Tilter ASToptics M48/M48 0-10°

AStroptics M48/M48 0-10° Tilter

Stars look sharp at the centre of your image - but soft and elongated in the corners? This is a common problem in astrophotography. It usually means the camera sensor is not perfectly parallel to the focal plane of the telescope. The AStroptics M48/M48 Tilter solves this directly. It lets you fine-tune the tilt of your camera relative to the optical axis of the telescope, so the sensor sits exactly where it needs to be.

What does the tilter do?

The tilter fits between your telescope focuser and your camera. Once connected, you can adjust two things independently:

• The tilt angle - from 0 to 10 degrees
• The flange distance - from 0 to 3 mm

This combination gives you full control over the final position of the sensor. Small corrections make a big difference across the full image area.

Who needs a tilter?

A tilter is especially useful for photographers using full-frame sensors. The larger the sensor, the more visible any tilt becomes - particularly in the corners of the frame. If you have already collimated your telescope and are still seeing soft corners, a tilter is the logical next step.

Connection and compatibility

The AStroptics M48/M48 Tilter uses M48x0.75 female (internal) threads on both sides. This means it connects directly to any telescope focuser or camera adapter with a standard M48 male thread. No additional adapters are needed in most setups.

Build quality

The adapter is made entirely from metal. It is built for regular use in field conditions - meaning outdoors, at night, in changing temperatures. The construction is solid and the adjustment mechanism is precise.

Summary

The AStroptics M48/M48 Tilter with 0-10° adjustment range is a precise and practical solution for anyone who wants sharp stars across the entire image - not just at the centre. It is straightforward to set up and built to last.
