8-Burst, NGC2440 and Ghost of Jupiter PN's
SPX350 F9.1, ASI290 uncooled, Baader RGB Astronomik UHC filters.
NGC 2440 is a strange PN as its core is searingly bright but the wings are quite faint so it needed a good stretching. 0.38"/pixel
8-Burst nebula is always a beauty rgb arrangement seemed to work best. 0.38"/pixel.
The Ghost of J was also very bright needing 2 exposures shot at full resolution in good seeing. 0.19"/pixel.
The ASI290 at 20-30 degrees does not need dark frames at all it would seem which removes a hassle. There is a brighter bottom of the image when binned which can be removed with flats or gradient removal software.
These images are way better than my previous efforts which I though were pretty good.
Regards, John.
