Re: IR filter removal from new RPi camera

Repeat of my previous post with the missing picture.

a small screwdriver placed as per the picture and gently rotated
was enough to part the two pieces.

Re: HQ camera and a telescope noob question

It looks like you have 0.965 inch fitting eyepieces.

cost appear on e-bay if you do a google search.

Good luck.

Re: Raspberry Pi High Quality Camera

Waiting for the rpi-update I used V3 on a 80 mm refactor telescope to do similar time-lapse exposures to those I had made with V2s. Settings such as raspistill -t 30000 -ex night -ISO 800 -bm -tl 0 -o timelapse1%d01.jpg were used with -ss varied between 5000000 and 30000000. I found that, for exampl...
