TS-OPTICS M48 TILTER

The TS-Optics M48 Tilter solves one of the most common problems encountered in astrophotography, where after accurate focusing, in one or two corners the stars are not pinpoints. Often, the sharpness of the image is compromise to a level that the image has to be cropped.

Some possible causes of this problem are:

• a tilted camera sensor (fraction of a millimetre are enough)
• a tilted focuser
• a tilted focal plane of the telescope (common in Newtonian telescopes)
• tilted optical accessories by imprecise clamping

As solution, a tilter can re-establish the parallelism between elements and therefore the details on the corners of your photo will return sharp.

The best way is to calibrate it is using test images:

1. Identify the corner of your photo which has unsharp / aberrated stars.
2. Loosen the 3 pull screws (the larger one).
3. Slightly turn the push screws in correspondence of for the corner of the photo that is unsharp.
4. Take a second image. If the sharpness has deteriorated, turn the adjustment screw in the other direction until all 4 corners of your photos has the same sharpness.
5. Tighten the pull screws.

This tilter is supplied with an M48 inversion ring male to male with an optical thickness of 2mm.
