Titan Transit Teaser 20090224

Observation logs

I think there's a name for titles like that, but at 25*F and early in the AM my brain's not so straight.

Bad seeing too.. looked like the whole continental US had bad jetstream. I hope someone west of here got better as it was fairly low on the horizon here.

I forgot about the time delay in stellarium but that was OK as I overslept a bit anyway. Most of the frames are washed out by the trees but you can make out the shadow in the final 3 or so frames. I also caught Dione in a few frames riding the upper left ring, long before it's transit. So no quad transit, but I was able to get something and that still counts! Lucky me, the sky was clear.

Comments:	Didn't leave the scope out overnight and it may have impacted some but little of the conditions. I miss timed the Titan Transit becuase of the time delay / light propogation issues with Stellarium. I fixed that now1

Failed Rosette 2009-02-16

CGE with Meade LXD55.
3minute subs x 34
no dew / light shield till past half way of the observing session.
no light pollution filter
no guiding

1st image is a raw stack with no stretch
2nd image is flatted (but why the poor 'gradient'?)
3rd image is NOT flatted, but had some gradient removed in Iris

Added some new brid photos..

Great seeing on Saturn 2009-02-07

Best seeing I've seen since early September! I used the lymax cat cooler extensively, for 30-45 minutes at times. Re-collimated and ran some tests on the moon. Starting imaging long before Saturn hit the meridian and just before I got too tired to stay awake I tried a monster 5min per channel LRGB session. The CGE was up to the task and I had to do very little corrections. This is the result. My best of the season! I managed to catch at least two moons that I'll have to process seperatley and post later.

I was happy to see such steady seeing after an average start. Some things that I payed close attention to while processing: Shadow of rings on globe, shadow of globe on rings on lower right, Cassini division on both sides and growing gap between the rings.

Also, to all you youngin's out there (Hey, I'm a stark 33 stil!), when the seeing's good make sure you spend some time soaking the light of the object into your eyes. It's all to easy to get wrapped up imaging. I smiled big for the views on my screen but even more to see it sitting still in my 4mm and 9mm eyepieces!

Steady Skies,

Mike

*My* 1st light with the new setup - M81/M82

Begin:	2009-02-04 um 20:08:01-05:00
End:	2009-02-04 um 23:59:00-05:00

Weather:	S:? T: 3?/5 Clear, cold and WINDY!
Equipment:	Optics: Meade LXD55 Mount: CGE mount on JMI Wheely Bars Focusing Aid: STI focuser Shutter control: Hap Griffin long exposure cable Software: MaximDL Operating System: WinXP Lenovo T43 driven via RDP from inside the house
Comments:	*MY* 1st light of the Meade LXD55 and CGE!!! What a pleasure to wheel the whole rig out of the garage into the driveway! Used my Celestron knowledge to get a rough align and was able to get fair results of 90sec+ exposures. At f/5 and ISO800 there is a LOT of LP Setup on M81 / M82 to get lots of subs, staying warm inside now as the outside temps dropped into the upper 20's Align was in the double digit of minutes error after a 2x iterative align. No PEC, no polar scope, no guiding, no drift align.
