Hello,
Ever since seeing (Scott) Tornado33’s hi-res version
here, I have been meaning to have a look at this little beauty.
So, here is another test image from my system tuning adventures, of the Saturn Nebula aka NGC 7009, a Planetary Nebula in Aquarius at magnitude 8.3, size 28" laying some 3200 light years away. The central star has a magnitude of 12.8.
Tak Mewlon 180 F12 with x0.8 Reducer giving F9.6 (1728mm), taken with an ST7.
This is a single 10 minute exposure. The cloud rolled in as I was taking Darks so unfortunately, that was the extent of my testing for the night. When the clouds rolled in, I spat the dummy and in a fit of pique, forgot to take Flats, so I’ve had to perform a heavy amount of (unsophisticated) post processing in an attempt to make up for the temper tantrum!
The good news is that I am now getting better stars with my side-by-side guiding set up, at least on this one example! LOL!
Cheers
Dennis
