Guiding for Astrophotography

After purchasing the ZWO ASI2600MM which has an APSC size sensor I opted to upgrade my standard ZWO OAG to the OAG L version with the larger prism.
This is a much improved version of the Off Axis Guider by ZWO. Feels a lot more substantial and premium in the hand. The larger aperture means there is plenty of room for the larger prism and stem to be in the image train without interfering with the image being captured by the camera, whether that be an APSC or Full frame sized sensor.
Paired with my ASI 290mm mini as a guide camera this is providing a perfectly scaled image to guide with on my CT10 scope at 1200mm.

The meter is of a high quality and works really well. Not only is it great for helping to find perfect balance in stiff mounts but it is a fantastic aid to fine tuning your mount for the best guiding. It will assist you in adjusting your worm drive/gear mesh to the optimum setting and giving you great smooth tracking and excellent guiding numbers.
