Description

APM Riccardi Adjusting flange for M82 reducer

A common problem for amateur astrophotographers: Focusing the optics as perfectly as possible and yet sharpness is still not completely achieved  at one edge/side.

Causes of this edge blurriness 

Possible explanations:

1) imbalance of the camera sensor (only fractions of a millimeter are sufficient)
2) Tilting of the focuser
3) Mis-collimation of the optics
4) Tilting of the eyepiece-side accessory (clamping or screwing)

the solution:

With APM’s M82 adjustment flange (basically a tilting mechanism) you can simply adjust the position of the camera’s chip to the field of the telescope, no matter where the cause of the tilting is (only with inaccurate collimation you should check the optics, since still other errors can appear). All you have to do is maintain the location and location of the adapter, correctors and camera, etc.

This is how it’s done:

1. Make a test shot and identify the location of the Blurred Region
2. Loosen the countersunk screws (grub screws)
3. Adjust the adjustment screws where you see the image deterioration
3. Make another test shot. In case of image deterioration, you have turned in the wrong direction, then simply adjust counter direction. Improving your image is the way to go.
4. In the meantime, repeatedly make test shots and optimize the settings until you have an image with optimum sharpness.
