Hi All,
On Tuesday we had some of the that rare 4/5 seeing and tranparency. Lucky for me the ATIK-2HS i bought from a fellow amarter (thanks Doug!) showed up the day before along with a set of new Astronomik type 2 LRGB filter and a holder. Monday was like Christmas only better. I set up my rig in the normal manner for webcam imaging and shot 2 avis for every color plus luminance. I didnt have much information in the way of proper protocol for settings and workflow, but i thought i did ok with it so far. This is the best Saturn image i have taken with my SV-102 apo. I used a 2.5x powermate stacked in a 2x barlow. I plan to purchase a 5x powermate real soon! One mistake i made during capture was to change the gain setting during the colored filter phase. So my color balance is off a bit. I tried hard to restore it with hue and saturation settings. This is the best i could do with it. I found out yesterday that you have to leave the gain settings the same for the colored filters, but changing the Lum is ok. The settings i used were 1/25 sec, 10fps, 50% bright (the gain i adjusted per filter as mentioned). I ran the final image thru Neat Image to clean it up a little too.
Like many i who have posted about this, i am a rank amature at RGB imaging. However this is a very exciting and im pleased with the results vs the ToUcam. For my small aperture, the extra sensitivty of the monochrome camera will give me better results than the ToUcam. I just need to learn how to do it right!
Thanks for looking
