Circle T Kellners

[Stu]

Hi,

Just wondering if anyone knows much about these? I picked them up when I purchased an old OO SX250 sometime ago, a 40mm and 9mm Circle T Kellner. They are optically in very good condition, the 9mm has a little bit of scratching on the top but generally both good. I know 40mm in a 1.25" has it's limitations in terms of narrow field of view.

I will probably put them up for sale, just looking for some info before doing so.

Cheers

They were made at the same place as the Kokusai circle T ortho`s, i had the 25mm and i have to say, i was sorry to sell it, very sharp, but i bought the 25mm ortho and it was my most oversubscribed ep size, i still have at least 3 different 25mm ep`s. Have a look through them stu, before selling them

Thanks Jules, will do.

Trouble is, I have a 9mm BGO, plus 31T5 Nagler so they are most likely surplus to requirements.

Will give them a try out though

Cheers

On a semi related topic, I've just picked up an Orion Circle T 12.5mm Ortho. I'll be interested to see if its any good. Looks in good condition, might work well with my PST.

The Cir T Volcano Tops are all excellent IMHO .....bung one in a newt and have a cruise of some deep sky objects that are diffuse and you will likely be srpised at hist how good it is.

Thanks A_B. Bit short of Newts until I get my SX250 sorted but will try it in the 106mm, would give x55 in that, or a rather feisty x320 in the Mak on a very stable night :-)

Hi stu

If you decide to sell the 40 mm kelner give me first refusal please.

Hi Stu, did you ever try these kellners out

Hi Stu, did you ever try these kellners out

As ever, skies didn't co-operate in the end so I sold them before trying them unfortunately. I think Dave (f15) may have bought one if I remember correctly...
