Reasonably-priced quality EPs
« on: December 27, 2017, 11:25:36 AM »
I've looked at ads for dozens of eyepieces over the past month or so, and some appear to be of obvious high quality and some don't. Obviously price is probably a pretty good indicator of the optical and mechanical quality of anything, but many EPs are simply too expensive for a beginner. What I am seeking are recommendations by the owners/users of good quality 1.25" EPs priced around $150 or less. I plan to use them with a Celestron 8" EdgeHD OTA, which comes with a 1.25" VB and diagonal.

The Explore Scientific 24mm 68 degree is a great eyepiece.

Don't forget the Astrotech and Sterling high grade Plossls which are currently being phased out. The Astrotech Paradigms are well regarded too and they are cheap.

Another vote for Explore Scientific. The eye relief is a little tight for some, but I find them very useable. Buy used if you can.

At $60 each, it is really hard to beat the Astrotech Paradigm's:

Also available at Agena astro:

http://agenaastro.co...na_dual_ed.html

These are excellent all around eyepieces with very good coatings.

The Meade UWA are on sale right now for $103. They are all very good but the 5.5mm focal length is the gem of this line:

The Flat Field eyepieces are also very good and reasonably priced:

The Meade Series 5000 UWA 82 degree eyepieces are similar to the Explore Scientific 82 degree versions and are currently on sale at some vendors.

The Celestron X-Cel LX, Meade Series 5000 HD-60, Astro-Tech Paradigm Dual ED, and Agena Starguider Dual ED lines all offer extended eye relief and a 60-degree AFOV at reasonable prices.

I have been very happy with any of my Explore Scientific 68* and 82* EP's. With sales and buying used, I have found a number of them new closer to $100 or for as little as $75 used.

I bought my ES68 24mm used for $100. It's a fine ep that'll product the widest FOV in your SCT with a 1.25" ep and give reasonable magnification too. Very highly recommended.

Last nite a friend and I compared a Meade 14 and an ES 14. Both were older versions. The Meade was huge compared to the ES, and the Old ES compared to the current model is also slightly larger.

I would also say even a simple plossl can be good if money is tight. Meade 4000 series are as low as $25 new. For the most part you pay for features like a wide field of view and eye relief. I have some great expensive eyepieces, but I still use kellners, plossls, rkes, and orthos which in general are under $60.

I should mention that these eyepieces can have very little eye relief in some cases. I use barlow lenses to help in those cases. Instead of getting a 6mm plossl I barlow a 12mm.

With the 8" Schmidt at f/10, it would be more "forgiving" of the chanced quality of the better-yet-less-expensive oculars. However, that's not to say to run out and get one of these...

http://www.bhphotovi...sory_Kit_5.html

Celestron will include a 1.25" 40mm(51x) Plossl with the Edge HD, and to be looked upon as a feeble attempt to satisfy wide-field dreams and desires with that type of telescope. If you're planning to equip the telescope with a 2" visual back and 2" diagonal, then a 32mm(64x) or 38mm(54x) 2" 70° eyepiece would be an option. Such would be one of if not the best way to squeeze out as much wide-field performance as possible, if desired...

http://www.universit...2inch.html#WS70

The same are carried by Agena Astro, but the 32mm is out of stock at present... http://agenaastro.co...roproducts.html

The exit-pupil of the 38mm, however, is only 3.8mm; the lower the magnification the better. I have a 2" 32mm 70° ocular, and illustrated here with a standard 1.25" 25mm Plossl...
Then there's the option of adding Celestron's .7x focal reducer, and for an f/7.1 focal-ratio. Now, wouldn't that be boss, but I don't know if a 2" visual-back might then be enabled. In either case, with the integration of either a 2" visual-back or focal reducer, or both if possible, research would be required, and a visit to the "Cats & Casses" forum would be in order.

Something-something in a 20mm to 25mm, and in a 14mm to 16mm, might be had, and for this and that.

The 8mm and 12mm AT Paradigms, or those of the AA Starguiders, come well-regarded, with accolades aplenty even, and with each containing a built-in barlow.

With a motorised equatorial, orthoscopic eyepieces are stellar performers in their own right. A 5mm, 6mm, 7mm, 9mm and 12.5mm should do the trick...
Choosing eyepieces and accessories for a new telescope is great fun, but only when accompanied by patient and thorough research.

Thanks for all for the recommendations. After doing more research, I'm leaning toward the AT Paradigms/Agena Starguiders. They appear to be quality, highly-recommended, well-designed EPs with reasonable prices, less than half that of the Explore Scientifics, also highly-recommended. But the sale Plossls at fire-sale prices are also tempting, if for no other reason than to fill in a few spots inexpensively. The limited eye relief is perhaps the major detraction for the Plossls. For the record, I can view nicely without glasses, so limited relief may not be a deal-breaker.

I will evaluate the reasonability of a 2" VB and diagonal after spending some time with the 1.25" apparatus for a while, Muse. At least initially I hope to keep cost to a minimum, but of course we all know how well that works with astronomy, don't we. The siren song of the next greatest EP or telescope always beckons. For example, I started out thinking that a 4-5" Mak on a simple alt/az mount would be just fine, but now I'm settled on an 8" SCT on a go-to GEM. And that was without spending any money yet. 

If I may ask another question, what focal lengths would most folks recommend for the first two or three EPs to be used with an 8" SCT?  I'm not looking for high power, rather just good clear viewing of the moon, planets, and some wider-field views of the night sky over the northern hemisphere in order to learn where things are. And I realize a telescope with a 2032mm focal length is not ideal for "rich field" viewing. But it will have to suffice.

Simply use this formula, which uses an 8" Schmidt's focal-length...

2032mm ÷ ?mm = ?x

2032mm ÷ 12mm = 169x, and in the case of the 12mm AT Paradigm.

This 20mm would be a good choice... http://agenaastro.co...w-eyepiece.html ...but read the user-reviews and everything else you can find online before purchasing.

2032mm ÷ 20mm = 102x

It has a 68° AFOV and should perform great with an f/10 telescope. I'd suggest the 15mm(135x), too... http://agenaastro.co...w-eyepiece.html

If I didn't have my "old-school" 20mm Erfle, I'd try it out in a heartbeat. Although, I'd love to compare the two...
