paul Posted January 24, 2021 Share Posted January 24, 2021 All my previous M45 attempts were time limited under very poor conditions. This is the result of about 20x300sec @IOS800 with the 550D and 150mm newt:The data was promising but as you can see it has a few issues; a result of experimenting with the Optolong L-Pro 2" fitted to the coma corrector (scope end). The stars are so bright that they generated "impressive" ? multiple donuts. I now have the clip version but my viewing opportunities for this object are limited. If I can get some time I may switch to other equipment. 3 Quote Link to comment Share on other sites More sharing options...
