is a great object for this type of image. Would like to see lagoon too when it is back up.
Can you clarify - for O3 blue and O3 green have you used the same O3 image for both the blue and green channels or did you do something slightly different?
Also did you refocus between the O3 and the Ha imaging? Im presuming so because of the achromat.
Results are extremely sharp and the fridge seems to have worked a treat.
Well done,
David
