Hi Jowel,
I have an 8 inch Skywatcher Black Diamond reflector (solid tube) on an HEQ5. Still has the new scope smell as I only bought it two weeks ago.
Check out my first attempts at Astrophotography in the Beginner's Astrophotography forum
here.
You will see pics of M8 - the Lagoon Nebula, M20 - Trifid Nebula and M22 - Globular Cluster, all taken with a Canon 1000D DSLR (about $900 now) which was screwed onto the focuser with a T- Ring adaptor.
No guiding used (that's coming later), no fancy control, just the mount aligned and a handful of 30 second exposures stacked to provide better data.
Whilst I have done a bit of capture of planets with a webcam, this was my first red hot go with a proper mount and capable scope for deep sky stuff, take a look and see the results of me starting out. Not in the big leagues yet as this takes a LOT of practice, but I am quietly pleased with the results from only 1-2 hours of playing in the back yard in Suburban North West Sydney.
If you go for the solid tube Dob, then yes, putting this on say an HEQ5 later will be a doddle and you are on your way.....
Cheers
Chris
