Adattatore variabile 2"

Codice articolo: TSVPA2

Variable eyepiece projection adaptor for large 1.25" eyepieces
2" telescope adaptation

The Deluxe Projection Adaptor is a particularly high quality solution for all telescopes with 2" focuser.

It accepts most eyepieces with 1.25" barrel, including medium sized eyepieces that would not fit into a regular projection adaptor (maximum overall eyepiece diameter: 45 mm). Examples of this would be 32mm Super Plossls or 1.25" WA eyepieces.

The VPA2 is a modular adaptor. Each of its individual parts can be very valuable on its own! (See below)

Advantages of the TS VPA 2:
-- You can use almost all 1.25" eyepieces, in particular those with a slightly larger body than normal.
-- The T2 adaptation can be extended for fine-tuning of the projection distance. A larger distance translates into a stronger
zoom factor.
-- The eyepiece can be locked with two locking screws that tighten a compression ring.
-- The individual components of this adaptor have a lot of additional applications.

The TS VPA 2 consists of the following components:

The individual components that make up the TSVPA2 ... from left to right:

Adaptor from 2" to 1.25" with integrated T2 thread and compression ring

Adaptor from T2 to 2" with compression ring. Allows you to attach 2" accessories to adaptors with T2 thread

Adaptor from 2" to T2 - prime focus adaptor for adaptation of T2 accessories to 2" focusers

Assembling the VPA adaptor:

Step 1:
Screw the T2-2" adaptor onto the 2"-1.25" adaptor with integrated T2 thread.

Step 2:
Insert the projection eyepiece and clamp it. If the eyepiece has a rubber eyeguard we recommend removing this eyeguard.

Step 3:
Insert the 2"-T2 adaptor on top of the eyepiece and clamp it with the locking screw of the central part.

Hands-on advice from Teleskop-Service:

Classical Projection Photography with cameras without objective lens:
With any given projection eyepiece the zoom factor is increased with growing distance between the eyepiece and the camera's sensor. We recommend to avoid extremes: A too short distance might cause vignetting towards the edge, a too big distance will render a too high magnification. We recommend projection eyepieces between 9mm and 15mm focal length.

A-focal imaging with compact digital cameras with objective:
For this kind of photography the camera's lens needs to be moved as closely as possible to the exit lens of the eyepiece. The eyepiece needs to have as large as possible lens diameter. Both factors combined will optimize the field illumination.

Tip for the eyepiece adaptation:
If your eyepiece has a rubber eyeguard we recommend to remove this eyeguard. Often this allows to move the T2 thread closer to the eyepiece.
