Eye peace's with threads

[mlwood37]

I got a un-named 7 to 21 eye peace were you take off the eye cup and your left with a thread that i can attach my camera too.

Now im after a few more eye peace's like this a 4x and maybe a lower mag one. Any one know of which eye pieces can so this

The only ones I know are Baader Hyperion and this could be a clone. I do not think it is standard practice for eye pieces to be threaded in this manner. Baader supply all thread accessories to attach various cameras for afocal photography

The Revalation / GSO 'photovisual' 32mm possl allows connection to camera with standard T - ring and camera specific adaptor ( which I think is the larger metal item in your photo's? )

We got ours from this site & he does a handy little video explaining as well:

It's a highly recommended 'budget' EP, so probably better quality than the unbranded 7-21 you have.

I think you could have one of these http://www.opticalvision.co.uk/astronomical_accessories/eyepieces/sky-watcher_7-21mm_zoom_eyepiece__1.25-31.7mm_format

Pentax XW have a 43 x 0.75 mm thread under the eyecup.

As said, Pentax XW's and Baader Hyperion's have the 43mm thread and they do work well, on a stable tracking mount.....

thks every one. ill have to save up the whole set up above came to about £50 and does the job for a learner. Better to pay little and learn a lot. then pay a lot and lean a little. I can go stright to 2" but i don't know if that will make any difference.

The eyepiece you have is the 7 - 21 mm Skywatcher, but sold under a load of different badges - I have one

Also sold under the name of 'StarGuider' by Sky's the Limit, quite a good budget zoom in my opinion.
