Hi all!



Finally had some fair skies Fri. night to test out the new G11/Gemini. I'm fairly happy with the results!



I did a 10 min run, and one point worth noting is that skies were really turbulent, with some clouds intermittently creating some problems (guide star would disappear for 10 sec's or so..... While understandibly not "ideal" for running a PE test, the results were remarkable! Max error of +/- 2 arc-sec! Due to the bright guide star necessary, I was using 0.1 sec. integrations, which I did a running average to produce the graph to smooth out due to scintillation and poor seeing. What impressed me most was that the unguided star image stayed WITHIN the tracking box of CCDSoft during the whole run! Something I couldn't manage even for 10 seconds with my old LX200!



Graph's here for anyone interested:



mywebpages.comcast.net/bobbenamati/MyHTML.htm



Error's in arcsec, taken unguided w/ST-7XE, 8" SCT, operating at f/10.6 (due to TCF and CFW back-focus, effective f.l. increased to 10.6)



I am anxious to get some "good" data under good skies to really get a true evaluation, but the prelim. results have me feeling good about the purchase!



Clear skies!

Bob

Hi Bob,



That's phenomenal performance and as good as I'm seeing currently

with my Titan!



Take a look at www.heavenlyview.com/titan.htm for

comparison. I finally was able to get my website back up and

running and promised some of the people here the link to the PE of

the Titan.



You should be able to get some very nice higher res images with your

new setup! With my LX200, I was limited to f/4 and below for

imaging. Forget about f/10 imaging of planetaries!



Have fun and clear skies!

Thanks, Alan!



I did see your post the other day, and was truly shocked! I was very curious if the new G11's were able to produce as "touted" by the upgraded worms that are now "standard". I've seen some bashing going on at some of the other CCD imaging web-groups, and was really hoping to prove that wrong!



Just for the others who may wonder..... the mount is "out of the box" condition.... no mods done or adjustments in any way. I checked the worm mesh and snugness once I received it, but the assembly seemed perfect-- so no tinkering was done or apparently necessary.



I know the LX frustrations all too well ;-) I was NEVER able to shoot at f/10.... almost all of my imaging had been relegated to f/6 or faster. It'll be nice to finally be able to image at those higher f's! Planetaries were always beyond the capabilities of my LX..... Can't wait to finally add them to the archive!



Clear skies, and enjoy the Titan..... Really nice piece of hardware! Looks like Scott's really on the road to having one of the most cost-effective, high-end mounts out there!



Bob
