Foursome from a Sony consumer camera

Posted By Roland Christen
These images were taken with a 175EDF refractor using my Sony NEX-7 digital camera. Exposures were limited to 30 second shots, approximately 10 to 30 each, stacked in MaximDL.

The Saturn pix was a single 1 sec exposure for the Moons and a series of 1/30 sec exposures for the planet, superimposed on top of the overexposed 1 sec planet image.

Just having some fun with this camera to see how well a simple consumer digital works with an amateur telescope. The images are all to the same scale, by the way. The M27 image is a bit fainter than the others. I only had 8 of the 30 sec exposures, plus it is a fainter object. The Blinking Plaetary surprised me at its brightness.

It was a calm and steady night ...

Posted By Roland Christen
So I grabbed what scope happened to be setup in the observatory and aimed it at the Moon and Saturn. The seeing was maybe a 3 - 4 out of 5. Here is what a 155EDF refractor can do with an AP 2.5x Advanced Barlow and a cheap and cheerful QHY5 Cmos camera (at $300 bucks they are a steal!).

First shot is Saturn, approx 7000 frames at 100 frames/sec

Caught CopperNickolaus on Thursday night just in the right spot to get some detail.

Testing a 12" astrograph

Posted By Roland Christen
This is a central crop of a test object that I like to use when testing scopes at the AP observatory. Image taken with a 12" astrograph at F8 using a 16803 FLI camera. 10 minute exposure on a slightly hazy night. I processed it in MaximDL to bring out the faint stars without blowing out the detail in the core.
