Observation Report for Jan. 5, 2009


Tonight, I finally got some clear skies to try out my new variable polarizer! I had done without one for so long, I haven't been able to observe the Moon unless it was a sliver. The Zhumell 10" dob gathers enough light that viewing the Moon without a variable polarizer can be quite uncomfortable! I took the image below with a point-and-shoot camera via eyepiece projection (basically holding the camera up to the eyepiece).

I bought my variable polarizer from Orion Telescopes. It does a pretty good job, and can block as much as 99% of incoming light. This makes it great for viewing the bright moon in large aperture telescopes. I can now comfortably view even tonight's gibbous Moon in comfort. The only problem I had with this polarizer was that at full blocking, it has that funky green coloration typical of many Moon filters. At lighter settings, however, this coloration doesn't seem to be present. Overall, I'd say it was a great buy!

Frosty Zhumell Dob

It's very cold tonight! Pictured above is the frost on my dob. That stuff is thick! Last I checked it was 15* F (-9* C) and falling. As I write this, I'm waiting (inside where it's warm) for Saturn to get to a higher altitude so I can see its nearly closed rings. Hopefully my optics don't frost over before then!

Clear skies!

That's an amazingly good shot of the moon... looks just like a DSLR shot.

I LOVE that pic of the frost on the dob... maybe because it's something I never see down here.

Just wanted to tell you that I love your site. I have been lurking in the background for some time, never commenting.

I find your information invaluable.

I also wanted to share some photos that I have taken of the Moon.

Thanks again for a great site.

Wow, nice work on those pictures! The first one is so sharp! I think this more closely approximates what one sees through a telescope!

I really like the HDR shot too, I guess the photographer in me is drawn to HDR ;)

Hi Sean! Fantastic shot of the Moon! I can sympathize with you where cold weather is concerned. Was -8°C here a couple of nights back, but it does make for excellent skies. No pain, no gain ;-) Hope you had a good observation of Saturn?

Sean Welton said...

Haha, to tell you the truth, I fell asleep before Saturn was at a reasonable altitude! When I woke up, the telescope was so frosted over that I couldn't even use it! :(
