- 1rpd 30mm 80 degree ST80 eyepiece, latest version $95
Note: Photo is of older, unblackened version without bolt case, now $85.
2" barrel; 30mm focal length; 80° AFOV = 1.40 radians = a true ultrawide
Fully MultiCoated Ultrawide Eyepiece!!!!
48mm filter threads, blackened lens edges, plastic bolt case
Note: I'm out of the green 1rpd boxes, it will come in the bolt case.
Or you may choose to have me swap it into one of the smaller 1rpd boxes pictured, which does not come with a bolt case. I received more eyepieces than
boxes recently. It is not clear if my Chinese box supplier is going to be willing to send more to me by sea, and flying empty boxes from China isn't practical
while I wait for a sea shipment, or look to have some (likely different) boxes made here.

Yes, it's the same eyepiece, made in the same factory, as the BW-Optik competition sells.
Yes, it has 48mm filter threads, blackened lens edges, and a plastic bolt case, just like BW.
Additional items, features, and Quality Control checks which leave the competition behind:
- Includes 2 small microfiber cloth squares in a zip bag, different colors so you can know which one you kept cleanest.
Having this cloth handy keeps you from thinking a spot of the coatings flaked off...it's just an eyelash oil spot which
wipes off easily with these cloths.
- Permanently marked (engraved) with country of origin (China) as required by US Customs.
- QC checks on EACH EYEPIECE by a mechanical engineer (that's me), verifying:
- The chrome barrel must pass completely through a 2.000 inch go/no-go gage, and measure 1.994 to 2.000 inches on
a Brown & Sharpe dial caliper. Barrels which do not pass through completely, are replaced rather than relying on
2.003-2.005 diagonal specs, since a customer found a 2.003 barrel which fit his A-P diagonal but not his TV
diagonal. The factory has apparently fixed this, now shipping barrels averaging 1.996 instead of 1.998 as before.
- Cracked plastic caps are replaced. Not a huge deal, but still a nonzero failure rate, both detectable and preventable.
- No lenses or retaining rings are loose/rattling if shaken.
- The lens edges are indeed blackened.
- A 48mm Hoya filter screws on fully and securely. The barrel interior paint isn't seriously flawed.
- The coatings on the eye lens grade 97% or better; on the field lens 96% or better; combined average 97% or better.
This is a subjective and arbitrary scale as with coin grading, but the fact is that 1rpd sets aside a good percentage
(typically 10% to 30% of each batch) for a blem sale.
- Blemished boxes, tight bolt cases, etc. are swapped to be sold with blemish-sale eyepieces.
100% physical inspection and cosmetic grading is a lot of work, averaging 5 minutes per eyepiece, which adds up when
the quantity is hundreds. But it is superior to the alternative of "ship every box, and exchange or refund the unluckiest and
loudest customers". Following the policy of many other brands (including Astro-Physics and Tele Vue, for example) the
individual QC results are not disclosed. This is to avoid the price-raising implications of everyone wanting only an
absolutely top-graded sample, when all which pass QC are excellent and quite equal.
1rpd 30mm 80 degree ST80 $85 Unblackened version without bolt case; or slight blem of $95 version.
1rpd 30mm 80 degree ST80 $75 Slight blemishes of $85 version (all include 48mm threads now)

- 1rpd (1.25") P51 Fully MultiCoated Plossls: 4mm, 10mm, 15mm, more lengths eventually to come. $25 each IN STOCK
- 1rpd (1.25") P51 Fully Coated Plossls: 6.5mm 12.5mm, 20mm, 25mm, 30mm $20 each IN STOCK
- 1rpd (1.25") P51 Fully Coated 40mm Plossl $25; and 2x Barlow $20 (what a deal!!) IN STOCK
The above Plossls have a surprisingly narrow field, closer to 40 degrees than to 50 degrees, but they have extremely good resolution and contrast. The multicoated
ones especially, should be treated as equivalent to really good Orthoscopics, or even better than most Orthos due to the modern coatings. Plossls have better eye
relief than Orthoscopics of the same focal length, but in the 4mm you're still jamming against the eyepiece to see the full field, so having a 50 or 52 degree field
would give you little advantage over these. For anyone who cannot afford Zeiss Abbe Orthos, and that includes just about everyone, the 4mm and 10mm are a
steal for planetary work. The 15mm also is, except that by 15mm focal length you might be starting to miss having a wider field than these have. Still, binoviewer
folks love getting pairs of all lengths due to the quality and price.

Welcome to Astrobuffet, and also to 1rpd !!
Astrobuffet will continue to be primarily associated with retailing the unique lines of products it is known for, from exotic ARIES optical
accessories requiring a "special type of dealer", to military-spec cases for SCTs, to hand-made Baader solar filters to fit many scopes, to Hoya 2"
eyepiece filters. Having established several such specialty niches already, Astrobuffet will continue to add more of them.
We are expanding into selling some of the more traditional bread-and-butter product lines (scopes and eyepieces for instance!!) carried by other
astronomical-equipment dealers, now that more and more manufacturers, exporters, importers, and fellow dealers "know we're real" and are not
about to dump their products on eBay at wholesale as a non-profit favor to the public. However, there is still an oppressive amount of discrimination
against online dealers who choose not to open a storefront also. Let's face it, the largest "storefront" dealers do the great majority of their business
online nowadays anyway. Yes, the storefront model guarantees against someone gaining access with near-zero entry cost, but it's crazy to also shut
out real dealers who make their serious business investments more in tune with their own business model, rather than the camera-store business
model. My investment in this business went into 6 figures long ago, is heading for 7 figures at a frightening pace, yet there are several famous
companies that refuse to sell me even a windfall order such as $20,000 worth of diagonals at once, unless I pay retail and go through a dealer. Get
real! I'm done with pursuing business with folks like that.
1rpd was created in order to showcase those products which Astrobuffet will primarily sell via wholesaling to other dealers. These products are
initially going to be the types of products that I've had difficulty in obtaining "famous brand" dealerships for, and my target market includes both
other predominantly e-commerce dealers, a few respected specialty dealers who march to a different drummer, and traditional dealers who carry
many brands yet too few real choices. Astrobuffet will of course be a 1rpd dealer as well. In fairness to our dealer network, after introductory
pricing ends, Astrobuffet will neither undercut the prevailing street-price ranges which emerge from competition among other dealers, nor be singled
out for special treatment above any other dealers who get up to speed with selling the product. 1rpd will promote its products and dealer network
with marketing and advertising activities, separately from Astrobuffet's dealership marketing and advertising activities.
I expect that the 1rpd brand product line will be more important to non-storefront dealers, than it is to dealers who already carry all the usual
storefront-only brands. The non-storefront dealers, Astrobuffet included, will be very actively selling 1rpd products. I expect some to rank among
the largest 1rpd dealers, due to a level playing field and their lack of distraction from the lure of selling popular higher-priced, storefront-only
To date, I've not branded any products as Astrobuffet. Astrobuffet is just the name of my whole astro business, the domain name for this website,
and the business name for the tax IDs, EIN, bank account, P.O. Box, truck USDOT number, etc.
Today, Astrobuffet is best known to the public for being an Internet retailer who does some importing of exotic optical stuff, run by the guy who runs
the MAPUG mailing list. It will be best known to astro dealers as the business entity they will write their checks out to, when they buy 1rpd products
at wholesale. And it's already quite well known worldwide as the place manufacturers, dealers, and importers/exporters can turn to for quick
wholesale transactions in one direction or the other, for certain types of astro products, especially ARIES accessories, 2" diagonals, 48mm Hoya
filters, Gitzo carbon fiber tripods, large Chinese achromats, Plossls, etc.
In one sense, 1rpd is simply a way of leveraging my technical and importing expertise to become a wholesale supplier of products which I need for
my own dealership, and which other dealers are also capable of selling. In another sense, it's a bid to upset the apple cart of complacent suppliers
who have grown out of touch with the world market in astronomical goods, and have perhaps been thinking to themselves "If it ain't broke, don't fix
it" for too long.
One area where the Astrobuffet and 1rpd efforts will be combined, is by providing house-branding services to dealers and manufacturers. For
dealers considering starting their own house brand, or manufacturers wanting to complement their product line with products they neither feel like
manufacturing nor selling someone else's brand of, we can help reduce the time to market, and save the cost of mistakes you would otherwise make.
Well, the gauntlet has been thrown. In addition to starting the new 1rpd brand, a long-term advertising commitment was recently made by
Astrobuffet to Sky and Telescope. Expect a large flurry of activity, and maybe a little controversy, as Astrobuffet and 1rpd set off in quest of
changing the landscape of the astronomical equipment market.
Adding new ideas and a little more competition into the marketplace is good, right? If/when prices come down further on some of the goods I bring
to market at previously-unheard-of low prices, please bear in mind the good that has come to you from my foray. I'm sure that along the way, some
"entrenched incumbents" will undercut prices to a crazy degree to try to stifle the new competition.
(April 30 note: The above was prophetic. The big 30mm ultrawide eyepieces have dropped from their $195/$225/$295 prices a month ago, to just
$99/$225?/$295? after I announced a $159 introductory price which stepped on some toes and triggered a knee jerk reaction or two.)
I will do my best to meet or beat legitimate, advertised prices of competitors. But price competition alone can be undermined by dumping, predatory
pricing, or just a brunt-force attack of a larger competitor wishing to wage a battle of non-profit financial attrition. Bear in mind that a real price for
an item physically in stock ready to ship, especially if advertised in a major magazine, is quite different from any price associated with a removable
online classified ad, or any ad "taking names for a waitlist", "expecting some in stock soon", "limited quantity at this price", "call for best price",
and other games like that.
Right now, I'm not totally thrilled about shipping out my beloved 1rpd ST80 eyepieces at $99 just because a West Coast competitor thought I'd not
match his huge price moves on a competing brand well before he even had any in stock. But it's part of the business, so I've done it, and I did make
eyepiece sales to his normally loyal customer base who got tired of being waitlisted and hearing "two more weeks"..

P.S. Building the business has taken precedence over building my personal observatory, so you will notice some high-end equipment for sale. It is
brand new, having been imported a while back (when I had "a day job" rather than this 24x7 job!) to build my personal observatory, which simply
isn't happening anytime soon!
