Moon Jan 17, 2006

Leave a comment

With the temperature around 61º F, I went tonight just after midnight to grab a couple shots of the moon. Once again I am really disappointed with the results. The camera continues to bounce slightly when the shutter is opened… perhaps a little more weight added to the other end. The photos themselves seem OK but they are not sharp. They say practice makes perfect (who are “they” anyway?).

Weather permitting I hope to catch a glimpse of the New Horizons probe when it launches. If nothing goes wrong that should be about 1:24 PM EST.

The Moe-oo

If you read this post from a few days ago First Session of 2006, you’ll see I mention how one of the first things my son learned to say and identify by pointing was the Moon. I found the video we took of that night — December 26, 2003. Let me set the stage…

My wife had gone to Target (department store) and when returning to the car my one and a half year old son kept saying Moe… Moo… Moow… Moew… Mow… When she finally turned to see what he was talking about he was pointing at the Moon in the sky. To this point he had not ever pointed at anything before and since he was late to begin talking we had been kind of worried about autism and such things.

At any rate when my wife came home she called me outside and told me to bring the video camera. Maybe I’m biased (OK, I KNOW I am) but this is so cute!

You’ll need Apple – QuickTime to view this movie file.

Better Mount, Better Moon

I was able to get out tonight and get a few shots of the Moon before a hazy cloud layer streamed in. The temperature was 63º F with 88% humidity so a felt a bit warmer then Monday night’s 64º. Of course my son in his “PJs” was at the back door “I need to come out… I NEED to see the Moon!”

I cobbled together a temporary counterweight setup as I was getting SERIOUSLY worried about stripping the DEC axis of my telescope mount. The last two times I had the scope out with the Canon EOS 300D attached at prime focus I was seriously torquing the DEC clamp in order to hold the telescope in position… and then only barely. The camera assembly with the added right angle viewfinder adds 2.08 lbs to that end of the scope so it wants to pull the OTA back.

During the summer period — when the viewing here is at it’s worst and the jungle bugs are biting — I researched and ordered 2 of these counterweight sets from Astro Engineering (I mainly wanted the weights and the OTA screws and not the eyepiece mount) with the expectation of making something more permanent before this winter’s clearer skies arrived… I did not. So tonight I went into the garage and within 15 minutes emerged with these:





Clamped onto the dew shield they total 1.57 lbs. The telescope now holds in perfect balance with the DEC lock totally loosened. It will now pivot to any altitude and hold perfect balance without stressing the DEC lock in ANY way. I’m a happy camper! I will at some point fashion the design I originally had in mind which would allow me to easily add and/or remove weights in the dark. However in the interim, this works like a charm.





In turn the whole setup is now also stable against the camera’s shutter action, although I did STILL notice some wobble that needs to be addressed if I’m going to do exposures longer than fractions of a second. 🙁 But anyways as I started to say at the top of this post I was able to get a few shots before the clouds rolled in and nearly ALL of them came out better then the other evening. I’m still not quite “there” yet but I’m FAR more satisfied with the results I got against the effort I put in tonight.

While I’m here I thought I would point you all to this post on Space Photos that shows a time-lapse sequence of Venus taken over many months as it swings around to pass between us and the Sun. I get a weird “inspirational-our-place-in-the-cosmos” kinda feeling watching it. It’s VERY cool!
