ED80 Equinox on a HEQ5 Pro, which dovetail?

[biondi]

Hi,

Could anyone recommend the correct dovetail to mount the ED80 onto the HEQ5 Pro please? I used to have a C8 SCT and still have the CGE Dovetail from that but I don't think this is ideal for the ED80 as I can't (safely) get it far enough forward to balance well (with a dslr on the back!).

Cheers!

I don't use one with mine. Mine has the little foot that I just use in the mount head and screw it down. It has never moved on me even with all my equipment in my sig.

Thanks nmoushon, can you get the OTA far enough forward to balance with all the stuff on the back?

[nmoushon]

It not perfectly balanced unfortunately. It close though. I know its not perfect that way and some really shy against it but I can get 2min subs unguided and an easy 5min sub guided. I havent tried for longer subs than 5min as the hot summers dont do well with my DSLR. I might go for a saddle plate if I ever try for 10min subs but theres a lot else I could do also. If you are going to use a a CCD and filters then you would need a saddle plate. I've never had it slip even at the zenith. Just a not I always have both screws screwed in very tight and both touching the foot. I would never try with just one screw touching the foot. Thats just never a good idea.

William optics 90mm rings and a Vixen medium dovetail should be fine.

Hi dmahon, are you referring to the ADM style dovetail? I have the below ad it looks a different shape slightly (not flat):

I was thinking Skywatcher, but yes. That one you show should work fine with rings bolted to it that fit the scope.

+1 vote for dmahon, the WO tube rings are really 1st class, there are lower priced versions that will do. I have the same dovetail as the picture and to spread the rings on the OTA, needed to drill and counterbore the dovetail to suit.

Dead simple with a pillar drill, much more difficult to control without..

I agree...aluminum is very easy material to handle.....i modifade my SW dovetail also, to correct balance.
