Hello astro-friends,

as we speak, we can offer the following OTAs and Accessories, from stock or with short delivery time.

102mm f6.3 - oilspaced triplet
2.5'' Moonlite DC electric focuser, 114mm travel, 180mm back-focus, rings, hardcase.
This is 'a special unit', my own personal telescope, that features a .99 Strehl lens, aspherized. It is the last one from a batch of 20 lenses.
Price 2090 Euro/ 2612 $ - personal sale.

This is the best 102mm lens on the market. Period.

127mm f7 Aspheric - oilspaced triplet
2.5'' Moonlite focuser option, 114mm travel, 180mm back-focus, rings, hardcase.
Price 3710 Euro, including 24% VAT (2990 Euro netto) - available on stock.

127mm f7 Aspheric - oilspaced triplet
3'' Starlight FT focuser option, 89mm travel, 180mm back-focus, rings, hardcase.
Price 3990 Euro, including 24% VAT (3218 Euro netto) - available on stock.

The above are using Schott Fluorite-like glass, are hand polished in the final phase for a smooth finish and high Strehl ratio. Typical Strehl is .98 . One surface is aspherized for best focus of yellow-green light, where eye is most sensitive.

These lenses can easily handle a magnification equal to three times their aperture in mm (as example, the 127mm f7, above 350x), when atmospheric condition allow it.

160mm f6.5 Aspheric - oilspaced triplet
3.5'' Starlight FT focuser option, 114mm travel, 180mm back-focus, rings, hardcase.
Price 8990 Euro, including 24% VAT (7250 Euro netto) - available at end of June.

160mm f6.5 is built around an FPL53 core, hand polished just as all our refractors are, aspherized.
Coatings are multi-layer type, with 99.5% transmission, for all refractors.
Pictures of all OTAs above, can be found on the website!

Field Corrector for 160mm f6.5 - 435 Euro, including 24% VAT (350 Euro netto).
*all our OTAs can be used for imaging with 3rd party reducers/corrector as long as they are designed for aplanatic objectives - free of coma - as our objective lenses are*

From Autumn 2012, we will have very affordable Cassegrain and Ritchey Chretien OTAs, quality proven with Interferogram, CF truss or CF tube construction.

As we are making OTAs, one by one, in case the mechanics are not produced, we can take special orders in terms of back-focus, color, accessories.

Everything we do is made in Europe and we are an OEM!!
For USD prices, please multiply the netto price with the exchange rate.

Thank You in advance for Your interest!
Catalin

Hi,

Clear aperture: 180mm
Focal length: 1260mm
Minimum Length: 1090 mm
Maximum Length: 1370 mm

With 1st trimester of 2013 we will have available 140mm OTAs with f6.6 and f7.5 focal ratio. FPL-53 based like all our lenses with a very nice and smooth wavefront.
Target price is 5990 Euro, with VAT, including rings and hardcase. Price for outside EU countries - 4830 Euro.

From time to time, we have 'specials' as we receive scopes back for upgrades from former clients. Please ask and I'll gladly inform what is available.

Thank You!
