More product information
The Telrad is the best-selling non-magnifying finder for Dobsonians, equatorial reflectors, refractors, and Schmidt-Cassegrains alike.

The Telrad projects a bull's-eye pattern of concentric red rings (4 degrees, 2 degrees, and one-half degree in diameter) on a tilted clear viewing plate at the top of the finder. These circles, which seem to be projected on the sky itself, make it easy to starhop from object to object. If a galaxy is 10 degrees north of a known star, for example, two 4 degree Telrad jumps and one 2 degree jump from the known star will take you to that galaxy in seconds. The half-degree circle makes it easy to quickly center a computerized scope on guide stars for start-up alignment, and to center on planets, comets, and deep space objects if you’re scanning the sky manually. The red circles can be seen from virtually any distance behind the Telrad, from two inches to two feet, so eyeglass-wearers can easily use the finder.

The Telrad is normally used as a straight-through finder, similar to the heads-up display in a military aircraft cockpit. Its base attaches quickly to any optical tube 6” and larger in diameter by means of double-faced tape (or by screws into a Sonotube reflector optical tube, through two screw holes in the mounting plate). The finder itself fits into a dovetail slot in the base and locks in place with two finger-tighten side screws. The Telrad comes with one base standard, but additional bases are available so you can put a base on each scope you own and use one Telrad on several scopes.

An optional Dew Shield retards the formation of dew on the optics of the Telrad during long observing sessions. Additionally, an optional Dew Shield Plus combines a dew shield with a pivoting light-weight first surface flip mirror that allows the Telrad to be used as a straight-through finder, a right angle finder for observing at the zenith, and at any angle in between.

Collimating knobs at the back of the Telrad allow you to line up the finder with your main scope optics. An on/off switch and integral rotary brightness control allow you to match the finder brightness to your eye’s dark adaptation. An optional Pulsar pulsing reticle module is available to provide variable brightness and a variable on/off light cycle that many observers find more comfortable to use when hunting very faint objects. The Telrad uses two 1.5V AA batteries (supplied by Astronomics as part of our Telrad package).

The Telrad is 8” long by 1.75” wide by a maximum height of 5”, so it is difficult to use on the short and small diameter optical tubes of small scopes such as the Meade 3.5” ETX-90. If a non-magnifying finder is needed for such scopes, consider the #3960 Rigel Quikfinder instead.

Hard to go wrong with a Telrad. I'm a big fan of non-magnifying finders, but the dimmable circles sealed the deal for me. I have a hard-copy star atlas that comes with "standard" Telrad-sized circular overlays for showing parts of the sky that would be in your Telrad's field of view when star-hopping, and it's been very easy and intuitive to use.

For years I made do with the little finder that came with my scope, having no idea what I was missing until I used a friend's scope that was equipped with a Telrad. What a difference! I went home and ordered one that night. The 1x power of the Telrad means I no longer get confused by the dozens of stars my old finder showed me in an area where my naked eye only saw two or three. I don't think I have uncapped my old finder since I got the Telrad.

The only real downside that I must mention is that it is BIG! Definitely overpowers a smaller scope.

One of the best things I ever bought was a Telrad. Makes finding objects so much easier. I have been surprised how well the device does with batteries as well, I have accidentally left it on over night on a couple of occasions and it still had life.

The AA cells in my 4 year old Telrad corroded and somehow managed to ruin the electronics. Maybe it was the corrosive gasses? A new battery holder wired into place made no difference. I replaced it with a Rigel Quickfinder 10 years ago and am still using the original button cell without issues. The Rigel is missing the largest outer ring, but it does have a built in pulsing feature missing on the Telrad. It is also much smaller and lighter. I'd rate it a 5 for ease of use, but since it doesn't work at all now, I'd rate it a 1 since it is useless, thus the compromise 3 rating because of poor durability and bulkiness. Maybe the manufacturer should consider switching to lithium button cells like the Rigel and shrink the size correspondingly?

The Telrad is an indispensable replacement for the finder scopes that come with your telescope. Once it's aligned with your telescope, precisely slewing to any visible star simplicity itself. And it makes the initial alignment of your Goto a breeze.
