Which Starlight Instruments focusers is this adapter for?
This adapter is designed for Starlight Instruments' 2.0" focusers, such as the popular FTF2015BCR Feather Touch focuser. It provides the necessary threading to mount these focusers onto compatible Meade SCTs.
Will this adapter fit my Meade 8" SCT?
No. This adapter is specifically for the Meade 10", 12", and 14" SCT models, which use a larger-diameter thread on their rear cell. Standard 8" SCTs use a smaller 2" thread and require a different adapter.
How does this Starlight adapter help with imaging on my Meade 12" SCT?
By allowing you to install a Feather Touch focuser, this adapter helps you eliminate the primary source of image shift from the stock mirror-focusing mechanism. This stability is critical for:
-
Autofocusing: Ensures your V-curves are accurate and repeatable.
-
Guiding: Prevents the guide star from shifting during focus adjustments.
-
High-Magnification Imaging: Keeps planets like Jupiter and Saturn perfectly centered on small sensor chips.
Do I still use the original focus knob on my Meade SCT after installing this adapter and a new focuser?
No. The recommended procedure is to use the original knob to find a rough focus position and then lock the primary mirror down (if your scope has mirror locks). All subsequent fine focusing should be done exclusively with the external Feather Touch focuser for maximum precision and to prevent image shift.
Is this adapter all I need to upgrade the focusing on my Meade 14" SCT?
No, this component is the adapter only. To complete the upgrade, you will also need to purchase a Starlight Instruments 2.0" Feather Touch focuser separately. This adapter creates the secure mechanical connection between the telescope and the new focuser.
What is the benefit of a threaded connection for this Meade SCT adapter?
A direct threaded connection provides a much more secure and rigid attachment compared to slip-fit or compression-style adapters. This is crucial for astrophotography, as it prevents any tilt or flex in the optical train that could lead to distorted stars, especially at the corners of the image sensor when using heavy cameras or accessories.
