Variable projection adapter - for 2" connection
The projection and focal adapter is a high-quality solution for all telescopes with a 2" connection. It also accepts large diameter 1.25" eyepieces, such as Super Plössls with a 32mm focal length or wide angle eyepieces. These eyepieces are often too thick for other projection adapters. But the individual parts that make up the adapter also make a lot of sense, see the description:
The advantages at a glance:
Many 1.25" eyepieces can be used, especially those with a slightly larger diameter.
The T2 fitting can be moved, this allows the projection distance to be changed and therefore a "zoom effect".
Eyepieces are held in place by a ring clamp with 2 screws, preventing tilting
The components can also be used individually and make a lot of sense.
Possible adaptations through the individual parts:
2" to 1.25" adapter with attached T-2 thread and compression ring - universal eyepiece attachment
T-2 to 2" adapter with robust compression ring - allows adaptation of 2" accessories to T2
2" to T-2 adapter to adapt T2 accessories to 2" focusers - the 2" focal adapter
Our expert comment:
What eyepieces fit on this adapter?
A classic 1.25" projection adapter only accepts very narrow eyepieces of the Kellner and Plössl design. However, most modern eyepieces have a much larger outer diameter. What to do? The 33220 projection adapter is suitable for this.Your eyepiece can have a maximum outer diameter of 47mm diameter and a maximum length of 46mm (without cap).If the eyepiece is thinner at the top (up to a maximum of 37mm cone diameter), can be 61mm long, see also sketch.
