Hi


I am based in Sydney Australia and tried to polar align with a Polemaster camera using SharpCap last night

unfortunately Sharpcap couldnt find more than 4 stars - found two then three and then four and then fell back to 2. I was pointed very close to sigma octans -could see it clearly in the snapshot.

I could see plenty of stars in the snapshot which I have uploaded to my flickr account temporarily

so in effect I never got to even step 1 of the polar alignment routine

what am I doing wrong? Help would be most appreciated

many thanks in advance

Hi,

did you look at the hints on this page? https://www.sharpcap.co.uk/sharpcap/fea ... leshooting

Sounds like you need more exposure/gain to get more stars to show up.

cheers, Robin

It looks to me like your exposure is too long, making the background level too high.
My settings for a Polemaster in Auckland suburbs are Exp=150ms, Gain=70.

Steve.
