Wheaton46 - status 27 Aug 2012.

Shelter has been constructed, and power/data cables prepared.  (Wind fence will be installed later.)

Telescope/mount is here, in pieces.  Need to test (in the garage) drive system and focuser.  I want to be sure all electronics work and interface properly with the control computer before I move the rig to the shelter.

Control computer has most software installed.  Final configuration and script tweaking will take place after first light.

CCD (ST-8XE) has passed bench testing.  See attached graphic - at 1x1 binning this camera is linear up to about 44,000 ADU.

Read noise is about 18e-.

Gain is about 2.64 e-/ADU.

Dark current is about 0.35 e-/pixel/second at -10C.  (System will probably operate at -20C.)

These are typical test results for an ST-8.

AAVSONet telescope Wheaton46 should be operational in about 4 to 6 weeks...depending on the findings from various under-the-stars tests.

Here is the attachment - CCD ADU rate for various exposure times (using constant light source).

Thank you for all your time

Thank you for all your time and effort bringing another nice scope into the robotic network!
