Overcome the challenges of astrophotography with the M42 Spacer Ring Kit, expertly designed to help you achieve the optimal back-focus distance for your camera in relation to your telescope. This kit is essential for capturing the best astroimages, as an incorrect back-focus distance can lead to compromised performance at the corners of full-frame imaging sensors, resulting in elongated stars instead of precise pinpoints.For instance, when using a RASA 8 with a ZWO ASI 183 MC PRO camera, the required back-focus distance with the included M42 camera adapter is 25mm. However, the ZWO ASI 183 MC PRO camera consumes a back-focus of 17.5mm. To equalize this back-focus distance, a 7.5mm M42 spacer ring from our kit is required.The M42 Spacer Ring Kit includes three differently sized spacer rings, allowing you to achieve the correct back-focus distance with various popular Celestron optical tubes and T-thread camera adapters. Using the M42 Spacer Ring is straightforward.
Adjusts back-focus between your camera and telescope for the best astroimaging results.
Threads to your T-Ring and T-Adapter with standard male and female T-Threads.
Kit includes 3 spacer rings of different lengths (7.5mm, 12mm, 30mm).
CUSTOMIZE YOUR SETUP - Adapt to various telescope and camera configurations using the included spacer rings, allowing for flexible adjustments to achieve the ideal back focus distance..
ENHANCE ASTROPHOTOGRAPHY - Optimize your image train with these rings, correcting for focus errors and improving overall image clarity, bringing distant celestial objects into stunning detail..
