Long dovetail for Skywatcher 72ED

[Dougie Smart]

Hi All,

 

I have ordered a Skywatcher 72ED with field flattener which will arrive in the next few days.

I have heard that for astrophotography that a longer dovetail is recommended for this telescope to make it more stable.

As such,  can someone advise me on whether a 21cm or 33.5cm Skywatcher dovetail would be the best fit for this rig?

Hope someone can help.

All the best,

Dougie

On the FLO website, have a look at the ADM vixen type universal dovetail reviews, someone has recommended the 11" dovetail for the 72ED. HTH

I have a 21cm skywatcher dovetail fitted on my evostar 72ed ds pro and when I have my field flattener and dslr on the end I have about an inch of dovetail left and balances fine for me, so it's much better than the short one which isn't a lot of good but can still balance upto a point but so so close to the edge of the dovetail and a bit iffy in my opinion.

8" works well on my ED80, even with DSLR, flattener and filters

But maybe the 12" is more versatile assuming it clears your focuser and lens hood.
