Denk in my Refractor
Posted 15 October 2013 - 10:02 AM
I'll explain...I have a WO BV for a couple of years and recently picked up a new Denk2 with the power switch at the NEAF show this year. So originally to be used in my 8" SCT and now learning all the other stuff about light paths and aperture reduction and so on. It has a 2" nose piece and had not stuck it in my 80ED yet that I use with 1.25" EP. For that I have been using the WO with the 1.6x barlow and it works well on the brigheter objects and nice on the moon.
Over the summer I picked up a 10" Dob and a 102g refractor that is 1000mm f/9.8. So I wanted to try it in the Dob, but I had to buy an OCS from Denkmier to get it to focus. It works well with the power switch. Really nice views of the double cluster with the reducer arm in.
So what about using it in the refractor and do I need two BV after all? Thing is, the WO is much lighter than the Denk and do I really need the power switch for casual views of the moon and planets with the grab n go 80 or the 102g? The mount I have is about at it's limit with all that weight and counter weights with the BV in them. Besides, I don't want to have to buy another OCS in 1.25" mode to fit the fractors.
Anyway, going back to the denk site to price one and kept reading bout the different ways to use them in different scopes. Then it hit me, just take the front OCS out of that long 2" tube and screw it into the front of my 2" diagonal and try it that way. Besides, the 2" way is more secure than then the 1.25" way. So got it set up and pointed it at a house roof a ways away and kept racking out the ring and pinion focuser and low and behold it came to focus! It was pretty dim in the 20mm EP's I had in it, but figured it would be ok on the moon tonight for a try. Then I tried it with the reducer arm in....ah, much better and brighter!
So now I might have the solution to use the Denk in all 3 types of telescopes I have. Just wish the Denks with the PS wasn't so heavy....oh well, perhaps I worry too much! If I think this will be ok, then I'll finally sell the WO as I don't need two BV and all the $$$ tied up. I'll just go with the lightest EP's I have.
So a question out there, the barlow used in the WO is 1.6x and I'm not sure what the multi purpose Denk OCS is, anyone have an idea? I hope it's close to the WO and under 2x?
I'm going to do the acid test tonight on the moon with all three scopes and both BV...who knows, maybe the WO beats the Denks???
Lot's of fun with all this bino stuff to learn

That's all easily found on Denkmeier's website under manuals...

This way you may be able to use the binos with no OCS for the widest possible FOV and it saves weight.
I know Denk do a dovetail connector for this sort of thing, if you give Russ a call he will let you know what will work for you.
The standard OCS is probably around 2x.
Precise Parts can also fix you up with a custom made connector if need be.

1,300mm, 2,300mm and 3,300mm vs. 1,600mm with the WO BV then?
So bottom line then is the Denk with reducer gives me widest, lowest power option with any BV at 1,300mm. Only way to not use the OCS then would be to spend a lot more money on prisim and adapter route I guess. Not what I want to do...spend a bunch more $$$ on this project as I already have.
Thanks for your inputs:)

Got to say I don't really use it or much as I prefer the view through my ES 40mm 68º eyepiece for wide viewing.
