Description

Super Plossl eyepieces from TS Optics: 6mm Focal Length

The Plossl eyepiece design has set a new standard for quality and has been in use for decades. Its popularity is due to the good performance at an unusually low price. TS Optics Super Plossls are state of the art Plossl eyepieces with outstanding optical quality. They are particularly well suited for observing planets and the moon. Their image sharpness and their high transmission makes them ideal eyepieces for many applications.

The TS Super Plössl 6mm ... a wonderful high magnification eyepiece, particularly suited for observing the planets and the moon. The eye relief is a little narrow, however this is not a problem when viewing the planets which only fill a small portion of the field of view. However the transmission and sharpness are a match for many more expensive eyepieces, and superior to many eyepieces with a long eye relief!

Quality Features of the TS Optics Super Plössl eypieces:

High Grade Multi-Coating	A special high grade multicoating on all glass-to-air surfaces provides for excellent light transmission, image clarity and colour fidelity. For further information on this FMC coating please see "user reports"!
Blackened lens edges	for suppression of stray light inside the eyepiece. This is particularly important when viewing bright objects
Rubber eyeguard	for better viewing comfort. The eyeguard also keeps stray light from the side out of your eyes.
Excellent value for money	The TS Optics Super Plossls offer a superb optical performance at a low budget. This makes them particularly suitable for beginners and also for demanding planetary observing.

A special feature: TS Super Plossl as projection eyepiece for photography

TS Super Plössls are very well suited for eyepiece projection photography. Plossls offer a large undistorted field. They can be used with most standard eyepiece projection adaptors, or if you have only a limited amount of back focus (especially on Newtonian telescopes) you can use the Fotoring T2 for the camera adaptation. For further information please see "recommended accessories"!

Specifications of the TS Super Plossls:

-- fully multi-coated
-- blackened lens edges
-- 1.25" barrel size
-- 1.25" standard filter thread
-- rubber eyeguard

A comparison of the TS SP 6mm and other eyepieces - by an amateur astronomer

I do not have very much experience yet, but I try a quick comparison:

In this night the seeing conditions were excellent (1-2 on the usual scale). The telescope was a GSO Newtonian 200/800mm.

The first eyepiece was the Antares 5.7mm W70. Already during a short earth observation I recognized its "nervous" viewing position. This was confirmed during plantary observation. Looking not exactly in the center of the eyepiece the border constantly came into the field of view. The fun of observation suffered noticeably. In addition the sharpness towards the edge was unsatisfactory. So away with it.

Next came the BAADER Eudiascopic 5mm. The viewing was noticeably smoother. In addition the sharpness of the image nearly up to the edges and the brightness were very good. I could easily recognize the Cassini division in the rings of Saturn. The moons were pin-point. The eye relief is good (no crawling into the eyepiece is necessary).

Finally I took the TS SP 6mm out of the the eyepiece case. Contrary to the first planet observations, with which I had been disappointed a little, the TS showed almost no weaknesses in this evening. The image of Saturn was absolutely clear before my eye. Cassini division and moon showed as recognizable with the BAADER. Image sharpness was almost as good as the Baader eyepiece. The viewing comfort is similarly good, only the eye has to get closer for viewing the entire field of view. In this evening I realized how important the seeing really is.

As an unprejudiced beginner I had actually expected substantially larger differences between the eyepieces. If I had to make a ranking, the ANTARES would be the last by far. The BAADER maybe would have earned the first place in terms of quality, but regarding the large price difference I would prefer the TS SP.

(My first thought about the eyepiece case was that it was a typical marketing gag. However, now I became aware how much money I saved with it.)

By the way, the impressions described above were also confirmed by my 12 years old son..

Transmission - A comparison between the TS Super Plössl and a TeleVue Panoptic:

For observing faint objects the transmission of an eyepiece can be crucial. It can also be important to know how much light is transmitted in each wavelength, i.e. which parts of the spectrum pass the eyepiece almost unhindered and which parts are largely blocked.

Inside each lens virtually no light is lost. The loss occurs in the transitions between air and glass, and the transmissions back from glass into air. To minimize this loss at the "glass-to-air-surfaces" an anti-reflective coating is used, but coatings can be very different in quality and effect.

We had the eyepieces tested by an independent tester with professional transmission testing equipment. Of course we cannot test all eyepieces available, but the eyepieces we already had tested allow us to do comparisons with other, untested eyepieces.

The spectral curve:

The transmission should always be judged based on the spectral curve. For example a high transmission in the red part of the spectrum is almost no use during the night, because at night the human eye has only a very low sensitivity in the red part of the spectrum. By contrast, the green wavelengths are particularly important because this is where the eyes are most sensitive.
.

Colour	Wavelength	% Sensitivity
Blue	450 nm	45 %
Green	500 nm	100 %
Yellow	550 nm	40 %
Red	650 nm	10%

This table demonstrates that a mere statement of the peak transmission without relation to the wavelength is virtually useless. An eyepiece might have an extremely good transmission in the red wavelengths, but in actual usage it might be very dim!

TELE VUE Panoptic 15mm
Peak transmission 88%

TS Super Plössl 32mm
Peak transmission 98%. Very good transmission in the green part of the spectrum
