Just looking for a little help with mounting this newly acquired 10" Meade SC. I'm using a Sirius EQ-G and I know I can just attach a dovetail to the losmandy bar and mount it that way but this losmandy bar is pretty heavy. Does anyone know a lighter weight way to go about this? Or is this pretty much the way its done.

farpoint and adm makes a vixen dovetail for the 10" meade but there is only 1 bolt on each end holding it on.

I would not mount a 10” SCT on a vixen rail - you’re underestimating the forces involved on the clamp, as well as relying on just two small bolts.

Sure it can be done but I’d describe it as perilous.

Agreed. I have several de-forked SCTs and the largest that I would put on the lighter Vixen rail is an 8", I use the much heavier Losmandy D rail for my 10" and larger SCTs. I bought a Vixen rail for my first de-forked Meade 10", but I couldn't imagine hanging all that weight on 2 slender bolts, so I never used it.

The D rail is heavy, but it does a great job holding these large scopes.

Good to know. I was worried about it being too heavy for the Sirius mount but actually it was tracking really good tonight, surprised me. I attached a modified dovetail to the losmandy with 4 bolts.

Yock1960 (solar system imaging forum) uses a C11 on a Sirius. If you pay close attention to the balance you should be okay.

Enjoy!

If it's a newer Sirius EQ-G (with Dual Saddle) I'd use the Losmandy Dovetail shown.  You can use a Vixen and save some weight but it's not worth the trade off's IMO.

Nah not the dual saddle. I just found out its actually 1lb lighter if I just use my 10" tube rings rather then the losmandy.

Coolness. To shed a little more weight you could also remove the radius blocks.

 

Enjoy!

Now you can donate that old Losmandy plate and radius blocks to those of us who need one, like me! grin.gif

Great. It's always good to have another robust option.
