Here's a comparison of the Sun in UV and Ha. Taken with Lunt 60mm CaK and Ha telescopes. I picked up the CaK at the ASAE show in Tucson a few weeks ago. I can actually "see" in UV now that I have had my cataracts removed. The camera was almost lined up to show the different surface details side by side. http://www.flickr.com/photos/59454099@N00/11357211216/ J D Maddy Clarkdale, AZ -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
