Legacy software is C and  x86 assembly  for telescope control, Labview and Delphi for data processing. Moving to C#/F#/Python/C for all tasks

In-Sky Safety / Re: On telescope camera for plane spotting

In our experience FOV is  sufficient  to have  a time to manually use safety switch to block outgoing laser beam. From the other hand - plane entering FOV of camera is a quite rare event for our system and location.

We are using Mintron CCTV attached to telescope,  approx 2x4 deg FOV, plane navigation lights are visible in night.

Telescopes / CCTV/ICCD/EMCCD cameras for tracking
« on: January 17, 2017, 07:08:59 PM »
Any ideas or suggestions for ICCD/EMCCD/CCTV camera for tasks like  visual tracking and star models? In a few SLR publications ICCD cameras are mentioned, like  https://cddis.nasa.gov/lw14/docs/presnts/atm1_zzp.pdf, but no details on specific models. The options are like starting from CCTV cameras used also  in astronomy like Watec http://wateccameras.com/productline/cameras/910HXEIA and ending like Andora Zyla 4.2 PLUS sCMOS(?).
Requirements besides the obvious to see as much as possible:
1) Programming API, e.g. we should be able to define and display reference marks
2) Gating - we should able to shut down  camera/close shutter at certain moments
3) Pixel size, sensor size and mount are important but here we have some freedom, px count is not so important. C-mount and 1/2" CCTV like sensor size should do fine.
4) Expected lifetime - should handle regular use in tracking
Applications:
Visual tracking, mount models, and optionally experiments like described in "Optical Characteristics of the Retroreflector in Space on the ADEOS Satellite in Orbit", where ICCD was used.
