Was my ad deleted??

Posted By Roy Troxel

About a month ago (10/25/12), I posted an ad for my 12.5" reflector. The ad is now no longer visible in the Telescopes/Reflectors category. Is this because the ads are posted for only 30 days?

Thanks for any advice,

Roy

Laser Collimators

Posted By Roy Troxel

I have an Obsession 12.5" reflector on order. I included their barlow-laser collimator in the order, without really knowing anything about it, except what I read in the book "astronomy Hacks."

Has anyone here had experience with that particular device? It is made by AstroSystems.

Thanks in advance...

Telrad displays double image

Posted By Roy Troxel

The problem is solved. smile

The unit containing the LED somehow slid forward to a position almost underneath the display glass. This caused the lens to produce the double image. When I slid the LED unit to a position near the middle of the Telrad interior, the image returned to normal.

Phew!
