About this item

This Version utilizes the same construction as the 2" Everbrite Diagonal #DPC-2002, except for the shorter front. This new "short front" Diagonal was designed to allow more "through fork" motion when used with the new ACS-0004 Short tube Schmidt Cassegrain Adapter.
This Diagonal can also be used in any other 2" Diagonal application as well. However the Standard 2" Everbrite Diagonal (DPC-2002) provides increased locking stability in non SCT applications

Important notes for users of f/6.3 SCT Reducers
1) The ACS-0004 & DPS-2004 combination may also be used with f/6.3 SCT focal reducers, permitting larger fields of view with 2" eyepieces. However, the additional physical length of the f/6.3 reducer means the ACS-0004 & DPS-2004 combination will no longer pass through the fork arms of some SCT's

2) With the extra path length of the 2" Diagonal, the f/6.3 converter will actually produce an f/5.5 system. This combination works well with the Tele Vue 27mm Panoptic, yielding a 1.5 ° true field of view with a C-8. Note that longer focal length 2" eyepieces may vignette severely. Also, some eyepieces (such as 2" Naglers) may not reach focus with this combination due to their shorter path length.

3) When the 2" diagonal is used with 1¼" eyepieces, the Tele Vue 2" Converter Adapter (CEA-2125, Adorama SKU #TVA21QC) should be used to assure that focus is reached.
