Shadows and reflections in Lodestar ,TS OAG

[Firas]

Hello, 

I sat up an OAG with lodestar and TS 16 mm OAG, connected to the imaging train that consist of,

Paracorr type 2, Moravian G2.  The scope is 8 Newtonian.  

There is great deal of reflections that it is making it difficult for Lodestar to see stars properly. Also a big black spot (1st image)

It does guide but with minimum capacity, which is, I think, effecting guding. 

Any idea how to fix this? 

Here is a couple of images of how it looked like last night. 

Thanks

@gorann Hi, Wim says that you have the same OAG setup. Any idea how to go about this? 

Thanks in advance

I will think about it. I also just started using the same OAG om my Esprit 150 (I have a ZWO OAG on the big Meade) and after rapidly looking through my subs from last night I may have a similar issue with the TS OAG, but not at all as bad. I have to look more into it tomorrow (right now waiting for the neighbours to arrive for dinner). I wonder if light could be leaking in from the side. Just a thought.

The big black thing might be the prism set too low into the imaging train

I think people do flats and adjust until you can't see it anymore
