Here is how the Telrad (with its orange dew shield) and my 9x50 RACI finderscope fit on the front of my XX14i 14 inch f/4.6 Newtonian:


David,
Is that the Astrosystems Telrad dew shield? Where did you get an *orange* one?!!

Clear skies,
-- Shane


Yup, it is indeed one from Astrosystems. I got it at the Nebraska Star Party many years ago when Astrosystems was there. I originally put it on my 10 inch Newtonian, and that orange color really got some looks. Clear skies to you.

The Double Lyra Mounting Bracket will support a Telrad quite nicely. It has the additional advantage of easily being used for different sighters, so you can change from the Telrad to a finder scope, or use the thing on different scope.

One of these days I will write a full review.

I think it's time for a Telrad update. A little less plastic would work for me.


Speaking for myself, I love the old clunky look and feel of the Telrad! :grin:

But, if less plastic works for you, here you go: :)

Careful, Carol! "Clunky" is in the eye of the beholder. :)

IIRC, the Telrad was originally designed for D cell batteries, thus the large battery compartment. Considering the life expectancy of the AA batteries I have in there now, I suspect that D cells would last for centuries. :roflmao:

I, for one, have loved my Telrads since I came back to astronomy in the late 1980s. The design and function are perfect for me and I hope they never change.

Long live the King!

You may also want to look at a flip mirror addition to the Telrad. Makes it even more useful at weird viewing angles. Is dew a concern where you live? If so the Telrad will dew up first. You'll need to look at adding some warming resistors or dew shields. All said, the telrad still works well.


Is that the Dew Shield plus?

By the way, you might want to purchase the Telrad pulser kit and install it, very nice upgrade. Available here. Good Luck!

Also...I take it the Pulser blinks the red target on and off?

Yes; here's mine with the Dew Shield plus.

:lol: Ahhh Ron, "clunky" is beloved with the Telrad! I wouldn't change a thing on it, have had the same one since I got my first scope! :grin:

I agree with your thoughts on battery life!

Telrad does need a makeover. The components inside are very radioshack.


Don't be deceived. The interior components may look flimsy and cheap, but Telrads are all but unkillable!

:ubetcha: Indeed they are! I'm still using the original one I purchased in 2005, from Telrad themselves. I for one, would be very disappointed to see our beloved Telrad undergo changes.

For those that don't know the history of the Telrad, this might be of interest; and also explain why it's still the same unchanged Telrad today.

Another suggestion on the Dob rolling around:
Buy an Orion Soft case to protect it! Also with Perhaps something large and heavy put up against it to keep it from rolling ;I.e. The Dob Base and I think You will be in good shape.

Thanks for that link. Here's another interesting link about the Telrad story.

Thanks for the history links, great reads.

I always figured the design remained unchanged because the inventor had to do a very large run to justify the injection molding costs, and units sold today were still from the original run ;)

Jon, thanks for the additional link. I think knowing the history of the Telrad lets others know why we absolutely love them exactly as they are now, with no changes! It's a "love" thing for the man that gave us the Telrad!

Amen, Carol.

I still have my original Telrad and the family has now grown to four. I think Steve can rest in peace knowing that his wonderful tool has been accepted by so many of us.

It's probably still one of the best bargains in our hobby!

Thanks again, Steve. :bow: :bow:
