Just to clarify something for me: If I have an ST80 with a DSLR, will the combined weight work on a small tracker such as the Skywatcher Star Adventurer Pro?  I'm mostly playing around with what I have right now to learn.  I have the ST80 (and I have for it a very long focuser that gives me a lot of options using cameras), and I have a DSLR and I have a ZWO ASI462mc.  I also have a tripod with an 11 pound payload. 

 

I know, I know -- to REALLY get into it, I need a bigger mount and a different refractor. But is it theoretically possible to use my ST80 with an attached camera and the Star Adventurer tracking mount?

Should manage the ST80 and DSLR. Scope should be 3-3.5Kg, DLSR under 1Kg, So lets say 4Kg or thereabouts, 9lb.

 

Worst aspect is your expectations, also the time and attention to polar aligning the mount. In general the expectations are high, and the time and attention to PA low.

 

Scope will show CA, guess you realise that. DSLR will need an Intervalometer and some form of T-ring.

IIRC with my ST80 the focuser would sag a little with a guide camera on it.  A DSLR would of course be heavier.    But you can definitely try it out and have fun.

This has been my experience and caused me to upgrade the focuser on my ST80.  I started imaging using an ST80 and the color aberrations and coma were horrible, but it was the only thing I had at the time.  Here are a few shots when I was using it.

Go for it. Learn through experience, that is the best way!
Those shots are nice and really stimulate for more I would say.

StarmanDan, I would be thrilled to do those shots through my ST80!

 

I bought this ST80 off here a couple of months ago and it originally had a very long focuser on it, and had been used as a guidescope. I got a standard ST80 focuser, flocked the tube and put it on my NexStar GT mount and use it visually, but I sort of think that long focuser could come in handy if I used it for photography.

You might be able to put the Nextstar GT on a wedge and get the benefits of an EQ mount. I am not sure if the GT software has an EQ mode, but this old post seems to indicate it does.

I put my 80mm F/5 and a DSLR on a $100 entry level EQ mount, which I motorized myself and added RA guiding.
