I walked out to get something from the car and noticed jst how bright the crescent moon was tonight. Just had to click off a shot.

ISO 640, f/8, 1/60, Bigma @ 500mm with 2X TC, Manual focus and exposure

Shot off a tripod with 2sec delay.

Very nice! Must be nice to have effectively 1,000mm focal length.

Nice shot, Paul. Very clear. What tripod do you use?

Very well shot. What TC is this with.

With the crop factor wouldn't it be 1,500mm?

Thanks for the kind comments. Glenn, I was shooting off a cheapo tripod by Zeikos that I bought off eek-bay as a second tripod. It was my first try with it, and although it's rated as supporting 22 pounds, I wasn't real happy with the way it handled the big lens and TC combo. Normally I use a Bogen-Manfrotto with a pistol-grip head. The tripod handled the weight fine, but I think the weight was too much for the head. Fortunately, I really boughtthe new tripodfor use with the K10 and smaller lenses when my wife and I are both needing tripod shooting.

The TC is the matched Sigma 2X APO, Dennis. I forgot to note in listing the exposure detail that the real exposure was stopped down two stops because of the TC, so the effective aperature was f/16. I really like this TC with the Bigma, although it is certainly no candidate for hand-holding. And you're right, with the crop factor, the effective length is 1500mm.

Ishot this through my Orion Maksutov-Cassegrain telescope, using a T-ring adaptor and my Pentax K10D.
1300mm, f12.7, ISO100, exposure 1/30 sec.






Here are a few more of the full moon about a week later.
Same shooting info as the first one, at a few different exposures:

1/60 sec:





1/125 sec:



1/180 sec:





I don't remember what I did in the editting; it was a long time ago. But it must have been something stupid or the moon would be relatively the same size in both sets of shots. Probably caused the lack of clarity in the first shot compared with the second set. I'll have to go back to the original image and try re-editting it, now that I have a better handle on Photoshop than I did back then.
