This was taken with the Takahashi BRC-250. I will be doing autoguiding at some point as well as flats (which I've still not tried), it is a question of finding the time to get it all sorted out. Currently I still use the Paramount as it came out of the box so no PEC or protrack has been used, it is down to getting an accurate polar alignment. I did think that the 5 minute subs of Ha may be a little short but as the scope is f5 I thought I'd be able to get away with it. Probably try for longer next time round
