Product Description

An excellent premium-quality low power wide field 2" eyepiece for the serious deep space explorer. The calculator below will show you just how wide the field will be with your particular telescope. For example, it will give you a 0.92 degree field at 74x with a big 17.5" f/4.5 Dobsonian. That's almost two lunar diameters and is ideal for observing large emission and reflection nebulas and nebula remnants.

While it's particularly well-suited for use with Dobsonians (it provides a huge 6mm exit pupil for rich field observing on an f/4.5 scope), it can provide "picture window onto space" images with any telescope type that can use a 2" eyepiece. With 16mm of usable eye relief, the 27mm Panoptic can be used by eyeglass wearers with almost no vignetting of the field of view. The 27mm Panoptic would be a welcome addition to any serious eyepiece collection.

It weighs a substantial 18 ounces, so you may have to do a little scope rebalancing when you use it with some low friction Dobsonians.

Panoptics nicely fill the middle ground - Well made, sharp and contrasty, but not over-the-top expensive nor overly heavy for their focal length. I've found the 27 is usually about as low as I want to go but it still delivers as much contrast as can be expected a low power. The 22 and 15 (older revs) perform likewise - sharp and clear with reasonable eye relief. In a day when $700 eyepieces are not uncommon, I find it difficult to justify going "above" a Panoptic.

I use this with a TV NP101 F5.4 and it is sharp with deep contrast an you can just lose yourself with this EP on those nights you just feel like exploring. If I decide something requires a little closer look I just drop in the 19MM Panoptic and get nearly the same experience with a little more generous eye relief. These both are always with me!

If you have an 8 inch SC with the focal reducer this is a great wide field eyepiece. Paired with the reducer the field stop is sharp with no vignetting. I have used this with an F/5 12.5 inch dob as well and it showed excellent edge performance as well. Additionally its weight is not so much that you need to change counterweights every time you remove it. (Posted on 1/5/2019)

I have owned this eyepiece for a couple of years now and it has been a steady performer. Sharp views right to the edge. This is the first eyepiece I use when visual observing. The eye relief others have reported doesn't bother me since I use a Dioptrix and don't need eyeglasses to observe. (Posted on 12/30/2018)

The eye relief is noticeably less than Radian or even T4. I have no problem, but I don't wear glasses. Kids at outreach need more help with eye placement before the "wow" for daytime solar than for night time views.

The outstanding aspect of this eyepiece is the sharp view across the full field in an f/6 refractor, a stunning way to scan the Milky Way, and something I didn't see when trying a couple of modern competing 68 degree eyepieces and an older 'classic' wide angle eyepece in the 24mm - 32mm range.

It's great with a Paracorr in reflector, too, and not too hard to balance, plus this may give an exit pupil that keeps sky a little darker than longer and heavier eyepieces.

At about 75x and 0.9 degrees in an 8-inch SCT, this makes a good deep sky or crescent moon eyepiece too. (Posted on 8/4/2017)

Very sharp and contrasty right out to the edge. It barlows very well. Its pincushion distortion has never bothered me. The main downside to this eyepiece is the lack of eye relief. It has about 16mm of usable eye relief due to the deeply concave eye lens. If you try to push into it to see the field stop, you will inevitably scratch your eyeglasses on the edge of the top retaining ring. That is the main reason I don't use it as much as I had hoped I would. (Posted on 8/4/2017)
