There are some discussions as to whether a Telrad or a [red dot finder-> red dot finder] should be used as a finder for a [telescope-> telescope]. Anyone who opts for a Telrad finder has several advantages, but they come at a price, because the red dot finders are usually much cheaper.
Chapter in this post:
Advantages of the Telrad viewfinder
Here are the most important advantages that the Telrad system offers:
- Projection of concentric circles (while red dot finders produce only one point)
- The circles of a Telrad are provided in the Deep Sky Travel Atlas as an orientation aid, so that objects can be easily found with a Telrad and Deep Sky Travel Atlas
- the luminosity of the Telrad can be continuously adjusted from zero to maximum
- the three concentric circles correspond to 0,5 - 2 and 4 ° in diameter, so that you can get a feel for the angular distance
If you want to buy a Telrad, you can find it on Amazon, for example. However, you should also order a dew cap, because on cold winter nights the windshield thaws and you can no longer see anything. Both products are listed again here:
