I had the same problem, although to a lesser degree.. Turned out I could use my old 2 channel dewheater controller to control the voltage of my flatspanel, so now I just dim it. Needed a phono to 12v plug cable, those can be bought or made your self. Edit: If your flats panel is 12v that is..

Outstanding blood moon!

Then it might be because I over tightened the screws when putting the cc.. I'm scared of the camera falling out. Will check next time. I do plan to add a third screw, just need to buy the tools and screw. Thanks for the input!

Whoops! I did tighten it all up quite firm that night, will go loosen it now.

First of all, great shots Adam! I particularly like the Heart / Fish head.. Have you considered shooting a little RGB to replace the stars? How exactly does one over compress a coma corrector? Screw it in too tight?

Hi, I could use a bit of an opinion on this, I can't decide if this is tilt or spacing.. I don't think it is collimation, because that looks pretty much bang on as far as I can tell at least. CCD Inspector did say there was a little tilt, but with my limited knowledge I am not sure if it is enough to give these effects. To me it looks like something is affecting the right side of the image, and a little top left too. Any ideas?

Do they have different ascom drivers though? One of the contributors for NINA just built a dual rig, so he is working on dither synchronization in phd2..

Your unmodified camera will be fine for galaxies, reflection nebulae and star clusters. It's is only really the emission nebulae which are rich in h-alpha that warrants a modification, to let in more light. If you get a modified camera you will probably need a filter of the ccd variety anyway, to cut down on unwanted uv/ir which can cause star bloat. Light Polution is another matter, and can be alleviated with various filters. The harsher they are the more it will message with color balance. So it is worth looking into how much lp you have and what kind..

I will try this. Except for the stars then I also like this version, certainly more natural looking. I am looking into maybe separating the nebulosity from the stars and the processing them independently.. Do you shoot luminance for all your emission nebulae? Seems like some people think it is a waste of time. But if I want to use the RGB for a synthetic lum, then I think I need to shoot much more of it. Thank you for taking the time to comment (all of you) it is greatly appreciated.

With the Lighten Red method, and a synthetic luminance from the Ha brightened RGB. More details, but also more noise and stars are ballooning again.. So hard to get it right..

Ahhh I found out where I went wrong, I did not know about the split channels function. I am tinkering with it now, and it certainly does look more natural, but alot of the nice details from the Ha is missing. I really must try to get a good stack of luminance and see how that affects the overall image, like I said I haven't really shot any luminance since I got this mono cam. This false luminance is maybe a bit too noisy and lacking in detail..

I will try again, I must have missed something.. Thank you for the explanation.

I must admit that I don't shoot much L at all, I might have to change that.. With the weather being what it is, I tend to shoot all the RGB that I can when the moon is away and it is clear, and the rest of the time it is Ha. So often the Ha is much cleaner due to increased integration time and less lightpolution, this makes it very tempting to use it as luminance to tease out the details.

See I was trying to figure out how to do this because you and Ciaran were talking about it, but I can't seem to figure it out. I don't think I can blend anything when i'm in the channels tab, so I ended up making a new R channel with Ha and R data, and as you say using the Ha as luminance. Do I need to do it before i create the RGB master? Or is it some kind of color adjustment layer?

I agree.. It completely nailed this mosaic. Had I known that it would work this smoothly I would have gone for the full 4 panels.
