4.8mm Nagler

Hi all

I've been on the lookout for an eyepiece in the 5mm bracket, to help split tight doubles and wasn't sure what to for. I saw an ad on Cloudynights for a 4.8mm Nagler, type one, here's an image of the eyepiece:

This is an older eyepiece, the seller was asking $100 and $10 to ship it, less than €90, I couldn't turn it down.
The seller has put it in the post and should be here in a week or so.
Looking forward to its arrival and I'll let you know how it performs.

Good luck with it when it arrives, I bought a 9mm and 16mm Nagler a while ago, no regrets
bought them second hand also, hope it performs well for you

The eyepiece arrived this morning, tomorrow night I plan to be at the Sandymount observing session, the weather is promsing good, so it should get a workout.

Great stuff, Paul. Now blow us away with it. Liam Smyth issued me with a challenge recently. Split Almach (Gamma Andromedae)into 3 components. I haven't had a chance to try it yet with the 158mm APO. But then again, it might require a 3 mm Radian.

It would appear to very difficult object until another two decades or so. Good luck with it.

Goodness me, John. They truly are closing is on one another.

Thank you for the information. I do seem to remember splitting B & C sometime back in the 1980's with 300X in a very new 6" reflector. But I am not sure about that. I wonder was it possible back then.
