Planetary Nebulae with 10" f.5 Newt --> But what Cam
« on: January 08, 2012, 05:06:46 PM »
Hi forum,

What Cam could i best choose; i was interested by the Titan because of the relative small chips.
My 383l+ is to big for this kind of jobs or am I wrong?

Thanks for the answers mates!

Best clear skies!!

I would say that 10" f/5 is way too short for most planetary nebulae.

I use a Celestron 8" Edge HD w/ a 0.8 reducer for planetary nebula's (pn's) and at 1600mm fl it is probably a little too short for a lot of pn's.  However, one also has to consider sky conditions.

An ATIK 428Ex with the above scope and reducer yields 0.58 arcsec/pixel (as/p) which is oversampled for my normal 1-2 arcsec/pixel sky.  An ATIK 314L @ 0.83 as/p would be a pretty good match.

The above combo would yield a full frame image of M27 and be too short for M57.  You can't win them all!

A 10" Newt @ f5 is a nice fast scope and good for a large number of targets (I have a SkyWatcher 10" f4.8).  I also find it hits my sweet spot for tracking, guiding and polar alignment; any higher focal length and the whole configuration starts getting a bit shaky.

Aim for your sky conditions in terms of arcsec/pixel and you normally can't go wrong...

Hi,

Thanks for the reply, i agree that staying with shorter FL ensures better guiding!
What do you think of Barlowed Ccd imaging, newer tried that..

Best
