First Light with 80ED DSPRO and 414EX

[joecoyle]

Hey

Finally the clouds parted for a while, so I thought id give my new setup a try. After being used to getting 2 minute guided subs with my Celestron NexStar 6SE, I was very pleased with the following 5 and 10 minute guided subs with the 80ED. Had to reset all the guiding params to default, so they may need tweaking in future (total RMS was 1.28" which I think is on the way towards good?). One thing I would like to check is in the image below (right hand image is the 10 min), the core of M27 is excessively blown out. Have I exceeded the well depth of the 414EX then? Or is in caused by something else ? The left hand 5 min just had an autostretch applied. What are people's thoughts on star shapes / focus etc...

 

Also in the image below, the histogram of the 10 minute sub looks very odd... its very shallow... and very far right. Any reasons for this? There were intermittent clouds around which may have affected it?

 

Fot a first run, I'm happy... theres obviously a lot to do, but would appreciate comments and thoughts as usual.

Cheers

Joe
