Re: Reflection in image


Stone, Jack G
 

There were some articles written on the 12” when it was first released.

One of which was a baffle leak – I tried to google it but to no avail.  But it was reported both in the US and UK predominantly –

Also was the mirror support design – there were modifications as well, seems as though there were some distortions.

There were other mentions as well – If anyone has any references to these articles – would be appreciated.

you might try extending the baffle a few inches (or experiment) and see if you can eliminate it?

 

I had a similar issue on my cdk20. After I isolated the cause using paper baffle extensions, my solution was to 3d print a baffle extension and attach it 

 

Problem gone.

Robert,

I have been fighting the same thing on my 12"GSO RC for years.   I have a truss system.   If you find a remedy, please let me know.  Recently I placed protostar flock on the tube portion of the scope to make it even darker, but I doubt it will help.  It seems to happen when my scope is pointed between 10 degrees and 30 or so degrees, and is less frequent when I am pointed more towards the zenith.  I think it also happens when there is a bright star nearby.
