  1. @carastro Hi - the camera (my iPhone) was fixed to the tripod legs to look down the polarscpoe - and this is what my eyes are seeing too.

    My problems may have started when I loosened certain bits of the new polarscope - there were parts of what I assume was a polarscope? already in the tripod, and that had me confused.

    I think what I really need (post lock down) is some time with some people who can take a look at my set up and advise.

    Is there a North Kent, SE London Astrophoto group that have meetups?

     

  2. @ThomasF1234Hi - I levelled the scope, that didn't make a big difference, but the I did something spotted on another thread which is to add a grommet round the barrel of the polarscope.

    In my case I used plumbers PTFE jointing tape. I wrapped it round the top of the barrel and tried to get it snug in the tube of the EQ3 - assuming that's accurate.

    That seems to have made a difference. But I'm not sure it will be accurate enough to get me up to 1min or over exposures. I'll be happy with 45s.

    Being a novice, I seem to cause more damage than good due to lack of knowledge.

    Will try and post results if I can.

  3. I'm on an EQ3 and I have had trouble calibrating it.

    I'm trying to calibrate the reticule but ....

    It seems that barrel of the polarscope is off axis in the tube  - it sort of moves the whole image around, as if you were swirling a pair of  binoculars around.

    Maybe I can make a video.

    Is it time for me to buy a fresh one that I didn't meddle with?

    The outcome is that I can only shoot 20second images before the stars elongate.
