I just got my first view of the 1st. QTR moon last night with my WO BV at is was great. The entire disc just fit nicely in the FOV of mt 26mm SP EP's @ 60x.
A very sharp view for sure and can't wait to use it on Jupiter this fall

Shorten the tube by about 1", or change the focuser.
I am using a Mark V (123mm light path) and a T2 prism (40mm of light path) and can reach focus with all eyepiece pair.
A standard 1.25" diagonal will have a light path that is about 70mm to 75mm, and a WO or similar will have a light path of about 110mm, so this is about 185mm vs 163mm or so for my configuration.
This means that you would need maybe 22mm of in travel to be similar.
I believe that the shorter focuser is over 1" shorter.
This is in one of the treads on the refractor forum regarding this scope, but I forget which one.

I'm talking about the Agena GSO Dual Speed Crayford 10:1
It states this as the length of it from the base of the scope to where the 2" EP or diagonal inserts.
Minimum focuser height (without 1.25" adapter but with base flange) = 111mm (4.37”)
I measure the stock R & P focuser that came with the scope and I get 4.5" length. Adding the 1.25 adpt. is 5"
So I'm not really sure if upgrading the focuser is going to give me the additional back focus I'm going to need with either the 1.25" WO BV set-up or the 2" Denk set up? I don't mind upgrading the focuser overall, but don' want to spend a bunch more on another diagonal/prism and more adapters.
Then there is whole other option of using my 80ED to BV instead of the 102g all together. Just would like to be able to use one of them as a Grab'n Go scope with the ability to BV as well.

It is in one of the long threads abuut th2 102. One of the threads is something like 45 pages and the other is something like 16 pages.
I forget which one it was in, but it was near the end.. Within the last 5 or 6 pages I think.
I can't remember if they were using WOs or Maxbright though.
Anyway, the details are there. Was not my scope. I cut mine.

I guess this is the only way short of cutting the scope. If I use the Denk 2 in it I'm going to have 2.3x OCS which is quite a bit more then the 1.6x...well that's straight through. With the reducer arm in place it get a lot less, down to 1.3x.....so decisions, decisions.
So do I keep both and just use the WO in my two refractors and the Denk in the SCT and 10" Dob or sell the WO and use the Denk in all e scopes?
