I am selling an SBIG ST-237A CCD camera with the remarkable e-finder; FR-237 FOCAL REDUCER LENS. Also including is the SBIG TIC tracking interface cable .The unit is in prestine condition and has been used only several times. When the focal reducer lens is used on an f/10 SCT it will increase the field of view and reduce exposures by several times. The same lens can be used with the eFINDER assembly extension tube (also included) which turns the FR-237 lens into an ultra compact f/4 telescope of 100mm focal length for very wide field views or Autoguiding without any additional optical tube.
This camera is absolutlly *perfect* for the Fastar-compatible OTAs. The ST-237A has increadible high QE (quantum efficiency) which can not be beaten even by double cost CCD's. The ST-237A also has an internal mechanical shutter in addition to the CCD's electronic shutter.This feature is seldom found on cameras in the price range of the ST-237A. The ST-237A got me hooked on CCD imaging and I would like to move up to a higher end unit now.
It comes with all the original software, manuals, cables, and boxes.
You can now also use it in order to obtaining high quality 180 degree views of the sky with the new SBIG 'ALL SKY lens'! wonder
what a meteor shower will look like with this thing.
If you are interested in very high resolution planetary imaging where structure and detail are prominent, the Model ST-237A, used with longer focal length refractors or SCT's, is an ideal system for your needs.
Please email me with any questions you may have. ST-237A images can be seen at the sbig website. If this sell will go well I would consider to sell Meade’s broadband Nebular Filter 1.25" 4000 at a give-away price!
Price for all of the above is only $1365 including the e-finder; FR-237 FOCAL REDUCER LENS unit & the SBIG TIC tracking interface cable & CCDOPS plus TheSky v.4, CCDSoftV5, CCDSharp, manuals and cables.
