INDI Library v2.0.7 is Released (01 Apr 2024)
Bi-monthly release with minor bug fixes and improvements
Polemaster as CCD with Telescope simulator
Polemaster as CCD with Telescope simulator was created by Adrian
Very Cloudy tonight so I tried to use the QHY Polemaster as a CCD on Ekos/Indy.
Seeing was very poor with the bright moon and lots of water vapour (moon bows never a good sign).
Server on Raspberry Pi 2, Raspbian Stretch with latest Raspberry Pi Download from Raspberry Pi Stretch Download .
Clients Kstars 2.8.9 (Build: 2017-12-16T19:22:20Z) on Arch Linux and Kstars Lite on Android(s)
It took pictures nicely (see attachment which demonstrates the large FOV. Astrometry worked nicely when the
focal length was set correctly in the telescope simulator.
Fits header
Streaming worked on Kstars, the first image used the settings from the preview snap but then the stream used
someother settings which altered the image (? can only change it by changing the gain). I recorded a ser file but haven't
been able to compile the ser-player program yet to see what they are like.
Kstars lite initially let me preview the image that I took with it but then seemed to only keep offering the same image which
was not the current one. I must have got it confused somehow, as I was attaching to the indiserver from the PC and two androids.
You can see the clouds nicely (sic) in the image and I wondered if this might be useful.
Does anyone use a second Kstars do monitor an all sky cam?
Anyhow the image is great for a 1.2 second exposure (? had gain at 50) in poor viewing conditions.
Super.
