Uranus and four of his moons; Ariel, Umbriel, Titania and Oberon
Hello,
Here is my best effort to date at recording Uranus and four of his moons; Ariel, Umbriel, Titania and Oberon taken through my Tak Mewlon 180 F12 with a WO x2.5 Barlow. The skies were very poor in terms of transparency, the local air being very dirty due to smoke particles from burning off local bush land and the jet stream was also fairly active over Brisbane. Transparency 3/5 and Seeing 5-6/10.
The final image is an LRGB of:
30 sub frames 20 sec each for Luminance data (Uranus and moons).
5 sub frames at 20 sec each for RGB data (Uranus only).
Sub-frames were aligned and combined in CCDStack then finished in CS3.
Brisbane, Qld, Australia, 27th August 2009, from 00:38am to 00:56am AEST (UT+10). Tak Mewlon 180 F12 with WO x2.5, 2” Barlow at an Efl 5400mm at F30 with SBIG ST7 ccd camera. FOV 4.5' x 3' at 0.34 arcsec/pixel
I have also included a single Raw frame, to show the quality of the data that contributed to the final image, as well as a “Context View” screen shot from SkyTools 3 Pro which simulates the view and conditions based on my equipment, exposure and sky conditions.
Thanks for looking!
Dennis

Reason: Reduced bloat of Uranus disc
A top effort indeed.
Dennis, just a thought, do you have Noise Ninja.
If you don't then check it out, it does a great job of noise reduction and is a plug in for Photo Shop.
