Free image data from AG Optical Systems observatory

The AG Optical Systems observatory is up and running in northern Alabama.  We have uploaded to DropBox some initial data acquired over the past month for NGC 3628 The Hamburger Galaxy, M65, and Markarian's Chain that is available to anyone for free.  The data is raw (no processing at all) and includes bias, dark, flat, and light frames.  As we are still tweaking the 14.5" iDK imaging train a bit, the flat data relevant to a specific object is included in the object folder.  Please contact AG Optical Systems if you would like access to the data.  We'll need your email address so we can send you an invitation to the DropBox folder.  And don't worry, we're not going to send you any unsolicited email.  We hate that stuff as much as you do.

Please feel free to post your images anywhere you like but we ask that you credit AG Optical Systems.  Also, please send your processed images to AG Optical Systems so we can share them on our Facebook page.

While the data is free, you are on your own when it comes to processing the data so please do not contact AG Optical Systems with image processing questions.

As the AG Optical Systems observatory acquires more data we'll upload it to DropBox and announce it on our Facebook page.  The data will always be free with no catches.  AG Optical Systems values the amateur astronomy community and this is a way for us to show our appreciation.

The observatory currently houses two premium imaging systems.

   AG Optical Systems 14.5" F6.7 quartz astrograph

  • Software Bisque Paramount MEII equatorial mount on 10" Paramount pier
  • ZWO ASI6200 full frame camera with EFW LRGBHa filters (we're tweaking the filter setup to minimize vignetting)
  • Borg 50mm piggyback guidescope with ASI120 guide camera
  • Ultimate Power Box V2
  • The SkyX
  • TPoint pointing model
  • PHD2 guiding software
  • Optec TCF3 FocusLynx focuser

    Stellarvue SVX102T with flattener/reducer (535mm focal length), 3" Feathertouch with Optec focus control
  • Software Bisque Paramount MX+ equatorial mount on 8" Paramount pier
  • ZWO ASI6200 full frame camera with EFW LRGBHa filters
  • Williams Optics 50mm piggyback guidescope with ASI120 guide camera
  • Ultimate Power Box V2
  • The SkyX
  • TPoint pointing model
  • PHD2 guiding software

All of the data has been acquired using Voyager Astrophotography Automation Software.

The reducer on the Stellarvue SVX102T shows some star distortion towards the edges of full frame images so you will likely need to crop that data.  We have a flattener on order that should provide full frame correction and we'll get it installed when it arrives.

The observatory is a 24' x 10' roll off roof design with roof automation provided by the SkyRoof system from Interactive Astronomy.  Weather data is collected by the SkyAlert system from Interactive Astronomy.  We have some images and videos of the observatory on our Facebook page.

We have several other scopes that we plan to rotate through the observatory including an AG Optical Systems 12.5" F3.9 Harmer Wynne, an 8" F15 Mak with TEC optics, an 8" F20 Mak binoscope with TEC optics, a 280mm F12 SCT with Lichtenknecker optics, a 10" F15 Dall Kirkham with Ostahowski optics, and our lineup of 10" to 20" iDK F6.7 premium astrographs.

If you are in the area feel free to contact AG Optical Systems if you'd like to see the observatory.

Attached is the first light image from the observatory.  It consists of about 20 hours of LRGB data of NGC 3628 The Hamburger Galaxy collected using the AG Optical 14.5" system.  The data was processed by Patrick Sparkman ..... he did a great job!

Enjoy!
