Hi,
After spending about a year taking pics with my pentax DSLR and a few different camera lenses on a RA driven EQ4 mount with no tracking problems, I took the plunge and bought an ED80. Out tonight to take a few pics of moon - very nice.
Turned to Eta C for a rough deep sky test - first pic 90sec exp had really bad star trails. Motors were running OK, counterbalance is approx 4.5kg.
Suddenly realised I didn't know the best way to balance the scope for photography!!!
Is there a method? If the weight is low on the shaft the scope overbalances to one side, too high the same. Can't seem to find a sweet spot.
Is the counterweight too heavy for the setup?
Any tips
Thanks in advance
Cheers
Doug
