Hi Roger,

I am happy with my Opticstar 80mm F/6.3 APO forwide field imaging with CCD and DSLR. Here an image of C/2014S2 taken with this budget OTA. The DSLR needs a field corrector to cover the bigger chip than the CCD.

For around £450 you can get a new William Optics 71ED (71mm f/5.9). I have the predecessor of this, the Megrez 72, which is a 72mm, f/6.0 ED. I took this to La Palma recently and it works well with a DSLR and a SkyWatcher field flattener (see attached full frame APS-C pic). It's a nice, portable, well-made scope.

Lots of good second hand refractors come up on UKAstro Buy/Sell. A number of people seem to buy stuff and then "upgrade" so there are always good second hand bargains to be had. There's currently a ZS 66 for £250.

Nick.
