Hello everybody.
A while ago I bought a motorised tracker and have been using it with my EOS 600D for moon photography. Unfortunately, the bug has bitten and I am now looking to move into planetary photography.
I have acquired a CCD camera for this purpose and am now looking at refractors.
I have my eyes on the Skywatcher Black Diamond 120/1000 OTA but have also seen an ED100-PRO for about $150 more.
So the question really is, would it be better to have the 120mm/1000 or the smaller 100mm/900 APO? Are the optics on the ED significantly better than the BD to justify the extra $$?
I appreciate any insights to save me from getting the wrong one!
Thanks!
