Last night I was able to collect three hours of data on this object. I'm still learning how to use this camera but so far I really like it.
36x300s + 10x10s for the stars. Gain 120. For this image I used the Vixen R200ss with the Vixen corrector PH. I'm still chasing down the annoying reflections on the bright stars. I'm making some tweaks to the mirror cell that I hope will solve the issue.

I think that CN's algorithm messes up the color a little bit. Here is the link to the Flickr image. It's reduced but I think it looks a bit better than on here. https://www.flickr.c...eposted-public/

I hope you enjoy it and feel free to critique!

Sorry about the silly question, i have this camera but i haven't had the chance to try it, you use the autoguider connected to the camera or to the mount? I'm kinda lost...

  I agree with the colors being messed up on CN.  I quit and just post the link to flickr. 

 

  Amazing what can be achieved with these cameras.

Very nice for a single-shot color camera.

I connected the auto guider to the computer but I don't think that it makes any difference. You can connect it to the camera and that will eliminate one USB cable going to the computer.

 

For auto guiding I use pulse guide so there is only the USB cable that connects to the auto guider. If you use ST-4 then the ST-4 cable will go from the auto guider to the mount.

Excellent Andi, ive been hoping to see more of your data. Did you get a chance to test with the 135 as well? Awesome job!

Thanks Wes. I need to reprocess this data as I have some hot pixels and I forgot to use cosmetic correction!

 

I didn't get a chance to put it on the 135mm yet. I could do it tonight but sitting at my desk with a glass of red isn't curing my laziness and a 2 hour drive right now looks very unlikely :)
