Max size eyepiece SW skyliner 200p

[stuffedhaggis]

Hey guys

I was trying to figure out what is the max size eyepiece I can go to on my 200p. I have a 4mm

Simple answer: Stick it in and try it.

You have the scope and you have the eyepiece, just give them a go.

I will bet that if people say not really that you would go ahead and try it anyway.

Without trying it the answer is possibly.

It wil be towards the limit of the scope and will depend on the eyepiece.

If a plossl then I suspect it will be poor to very poor, you will also be almost wearing it like a contact lens.

If it is a planetary then more respectable results.

If a nagler, ethos, delos then better again.

I think the 4mm is propably pushing it and you will need to have excellent viewing conditions to use it effectivley.

But then again I'm new and probably wrong

A 4mm will work some days and not on other's just depends on the "Seeing condition's" , i have a 5mm for my scope most of the time its not very sharp, but on the good days viewing Saturn you could count the rings, Global Clusters they look like you could touch them,,,so if its affordable go for it.....

Personally I think with our skies in this country about x200 is about the limit. If your scope has a focal length of 1000mm f5 then you will get x 250 or if it is a dob f6 then you are looking at x300 which for me would be pushing it a bit. But as Capricorn says, chuck it in and give it a go.

I go down to 7mm on the 200 Skyliner. Fast Newts are very harsh on EPs. However , the main consideration is seeing conditions.

You've got to figure that with high mags, you've got to manually track the scope.

Fast scopes are harsh on some EPs and not others. BST (sometimes called paradigms) work very well in fast scopes, as do volcano top EPs(Circle T etc) orthos.

I find 4mm too much for my 200P. 8mm (125x) max though sometimes I can go down to 5mm (200x).

+1 for 5mm ,but if it works with 4 ... go for it!

With the atmospheric conditions as they are i use a 15mm npl with a tal 2x barlow, this seems to work for me. until we get clear cold nights then i will try 5mm.
