I did not do any guiding for these images. My computer had a meltdown. Other than some darkening in the raw file there is no other processing on the images.

You're welcome Phil

For a quick answer most any day I can be found in the chat area of this site. Drop in and say hi.

Thanks Russ, I really appreciate your help. Vega appears right beside one of the palm trees but if I can catch it early I should be able to get a few shots off. Too funny like you I have a pile of stuff not in use that I should have returned. We should get together and have a garage sale in Flags Town Square:). This hobby is certainly a challenge but is also personally rewording. I consider myself lucky to even be able to be part of it and my frustration goes away. It is also great to be able to reach out to folks like you and Marc. Your time is really appreciated, Phil

Tonight try it without the FR. If you get any reflections add your dew shield to block any unwanted light. Maybe go after Vega which is just west of straight up. That might help block unwanted light.

Good luck and keep smiling. All in all you just have an unwanted adaptor. If my unnecessary purchases were only limited to a few adaptors I'd still have pocket change.

Sorry about that I missed the "0", it is around 110mm from the sensor. Stuff like this drives me nuts which is mostly caused by me not understanding this stuff. I purchased all this stuff last year and before I did I sent Optcorp photos of all my gear including the scope. At the time I was told the set up will work the same with and without the Crawford focuser. Now I am assuming there would be a difference in the image if I was using the Crawford focuser.

Thanks Russ and thanks Marc.

That picture sows a lot more than 11 mm which is roughly 7/16 of an inch. Marc is right and I forgot about the all important spacing between the face of the glass at the back of the FR and the face of your sensor. If I remember correctly, the EOS adaptor give your a measurement of roughly 40-44 mm from the outside face of the adapter to the face of your sensor. That means you have to have an adapter no more than 1-1/2 - 1 5/8 inches or the balance of the difference of the measurement of the EOS adapter. The inside of that long barreled adaptor could be causing some of those reflections as well.
Ya, now that I'm seeing this picture of your camera I'm convinced much of the issue is the long tubed adaptor.

Hi Marc, Thanks for the input. I just did a rough measure and from the chip to the FR is around 11mm. Here is the camera set up. Russ is this somewhat like yours. FYI I did not use the adapter on the end that is for use with the Crawford focuser.

Philip, I have ant6.3 that I've used on a c8+c6. I'm not sure if that is the problem w/the star reflection (try out Russ's sug). However the stars in the corners (zooming off) is a spacing issue between the chip and the FR. The Antares is suppose to be 82mm (give or take a bit) from the ccd chip. There is some play w/this number depending on your chip size and the scope fl. In the pic my internal chip distance (chip to outside the filter wheel) is 38mm so with the adapter and spacer in place it makes up to (about 82ish lol, my point is you need to play w/it a bit to see what is acceptable to you ie there is always the crop tool). This could maybe (a big maybe) be also causing the reflection if it is too close. Good luck Marc

Hi Russ, I agree the process of elimination will tell the story, good advice. The ISO was 800. I did not have my dew shield which is not a real dew shield as it is just one of the plastic Celestron Velcro tubes. I will try that first tonight. If that does not work I will take out the FR and see what happens.

I am not sure if I am on PHD2 or not.....I will check that out. I do know I have great focus on the guiding. Thanks for the PHD tip and the links, very cool. I am exited to get back out tonight and do some more testing. Thanks so much for you help............really great man. I will post what I get tonight tomorrow morning........again thanks man.
