It looks more like a tracking error that collimation. The softness could be because the focus is off a little or because the tracking is too aggressive and overshoots and corrects frequently. Since you ate stacking images I would suggest shorter exposures to see what that looks like. ------------------------------ On Tue, May 20, 2014 3:17 PM MDT gazebo4sale(a)comcast.net wrote: >Don, >Thanks for looking.

Collimation
by Dave Gary 22 May '14

Don, Thanks for the reply. Hopefully, I never have to send my refractor back for collimation. So far, it's been outperforming it's operator by a long shot. Dave Sent from my iPad

Problem with list messages
by Chuck Hards 22 May '14

22 May '14

I'm wondering if any other list members who use gmail have this problem. Any list messages originating with a person with a yahoo address are getting sent immediately to my spam folder. Since I don't check the spam folder often, and sometimes just delete the entire contents sight-unseen, I've missed many recent list postings. This just started a few weeks ago, judging by the dates on messages I've seen in the spam folder. If you have list messages sent to a gmail account, please check your spam folder and see if you are having the same problem with utah-astro list messages originating at a yahoo address. Thanks! C.

Refractor Collimation
by Dave Gary 22 May '14

22 May '14

Thanks to everyone for the information. Chuck, your answer was very informative. I’m saving it for one of those “just-in-case” scenarios. I’m not having any problems with my scope or mount, yet. I was just curious about refractor collimation. Hopefully, I never have to attempt a collimation of my refractor. It sounds as if it could be quite intensive and hard on the nerves. Dave

Our Sun has a sibling!
by Thomas Sevcik 21 May '14

21 May '14

This should be a hit at star parties! Imagine showing the public a nearby relative (well, not that nearby at 110 lys) to our Sun. And the fact that it's visible in low power binos and small scopes. There's also a link near the bottom of the article to download a 410 KB JPEG chart (my best guess is that it's near the double/multiple star 90 Hercules) that identifies HD 162826. http://www.utexas.edu/news/2014/05/08/sun-sibling-astronomy/ Tom Sevcik
