Internal reflection from the Cheapy ERF/C5/PST

It suffers from internal reflection and it really washes out detail and reduce the contrast by much...

I've tilted it up slightly but as I can tell from the herschel wedge image, I know it's still well within the field of view. So, I guess that I'll have to tilt it further.

Maybe to build something like the mechanism of a Tmax... of course, to make it simpler so that the cost will be lower... Time to go to the drawing board again.


Just a random thought, maybe a small rubbish bin will do the trick... grin
