TS-Optics Photoline 90mm f/6.6 FPL53 Triplet Apo

Description

This is my new scope. It should be an ideal addition to my 8" RC, which is great for smaller objects but has a too small field of view for all the larger objects. The TS Apo has a focal length (with the Riccardi-Reducer attached) of 450 mm which is obvious great for wider fields. It was a long hard process of decision which scope to buy, but in the end the TS-Optics Photoline 90mm f/6.6 FPL53 Triplet Apo made it. Its aperture is big enough to capture some detail and its FL is small enough to be a widefield telescope. Everything can be screwed together, so i hope to avoid tilting. The focuser is rotatable which is very nice :-)

In image B) you can see the spacing between the Riccardi-Reducer and the the chip. APM and TS state that the distance should be 76.2 mm (which is shown by the green line). If i subtract the flange of 17.5 mm added by the camera, the distance should be 58.7 mm (indicated by the white line).

I cant wait for the first light, but in the moment clouds and rain are the only things visible in the sky :-( I need to check if all the distances are correct, but i totally need a star for that :-)

[Update 2019-10-10] The rotator is easy to use. Just loosen the screw and then you can rotate the whole OAZ in any direction.
