20" Sidewalk show

Horsehead Nebula

Don Himes sidewalk show

Hi Dave,

At last put together a dream machine sidewalk show...
Obsession 20" and TWO HDTV on a perfect Thursday evening...far superior to the smaller scopes I've run for years.

This is a high water mark in 15 years did walking it ...

Hi Dave -

A couple of years ago, I had sent you a photo of the Moon I took with my 25-inch Classic using an iPhone 4S.

Moon Tim Conners

On a whim, I sent the same photo to Astronomical League earlier this year. I Just received the latest issue of the Reflector and was amazed they published it on the back cover. Check out the attached.

I recently moved from Georgia to Tucson, AZ. I’m closing on a house next week. Our new home will be less than ten miles from the center of Tucson, but the skies here are surprisingly dark because of the lighting ordinances and the low aerosol and moisture levels in the air.

I have yet to buy a trailer to transport the scope, but plan to at some point so that I can bring it to some truly dark skies for the first time.

Take care -
Tim Conners



Straight Forward Prime Focus

Jupiter grazing occultation

Jupiter grazing occultation - Nov. 2, 2012

Hi Dave

Talking about having fun – the 18 inch Obsession + Canon DSLR (7D and 5D) – no stacking etc. – just straight forward prime focus (bottom part of a barlow lens -  attached to camera adaptor/ nose piece).

We were fortunate to see a grazing occultation and the photon shields (clouds) stayed away JUST long enough!!

Keep well.

CCD and video astrophotography

Horsehead Nebula

Imaging with a large aperture reflector like the Obsession is exciting. The large light gathering area means CCD exposure times are very short - usually under a minute. Minimal guiding or none at all. Multiple images are stacked in your PC to build up a vivid image. With proper software, field rotation at the focuser is elliminated.

Live video work is the ultimate in immediate gratification. The newer cameras are very sensitive. Entertain a crowd with deep sky images on the monitor. Actually see deeper than you can with eye at the eyepiece in real time! Or connect to a DVD camcorder or VCR and capture the video to watch later. Or make stills of the best shots.

Doug Murphy photos

Hi Dave, Long time, no write! Clearly, I’ve been having a good time with my 18UC. As you saw from the post I do a lot of video-astro imaging with MallinCam from the back yard, but the video provides a live feel to observing that guests and visitors get excited about, and the views with extreme light pollution in suburban DC are like views you can get in a 50 inch under dark skies. And then again there’s the color. It's a great way to go. Feel free to use these photos. Emphasize that they are just video frames. They match very closely what you can see live looking at the color monitor next to the scope. Here are the conditions:

So you see, I’ve been lovin my 18UC and having a wonderful time with the stars. My mirror is a beauty. These are recent photos of the March skies.
