That appears to be a 5" RFT.  Very portable and nice for large deep sky stuff, but a fairly specialized instrument.

Is that good of a telescope?  Sorry but heard of it, but didn't know it was that good.

OK here's a couple things on the topic. You can shoot the dumbbell (M27) but you will have to track the shot. With a 200mm and a 2x you are going to be shooting at f4+ depending on which lens you have. This is not a one shot object. You will need a couple hours of exposure as a minimum at f5ish. Take 1-3 minute individual shots and combine them with a stacking program.

One way to get way more luminance data to combine with the shot is a Hydrogen Alpha filter (probably about 12nm would be perfect) that you can stick in the camera. This would be huge for excellent detail but it will need a couple hours of exposure to. 

I'll stick up some of my astro shots and if you have questions just let me know.






I'm so motived.  Now I thought the hydro alpha filter was for shooting into the sun?
