Grab myself a Telrad yesterday at Bintel. What a useful device it is! Save many frustration attempts finding objects in the sky and my sore back from looking into the viewfinder all the time. If you have a goto mount, this helps finding alignment stars with ease. Also, much easier to predict when the clouds are coming in on the object you are looking at.
There are 3 red circular HUD with adjustable brightness so you can blend the HUD to the foreground stars. 3 adjustable collimating screw for pinpoint accuracy.
If you haven't got one yet, I highly recommend this magic device.
The Telrad is surely one of the best options you can put on your scope. I don't use a finder scope but rather, a combination of Telrad and low power eyepiece.
each to thier own... i prefer a right angle finder as i dont have to bend my neck at all but thats me.
with so many ppl with telrads (or other zero mag finders) they must be good for the majority of ppl
Vingo, only someone who does not own a Telrad could talk like that. The combination of right-angle finder + 1x finder like the Telrad is ideal. They are complimentary tools.
The Rigel quickfinder is a good alternative to the Telrad for smaller scopes (8" or less), as it is much smaller and easier to mount next to your 50mm finder and at a comfortable distance from the focuser.
One issue I did have with mine though - The plastic target that the light shines though actually fell off mine the other day. It was a simple job to glue it back on, but I would have hated for that to happen outside.
While I am well and truly a Telrad fan (I've got two...) they can and do get quite "dewy" if you do not take appropriate precautions...dew shield, dew heater etc. any and all solutions can be bought or made DIY style...

I agree that Dew can be a problem. I would like to hear more about those solutions though. How does the shield fit exactly?

The shields are 'OK' for mild dew, but they can't compete with a dew heater.
Lauries mods (Dew heater and variable pulse for the targetting rings) make using the Telrad a dream.

Let me first disqualify myself...I am by no means an expert but here are some of the "solutions" that I ahve seen or tried...
Dew Shields...work reasonably well in light to moderate dew...
Possible solutions...dew shieldsHomemade...I've seen something as simple as a towel used, a foam or cardboard folded (u-shaped) folded over like a small roof, and my personal favorite an old foam stubby holder (where I started and worked well).Store bought...Telrad dewshield and dewshield plus...work pretty well and "fit" right on the Telrad...the dewshiled plus has a mirror to turn it into a right angle finder too...I've not had a lot of success and enjoyment from the dewshield plus. I've got a dewshield and a dewshield plus...I'd skip the plus...both work for dew (light to moderate)...I have not seen a big difference in performance between the storebought and the home made...
Possible solutions...dew heatersHomemade...see Raj...for this and other mods...I hear it works real well...Store bought...Kendricks has a commercial one available...it is a tiny "electric pad: that is held by a rubber band to the side of your Telrad...it works but is inelegant. Telescope Solutions has a neater looking rig (Moonlight used to make/sell them) that looks like a "U shaped" heater element...never used one. I am sure that other companies have them as well...the plug into a "controller unit" to power them...
I've got a Kendrick...again, it is functional but not pretty...
Vingo, only someone who does not own a Telrad could talk like that.
the one or two times i have used on of these i found i still had to crane my neck around to see thru it... maybe some sort of mirror right angle system.....
Hi Eric. It runs off 12 volts which plugs into the socket, (with small red LED), at the right. The switches control the heater & whether in constant or flash mode. The pot on the other side controls the flash rate, which is variable from ~1 sec on/1 sec off, to 1 sec on/4 sec off. I do not touch the original on/off dimmer switch.
HTH. L.
