Hi Folks

I have a portable set up and have gotten better at getting a decent PA. To that end the last few times I've been out imaging I've been able to successfully take repeated 7.0 minutes subs at an ISO of 800 with no elongation of the stars in my subs. Now for the question. ;-).

With the current warm weather (I'm in country Victoria at present) is it worthwhile trying for longer subs - eg 10 minutes at ISO 800 on the Canon 60 Da? I'm really tempted to have another go at imaging Thor's helmet.

I'm still very new at this and finding my so any advice would be much appreciated.

Paul
