Orion Sirius Plossl 40mm
For $60 this eyepiece gives you the widest field possible at 1.25". Very good "finder" eyepiece.

Much too long eye relief. Hard to hold the view. Very bright images, stars are sharp almost to the edge of field. Odd distortion or ghosting if eye is not lined up perfectly. Decent finder eyepiece, others can easily beat it though.

No complaints from me on this eyepiece. It was my favorite Low Power eyepiece until I fell in love with the Naglers, Panoptics and Ultra Wide Angles. I would reccomend this to anyone with a 1.25" focuser in their telescopes.

For the money, this is a very good 'finder' eyepiece. I actually prefer this eyepiece to the Orion Sirius 32 as a finder eyepiece. The real FOV seems ever so slightly larger, and its just as easy to hold the view (IMO). Yes, there is some tendency towards occasional blackouts, but the same is equally true of the Sirius 32. Its easier to take in and see the field stop on the Sirius 40.

I like it. Awsome wide views for a good price. By far my favorite wide field EP. Sharp to the edge and contrasty even in mag 3.5 skies.

This is no match for the super wide field eyepieces everybody loves neither is it's price. I find images crisp and FOV excellent. In my opinion dollar for dollar the best buy I've ever found. While the $350.00 and up wide and super wides are better the cost difference throughs the balance in favor of this eyepiece. It's my favorite.

Bright, sharp, flat views makes it a good finder (e.g, 1.35deg actual field of view with 5"/f10 SCT), low magnification ep. On a performance/cost basis, it is a bargain.

Great eypiece for the money. With a 90mm apo-refractor of 1000mm, I was able to get a nice glimpse of Andromeda in so-so skies. Your not going to find a better deal on a low-power 1.25" eyepiece.

I like it. Haven't noticed any "distortion". Seems to work great in either the 10"SCT or the ST90. Well made and considering the price, a good deal.

Many of my problems with this eyepiece are probably due to the 40mm design in general. The contrast of the images is not very good. It makes finding galaxies difficult. The sweet spot is small so getting a full image is difficult and blackouts are common. I don't use this eyepiece much at all. I have a meade 32mm superplossl that has superior contrast and virtually no blackouts. I commonly use the 32mm for the purpose that i got the 40mm. Why doesn't orion give you end caps or a case for the eyepiece. Many eyepieces i have purchased for half the price or less provide them. I don't recommend this unless you can get it on the used market for far cheaper.

Good 40mm but I would recommend the 32mm over this one any day. The 32mm has only a very slightly less true field and better contrast due to the higher magnification in my C8. Eye relief for me is not at all hard to hold. My other problem with it, which is more ME than the eyepiece, is the field stop isn't as sharp as I'd like it to be. Again, check out the 32mm before buying the 40mm.

Works well just like the 32mm but with a smaller Ap FOV.Good finder eyepiece in scopes with only 1.25 focusers.

Orion Sirius Plossl 40mm
In a long focal length telescope (maksutov or refractor) the stars are pinpoint across the entire field. The views are clear and contrasty. The eye relief is good; allowing one not to have to get too close or too far away.

The optical limitation is that it would be nice if this could have a slightly larger apparent field of view, say around 50 degrees.

The value is very good, only slightly exceeded by the phenomenally low price of various RINI eyepieces which are only slightly inferior in optical quality.

I bought this eyepiece new to go with my 4.5" reflector a few years ago. It is a good eyepiece. Image quality is very good except at the very edges, and it shows little chromatic aberration. The 1.9 degree FOV is good for hunting down comets and DSO's, although more FOV would be nice at times. This eyepiece is a very good deal for a wide angle eyepiece for somebody on a budget.

*Update* 9-16-2002
I am using this on my XT10" until I get a TeleVue Panoptic 35mm. It has performed quite well on the XT10, showing little to no coma (which is probably in part due to the excellent optics mine came with). I have no complaints about it. I would definitely recommend this, or the 32mm for anybody wanting a wide angle eyepiece on a budget.

A decent eyepiece for the money.
It dosnt compare to a ultima, tv, or many other really good plossls.
Id recommend to a astronomer on a budget, it will give you really good quality views. Yes there are a lot better eyepieces out there, but they are a lot more expensive, this eyepiece will work a lot better on slow scopes of f10 to f6,because of the exit pupil dilemma of 7mm & below.

Got some of Orion's big glass? Need a really convenient finder scope? Not that dreadful thang that came with your Dob or Mak/Newt?
This is your baby!
Plus, pop on Orion's 1.25" broadband neb filter and for about a hundred bucks you've got a workable setup for moderate deep sky! It ain't a Mewlon 250 on an NJP, but hey, you'll still have 15 grand in your pocket!
