This is my first LRGB, Ha picture with my new QHY9.
3 x 3 minutes each of LRGB plus 10 minutes of Ha 7nm.
Total 46 minutes of data.
Telescope 8" Newt f6, modified NEQ6 mount,
guided with TS9 OAG, PHD guiding & Lodestar, used Ezycap for capturing subframes.
No: flats, darks or dithering were used.
This the first time I processed an LRGB image - used PS CS5.
It was easier to process than a DSLR image.
Stacked in DSS.
Used an RCC corrector which needs further adjustment.
Just checked the secondary mirror -
it needs cleaning & is the cause of the dust doughnuts.
The primary mirror & rest of the optical chain is very clean.
Pic is slightly cropped because the Ha subframe wasn't perfectly aligned with the other frames.
All comments are welcome.
