Telrad - Dew Shield - 2025

by Telrad
SKU 2025


Telrad Dew Shield + (w/ mirror for 90 degree viewing)

Straight through sighting with viewfinders is great until you have to look at something near the zenith. Then you have to get under the finder and somehow look straight through the viewfinder, or in this case, the Telrad Reflex Sight. But fear not, the Telrad Dew Shield + with its 90 degree mirror allows for right angle sighting through the Telrad, and it doubles as a dew shield by pivoting over the top of the Telrad to slow the formation of dew forming on the reticle projection optics.

The Dew Shield + is an elegant solution that not only extends the time you can use a Telrad before dew takes over, it also protects the Telrad reticle, which can deteriorate from repeated formation of dew on its surface.

Friction holds the dew shield in either an open or closed position. The amount of friction can be adjusted by tightening the two screws that hold the dew shield to its metal attachment brackets. To use, flip the Dew Shield + back and lower its built-in flip mirror from its home position to a 45 degree angle, then look downwards to the top of the Telrad to see the relfection of the red illuminated reticle. To use as a dew shield move the flip mirror to home position, and flip the device forward.

LE Pyxis

I have received LE Pyxs, very good quality, but does not work with Linux.
But I'm in contact with Optec to get the Linux driver.
We'll see later if it works properly.

Excellent Integrated Package

I bought PRISM v.10 Pro for its integrated capabilities. I did not want to have to "bolt together" different software packages to achieve all my objectives. Two weeks after downloading the software the skies cleared and I was able to use my ZWO CMOS camera and focuser mounted onto a Stellarvue 80mm to move all over the sky finding and taking test shots of Messier objects. I am currently working on deepening my knowledge of what the software can do, particularly pointing models and autoguiding. The look of PRISM is a little outdated - others have mentioned this - but when you discover what you can accomplish with this software package this is easily forgotten. The online tutorials work well to get you off and running and phone support is quite good! I look forward to learning a little bit more each day and to achieving high quality imaging.

Looking forward to trying it!

I bought this in anticipation of using it at my summer home. So it is still unwrapped. It did come highly recommended, and the shipping speed was nothing short of miraculous, so I can't wait to get down to work!

Great device and excellent service.

This is my first experience with Hyperion. I had quick shipping and good service. The eagle is an excellent device for controlling my telescope and camera. It is a powerful pc.

Really does the job...

For those who have the Eagle, the ECCO is a great device to monitor and adjust the dew heater. It is very easy to install. You do a short calibration in the advanced settings, be sure the sensor is properly placed, plug in the cables and bingo--all done. Highly recommend it.
