Hey astro folk,
I have been an owner of an FS 106N for about six weeks now. My jobs turned incredibly busy at the same time and the weather was also pretty naff on nights off. Despite that I have tried my best. Here is the fruits of many short times on a project I have been planning for ..... well I never planned it until it was happening. Four frames - eye ball alignment, once I started I decided to pursue it. First mosaic, first proper FSQ image from this scope, first post on Astrobin....
The nights of 19/8, 20/8, 24/8, 27/8, 31/8, 8/9, 10/9, 14/9, 15/9..
FSQ 106N, Canon 60Da cooled DSLR , ISO 800/1000, mainly 300 sec exp. All in all about 11.5 hours with most of the time in the bottom two segments, Moon affected the top part more.
Thanks peeps, Placidus can you explain the tweak ? I am not particularly great at processing so any help appreciated
Delighted! The attached image shows before (left) and after (right) using PhotoShop. Press Ctrl-M to show the Curves dialogue. Slide the zero point (circled in red) to the right, until it is at the foothill of the histogram, as shown at bottom right. Job done.
Absolutely no meaningful data are lost if you do this. You are just removing "haze", not data.
We always do the three channels (R, G, B) separately, so as to remove any cast in the background. This removing of background (zero point) colour cast is a very important step before doing any other adjustments to colour or saturation.
(In GoodLook 64, the whole process is done with a single mouse click. New version coming out shortly.)
..and more like 10 weeks..and I haven't used it yet....
...yeah, a bit of extra contrast might look good too.
