  I'll try again, since replying to the post wouldn't take.

Yes, get rid of the spam below this message. How do I keep this crap from showing up on my friends list w/o unsubscribing to Astro_photo?




Some Tuesday SHINY

..And unlike other image posters - I won't bork-up your LJ!

How, you may ask? Well, that's easy - if the image is larger than 800 pixels wide, I'll put it behind a cut tag. It's an easy thing to do and I wish more of my readers would practice this simple measure.

OK, enough bitching - here's a few new SHINY taken over the weekend.

We'll start off with a couple unconventional lunar craters., By and large, most craters are round and/or polygonal in shape and have bowl-shaped floors. Oddly shaped craters imply unusual circumstances and/or modification by geologic forces. One of the largest and weirdest looking craters on the Moon is Schiller.

What do you think it looks like? A gourd? Footprint? Or something *else*?

Orion Min-EQ Tabletop Equatorial Mount w/EQ-1M Electronic Drive System 
11:52pm 05/08/2009
  I'm going camping in Cherry Springs, PA this month and really wanted to try my hand at astrophotography. Seeing as I'm almost never around dark skies, I don't want to drop a lot of money- but do want to try taking exposures longer than 30 seconds w/out trails. I was wondering if anyone has tried the Orion Min-EQ Tabletop Equatorial Mount and if it would be good enough for 5-15 minute shots w/up to a 50mm lens?
Or has anyone had success w/ a barn door tracker?
If you've had good results from either the orion or a barn door- could you pretty please post the pics?

Jupiter And The Galilean Moons;

In Order: Callisto, Ganymede, Jupiter, Io, Europa.
Photographed at The Cheltenham Badlands, ON.

i know it's not the most fantastic photo, but the fact that my little Panasonic Lumix could capture Jupiter and 4 of its moons made me squee a little bit ;)

is anyone watching the occultation of 45 Cap tonight?

I'm a newbie to the sky, just wondering if that's Venus or a star below the moon?

A Collaborative Effort

If you had attended Pixie's b-day party, you might have noticed the absence of the doctor for a couple hours. Some of that time I was observing and check in the field, at other times I was busy imaging. eaterofgodz and I were working on making a Lunar Mosaic with his old 6.3 MP Canon and my 12-inch LX200. After a lot of test shots to set the proper focus and exposure, we set about making the mosaic.

Using the dual axis drives, the Moon was subdivided into 6 sections. At least 5 exposures were taken for each section, the best would be stacked and used for the final composite.

Other specs: 12-inch LX200 at f/10 (focal length = 3.04 meters)

Later that evening, eaterofgodz worked on smoothing out and getting precise matching of the sections to produce the mosaic. He would send along .tif files, and I would sharpen (using unsharp masking) and work on adjusting the contrast.

First, a small image:

This is the first of (hopefully) many new collaborative astro-imaging projects including LARGE lunar crescent (plus Earthshine) and Full Moon phases, Milky Way clouds and huge nebula vistas.

Spotting scopes? 
06:53pm 18/11/2008
  Have any of you ever had experience with a spotting scope such as the Celestron C70 or C90 Maksutovs? Until I save up enough for a full-size telescope, I figured a spotting scope would be a great way to start observing and photographing. If you have another recommendation, that's even better.

The Milky Way 
10:17pm 29/10/2008
  I'll make this short:

I'm interested in taking some photographs of the night sky, and especially the Milky Way. I live in East Tennessee...is there any particular place I should go to view the Milky Way, or will I be able to find it at the right time/looking in the right direction anywhere that lacks any sort of artificial light?

Also, any other tips for finding it or where to look are greatly appreciated. Thanks, and I've really enjoyed looking at the photographs in this community...I'm quite new to photographing the sky.
