Thanks for the replies Guys.
Kevin the crop was from the side but all the starts accross the field showed the halos.
You got that right Gary, I think someone in the area has bought a new telescope in the last 4 days. I ended up getting the Whole Shebang out later when it cleared up a bit. I haven't looked at or processed the images yet so I'll let you know how they went. Unfortunately Machholz was out of the picture by then.
Mick, yes the halos are present in the originals . I was using a shutter release, though from past experience with my other canon they seem to have a pretty savage mirror flip, The tripod it was mounted on certainly isn't the Rock of Gibralta. I'm not sure about the lense type, though I would imagine that it would be at least Achromatic. I'll check up on that.
Ok so to start working on these issues.
1. mount my camera on telescope for longer than about 2 sec.
2. get a sturdier tripoD or mount my camera on telescope (Well I guess that takes care of 1. too
)
3. Check out lense quality
Thanks again. I you have any other thoughts let me know.
