Here are s0ome first attempts at Jupiter . I used Gstar ccd Monochrome camera.IR/uv filter The bigger images were done with 6 inch skywather refractor.I used Virtualdub to capture the frames Registax to stack.I am not sure a what distance to set the CCD camera to the eyepiece.I have to get the focus better.Tony.
For a first attempt that's very good indeed Tony. The image scale through the refractor is very good, and as you say, a little more attention to focus next time. You should get some great detail!
I got your email, sorry it took me a while to respond. I'll respond here instead.
The Baader set was generally fine, but I found that the red filter was quite low in transmission and made colour balance quite tricky. Even with full gain, the throughput on all filters seemed lower than it should've been.
When I upgraded to the Astronomiks, the high transmission was immediately noticeable and all channels were brighter. Colour balance was much easier and there was better depth to the data. With the astronomiks, the green channel is brightest, with blue being the dimmest.
As an example, I might have blue at 100% gain, red at 95% gain and green at 90% gain to get approx the same histogram for all channels.

Hello Mike when you are Talking about adjusting the gain.Are you adjusting the gain on your CCD Camera. Tony
Yep - the gain control of the camera, controlled from within IC Capture.
A value of 1023 is 100% gain.
I'm not sure on the controls of the G-Star, gain may be different but should effectively mean the same thing. It's amplifying the signal.
This something I've just learn't the Gstar Is Deepsky ccd as well So the Gain is turned up to MAX.to do Deepsky . So when doing the Planets I have to either turn it off or only use a slight Gain adjustment.This should make an image of the Planets with less signal noise etc.When I did my jupiter the other night I had the Gain Cranked up to Maximum which probably didn't help things.

When I get to doing a color image Do I put the UV/IR filter in front of the colore filters or do I place the color filters in front and fit the UV/IR filter on the camera behind the Color filters.Tony

http://www.astrodon.com/products/filters/e-series/. Now these filters are supposed to be a step above Astronomik filters.there is some good info on the here . Matthew at Telescopes and astronomy in S.A. is a supplier. Reguard's Tony
