Dedicated digital astronomy cameras (CCDs) are usually cooled to help control digital noise during long exposures.  Using "stacking" techniques and the DSLR, it is possible to take a number of shorter exposures, and combine these into one image as a way to reduce noise.  See the results yourself!

Takahashi TOA 130 Telescope

 The TOA 130 (on my old Losmandy G11) ready for action at the old  NHAC Neal Site .  Dig the Crepuscular Rays.   See Cloudscapes for info on Crepuscular Rays.  See http://www.ems.psu.edu/~demark/471/CrepuscularRays.html

The TOA 130 is a 1000mm f7.7 focal length APO triplet lens refractor.  With reducer, focal length is 754mm at f5.8 


Takahashi TOA 130, Losmandy G11, dual saddle plate, Celestron "short tube" ST 80 being used as a guide scope with the SBIG STV atoguider.  The Canon EOS 20Da camera is connected to the TOA 130.  You can also see the Rigel Quick Finder on the left of the TOA, along with some dew heaters & associated power cords.


G11 Imaging Setup

Above: Losmandy G11 mount with DSBS dual saddle plate.  TOA 130 on left, ST80 with the STV CCD head on the right.  STV controller on the bottom (between the legs.)

In English, a refractor is the type of telescope familiar to most people, very similar to an old "spyglass" in design. Refractors have lenses near the front of the telescope, with an eye piece (a small lens) in the back. 

For Photography, a camera is connected to the back of the telescope, the part you would look through.  With reducer, focal length is 754mm at f5.8  See next

My trusty Losmandy G11 has been replaced by an Astro-Physics AP 900GTO mount

Notes on guiding with the G11

I'm carrying a TOA 130 and a ST 80 guidescope on my G11. I had a challenge in getting the sculptor galaxy image... Due to a lack of bright stars in the region, I was guiding at maybe 4 second correction intervals. That just isn't quick enough for my mount, so I re-framed so that I could get a bright guide star with about 1 second corrections. That made a large difference in the quality of my stars.

 

Scopes, plus Venus, Moon, Mars, Saturn

Probably from 5/21/2004, definitely from West Texas in the Davis Mountains.  This shows my old Takahashi FS 102
