I am looking for a smaller more portable mount for my AT80EDT to do some astrophotography with.  I would be guiding it.  I am currently using with a CGE but it isn't very portable and I am getting older.  Anyone have AP experience with the these little gotos they can share?  I need pros and cons.

 

Thanks,

 

JTS

I spent 5-6 months imaging with the 4/5SE mount until recently upgrading the mount.

 

The mount isn't very great for DSO's, but can work with a whole lot of patience. My experience is, maximum 30 second exposures (probably better to do 15-20 seconds), and be prepared to toss a lot of your exposures, depending on how picky you are. Using the 80mm might be more forgiving for you however.

 

Polar alignment is very hit or miss, obviously. A 6/8SE mount with the wedge may be slightly better. Also important to note that the wedge design likely prevents access some area of the skies near the pole depending on your imaging train.

 

Edit: I'm unsure about guiding, but the wobble factor and difficulty polar aligning very accurately might be problematic.

 

Like I said, you probably can make it work-- but at the end of the day, ask yourself what is your time worth to you.

 

It will work okay for planetary but expect some drift.

 

TLDR: coming from a CGE you are probably not going to find it acceptable.

A small GEM is best.  Something like an older SW EQ5 or Orion Sirius EQ-G.
