Pentax SMC-XL 21mm
My most used eyepiece. Eye-relief is easy to set with the screw up/down adjuster. Views are clean and crisp right to the edge.

Great, bright views, Wide FOV. Premium look, feel, price. Screw-in screw-out eyepiece works great for 1-person sessions, but may take some fiddling if you're switching off with eyeglass wearers and non-wearers.

I have the 14 and 21 and both are superb. Since I must wear my glasses while observing, the 20mm eye relief is very nice and that is the main reason I chose these over the Panoptics. No regrets and everyone that looks through them loves them.

I recently acquired this eyepiece, and it quickly became my favorite eyepiece for use in my SCT. It has the perfect balance of light throughput, clarity, superb eyerelief and really comfortable to use. The unique pentax eyeguard is a pleasure to use and the big eyelens is great. I also like the size, big but not overwhelming. The best thing about these eyepieces is that they sort of allow you to forget you are looking through an eyepiece. Even the televues never did that for me.

Pentax SMC-XL 21mm
The weak link in the Pentax XL line, and still a very nice eyepiece. This is the smallest and lightest Pentax XL, which is good. Like the others it has great eye relief, contrast, light transmission and build quality. The eye cup works great. However, unlike higher power Pentax XLs, the 21mm shows significant edge astigmatism in F/5 or faster scopes, which can be somewhat annoying.

Pentax SMC-XL 21mm
Best 1 1/4" wide field eyepiece on the market. Views are tack sharp to the edge of the field, excellent contrast on DSO's. Equal in performance to the the 22 Panoptic, but better eye relief. Worth the price, especially if you wear
eye glasses.

Pentax SMC-XL 21mm
I was using two celestron ultimas on my celestron G8n with average results when I decided to take the plunge on a Pentax 21 XL. And WOW what a difference.Much brighter and sharper. Its like I have a new scope. Anybody want to buy two celestron Ultimas? Since then I also got the Pentax 14 SMC XL, and their both a ten. Even though I spent my grocery money for the next three months on them, I am happy. ( but hungry)

Pentax SMC-XL 21mm
Very nice mid power eyepiece that barlows well in an 8" F6 dob. Visually the view are great with good contrast and crisp detail to the edge. I have noticed that when I try to record the planets with a camcorder, the image comes out of focus as it gets to the outer 1/3rd of the view. I don't notice any problem visually. I do not have this problem when using my 35mm Ultima for camcorder recording.

Pentax SMC-XL 21mm
This is my favorite 1.25 " eyepiece. The best view out of my Pentax 80mm ED (24X) and bright sharp 57X views in my CR150HD 6" F8 refractor day or night.

Pentax SMC-XL 21mm
My most used EP after the 14mm. Like the 14, it's a bit massive but comfortable. The screw in/out eyecup is a bit loose but managable. Views are clean.

Pentax SMC-XL 21mm
This is my most used eyepiece, giving truly wonderful views.

An excellent series of eyepieces, all parfocal, all with wide field of view, and very high optical throughput. Eye guards are easily adjustable to give a deep well for viewing through, or flat against the glass for specatcle wearers.

Highly recommended.

Pentax SMC-XL 21mm
This EP is awesome! I have 12mm and 7mm Naglers and along with those, this Pentax stays in the scope most often! Pinpoint and bright stars to the edge. Zero distortion. Quality of this eyepiece is the absolute best! I have used on my Celestron 8" SCT, my 13.1" Coulter Dob, Clubs Meade 12" LX200, and son's 6" Celestron Starhopper and it brings out the absolute best in all of these scopes at all focal ratios and magnifications. This is a hard to beat jewel!

Pentax SMC-XL 21mm
This is one great eyepiece that works just as well in my 5" MAK as it does in my 4" APO. Too bad it is too large to be used in my binoviewer because it would be perfect.

Pentax SMC-XL 21mm
I have used the Pentax SL 21mm in my 140mm F7 apo refractor. The images are sharp and crisp on axis but get a bit soft in the outer 35% of the FOV. I can clearly see astigmatism in the eyepiece as stars approach the edge of the FOV. I am a big Pentax fan as I also have used and love the 10.5mm and 14mm eyepieces. The coatings are very good and I have never had any ghosting are annoying scatter around bright objects. While the 10.5 and 14 XL's do show edge distortion (like most any eyepiece if you look close enough) I have never considered it to be detrimental to the use of the eyepiece. The 21mm, however, has just enough distortion to become noticeable and distracting to me. I've decided to sell the Pentax 21 and replace it with a 22mm Panoptic. I already own a 35mm Panoptic and have been very pleased with it's sharp FOV. I'm hoping that the 22mm performs as well.

I prefer the threaded eyecup on the Pentax XLs over the click mechanism used by TV and I also find the XLs less prone to kidney been effects compared to TV eyepieces, especially the Naglers.

Overall, the 21mm Pentax XL is a good eyepiece just not as good to my eye as the 10.5mm and 14mm versions.

Pentax SMC-XL 21mm
This is one of my favorite eyepieces.
I'm currently using it on a TV85 scope.
The field of view is great, its nice and bright.
A great low to medium power eyepiece.
Great for deep space, or terestrial use.
The only downside I could see, is its size.
The picture is sharp thoughout.
Its a keeper.
