FSQ106ED safe with Hershel Wedge with no ERF ?  or Quark for that matter.

 

Probably been asked before but as my interest is heading more planetary than Deep Sky , 

Not using the 106 so thought I'd try it on Solar.

Actually got a used SV110 as I didn't want to risk the Tak.

 

The Wedge i have is the Baader 2".

 

Appreciate any comments

I have used the Lunt 2" Hershel wedge with a TOA130 and no ERF.

Just the recommended ND filter installed. It all worked well.

But I'm not sure about the optical elements in the FSQ106ED nor the Baader wedge.
The TOA is just a triplet so things might be different with your Tak.

And in the very old days I have used EP projection onto a screen with a full aperture 8"F7 Newtonian without melting any EP's or telescope components. It did run a bit hot though. This technique even showed the solar granules on the screen quite well.

 

Besides if you are not using your FSQ106ED why not sell it for a dedicated H alpha scope?

Hi,

 

It will work fine with your 2" Baader wedge.

 

Very best,

I’ve used the Baader 2” Herschel wedge on my TSA-120 no problem

Thanks for the feedback , the difference is the FSQ106 has the built in field flattener Petzval design so a Quad lens setup. F5

 

Not sure i'd get any better result with the Quark than the Stellavue 110  F7 and its a much lighter scope.

 

I have just bought a used dedicated LS80T Lunt and might just sell the 106 as my interests have changed more to planetary and some EAA. I just don't have a good location for deepsky.

 

As always appreciate all the replies,
