Hi Trevor, all you need is a T-1.25" adapter. There are plenty around. Try bintel or myastroshop. Any reason you want a 1.25 and not a 2"? 1.25 swill give you very bad vignettint

If the worst comes to the worst get one of these

hi paul the reason i need a 1.25" and not a 2" is my 6inch sct only has a 1.25" focusser thanks for the info very my apreciated

That's a shame. Why not look into a 2" focuser at the same time ;)

[TJD]

is it possible to put a 2" focusser in a nexstar 6se?

[[1ponders]]

Hmmmm doesn't look like it. You'll also have to take into consideration the additional weight the 450 will put on the back. What are you hoping to image with it?

Anything is possible with an angle grinder!!!!!!

Couldn't resist

Why not....Its only a celestron :P :lol:

I think the cheapest and easiest option might be to fit a 2-inch "visual back" to the rear of the scope. Bintel sell for $39 and typically stock these.

Bintel SCT - 2" adapter

This adapter threads onto the visual back of Celestron or Meade Schmidt Cassegrain telescopes allowing the use of standard 2" accessories. Uses brass clamping ring to hold your equipment securely but gently. No more gouged chrome barrels from overly eager visitors twisting your diagonal to get a better view. Also allows 2" accessories to be used directly behind Celestron and Meade focal reducers.
Length: 45mm

Cheers,
Jeff

I don't know if the nexstar 6se can have the existing visual back taken off Jeff. Isn't it like the ETXs ?? Be good if it could

[TJD]

i will be using it for imaging not taking near an angle grinder even though its a celestron.:P realy meade's are ok,espeicaly when there not yours:P

If you are imaging (thinking deep sky) then does your mount come with some means of tilting the base to turn it into a pseudo-equatorial mount? If not then you will be limited to around 30secondish for your subs due to field rotation in Alt Az mode

the visal back can be taken off also saving up for guiding scope eq6 pro mount and a celestron wedge my plan for the future is to put my dob on a eq6 then use my nextimage for guiding aslo i would like to mount the camera pigy back and get some constelation images thanks for the hhelp

ps:is this what you talking about if not will it work http://www.celestron.com/c3/product.php?CatID=33&ProdID=362

thanks

It would depend on what the visual back thread is, but if its the same as any other large SCT when yes it will

[TJD]

how do i tell if it is the same as a large sct?:thanx: for every thing guys

[[1ponders]]

It will be 2" across rather than 42 mm.



Don't blame me, thats how they measure these things :lol:

[TJD]

yes(hope its a good thing) :P the inside is 50mm or 2":eyepop::P across on the inside so will it work :D
