Dave, the histogram was fine but you might like to get is a little to the left now, not much, just a little. Your slightly overexposing. But this is a great point to start from.
When you get the barlows the image exposure will drop back to 1/50 or 1/33.
I forgot that you don't have tracking, so this is still pretty good, just bear in mind that this will get much harder once you place a barlow in. So follow Mike's tutorial on dob imaging. He perfected it and gave a really good tut on it.
As for the raw colour mod, make usre you have the right one. There are two on the web site and the one you want is not easy to find. It just makes the image on the screen look less grainy and gives a smoother finished image after processing. I use K3CCDtools for all my image capture on planets and find it the easiest to use. Anthony (Bird) says that I will eventually get sick of my current setup and head in his direction. I suspect he is correct. Still I like a challenge and need to address a lot of other issues with my scope before I head in his direction.
I don't use Iris so I don't know much about it, nor have I ever used ppmcenter, perhaps ask Mike or Bird. Anthony wrote it and would know. When you resample try using the Mitchell Filter that seems to work better in my opinion and it was a suggestion from Anthony. As for floating point error, go to tracking in registax3 and uncheck the warning on checking. That should stop it. If not just restart it.
Stay at 5 fps where possible, you will get a smoother image as a result. On bad nights use 10. I tried using 15 but found this create bad artifacts that I could not get rid of.
Happy to help Dave, just cool it down on the hero worship stuff, I get embarrassed and it is undeserving. Bird is the man you should be praising, his work is way cool.
Regards Paul
