Quote:My Telrad changed my life! It cleared up my acne, helped me to lose 50 pounds, got me dates with the hottest girls, caused my truck to get an extra 5 miles per gallon, and its mere presence in my house raised the value of my home by $10,000.

Quote:Quote:Man, you'll really cringe when you learn that there's a Telrad on the 48" UK Schmidt at Siding Spring Observatory, and on the 60" at Mount Wilson, shown below. I have seen Telrads on other observatory scopes, and they are only installed for the case when the pointing is not established or working correctly.Tom Great pic. I was surprised to see that the 24" Clark refractor at Lowell Observatory also has a Telrad. I'm sure Percival Lowell found it handy for tracking down Mars.

Quote:Quote:Hey Steve, where did you get the cool little triangular map tool? I bought it at my local astronomy shop back in the early 1990s. I have not seen any others since. It's designed to mimic the Telrad pattern, and be sized for use with Sky Atlas 2000.Wish I could point you in the direction to purchase one, but I'm not sure they are made any more.I'm sure it would be easy enough to make one from a bit of plastic or glass.Steve
Send me your Telrad! I kinda like them and if you have any issues, they would be mitigated by ridding yourself of those pesky things. . . and you would enjoy listening to the lamentations of all those folks who disagree with you!!
And if you really missed the Telrad - I would immediately return it to you!
Needing one for my newly acquired DOB - your friend,
Quote:Since the Telrad is such an inexpensive gizmo, I'm kind of surprised that it's developed such a loyal fan base. Think about it. The Telrad doesn't cost multiple hundreds of dollars, it has no green letters, there is no long waiting list to buy one, I doubt if it's ever backordered, it's not made in Japan or Germany ... what's up with that?

Quote:I recommend both a Telrad and an optical finder. They complement each other very well. I prefer the Telrad over any other red dot finder.
Quote:The DOB is a 2006 model Zumell 10" f/4.92 - given to me for trial - if I like it, my friend will get a couple of hundred $$. Honesty, I can't see not buying this scope! It's very nice!! There's a Telrad mount already attached. So far it seems like a really nice scope. . . of course since I received it - the sky has been nothing but clouds and snow!!! So the curse extends to trials as well as purchases ! ! ! Go figure.

Quote:For me, star hopping with just a Telrad would be too much of a bother. Do I really want to map out how many Telrad circles of 4 or 2 degrees I would need to reach a certain object? No, not really. That's too much like work for my taste. The less plotting of degrees, star hops and Telrad circles the better. Instead, I sight on the nearest visible star with the Telrad, then use Sky Safari and the optical finder to star hop to the object. Easy sneezy. I can do this on-the-fly with no preplanning. As a bonus, I get to see the route and destination with a nice rich-field telescope, my 15x70 finder. You don't get that if you just use a Telrad.Mike

Quote:That is not really how it works, any such mapping is generally unnecessary and if is necessary, Sky Safari shows separations.
Quote: Using the Telrad is all about matching patterns and positioning the Telrad circles relative to stars that are visible naked eye. It's very effective if the skies are reasonably dark and it's a whole lot simpler than using a magnifying finder because it can be done with stars that are visible naked eye.
Quote:If you don't want to use it, don't. But let others who do know how to use the Telrad effectively discuss it's use.

Quote:That backwards mounted Telrad would make star-hopping challenging, wouldn't it?

Quote: That's how I can avoid plunking in a "finder eyepiece" and go straight to a moderate to high power eyepiece in the focuser.
Quote:Mike,I use both a Telrad and a RACI finder for star-hopping. The Telrad is faster to get me to the 'hood, then the RACI takes over.Cheers,Ron
