FYI you got some beautiful images of Comet Lovejoy with a thin but long tail about a month ago. They were terrific. You must be getting senile - Sorry about that :) ----- Original Message ----- From: "Dave Gary" <davegary@me.com> To: "Utah Astronomy" <utah-astronomy@mailman.xmission.com> Sent: Saturday, March 14, 2015 2:34:44 PM Subject: Re: [Utah-astronomy] Comet Q2 Lovejoy 03/13/2015 ˜22:00 For this shot I used a William-Optics 81mm Gran Turismo telescope on an iOptron iEQ30 mount. The camera I used this time around was an SBIG 8300C. I think the exposure was around 2 minutes, binned 2X2. You only get color if the binning is 1X1. I got some color shots, but they seemed a little lame. I was trying to see the binary because when I did the fine focus adjustment on Gamma Cassiopeiae the FWHM data was giving two peaks. I looked in Sky Safari and, sure enough, Gamma Cassiopeiae was listed as a binary. I think you can see it in the photo, but I’m not sure. You’re right about not seeing the comet's tail visually. I couldn’t see it either. I looked at this comet a few nights ago through my Meade 10-inch LX200 Classic. I couldn’t make out a tail on the comet with that scope. I may have some photos through that scope. I can’t remember. They must not have been very good because I can’t remember or I’m getting senile, or both. Dave

Great shot I was looking at this same comet last night. What kind of setup do you use? I was looking through Orion 130ST and I didn't see the tail as well as your photo, but lots of light pollution and I am just getting the hang of things (third night with a telescope after about 20 years and first decent scope I have ever owned).

Quick photo of Comet Q2 Lovejoy last night. The bright star to the right of the comet is Gamma Cassiopeiae (Navi). It is variable binary with the brighter star having a magnitude of +2.18 and the dimmer companion having a magnitude of +10.88. I think the dimmer companion star is at about the 3 o'clock position...very faint. A satellite passed through the field of view to the right of Gamma Cassiopeiae. The diffuse light in the left corner of the photo is the shadow caused by my neighbor's tree.
Improvements need to be made to the Driveway Observatory. Now, where's that chain saw? https://www.flickr.com/photos/78046474@N06/16605088147/in/photostream _______________________________________________ Utah-Astronomy mailing list http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Send messages to the list to Utah-Astronomy@mailman.xmission.com The Utah-Astronomy mailing list is not affiliated with any astronomy club.
