Description

Designed for TV-102 and TV-102iis.

Flatteners clean-up focus away from the center of an image. The 0.8x Reducer/Flattener for 102 Scopes reduces telescope focal length to 80% while flattening the field for up to 35mm frame formats. Although optimized for TV102 scopes, it also works with any non-flat-field refractors (such as doublets or triplets) from 800-1000mm focal length.

Model RFL-4087 is a 0.8x Reducer/Flattener for TV-102 and TV-102iis scopes and any 800-1000mm focal length refractor for imaging with up to 35mm camera formats. For TV-102 (non-"iis") it requires the RAD-1074 Reducer Body Adapter for 2" focusers. This reducer/flattener requires Imaging System camera adapter such as  CWT-2070 (Canon Wide T-Adapter with Bayonet for 2.4" Focusers), STL-1071 (SBIG STL Camera Adapter), or TRG-1072 (Standard T-Ring Adapter) to connect to camera.

Customer Reviews (4.4 / 5 · 5 reviews)

Emma ★★★★★

I was worried about edge stars looking like seagulls in my images, but this reducer/flattener cleaned them right up. The 0.8x reduction gives me a nice wider field without losing too much focal length.

Natalie ★★★★★

Finally got my focus looking sharp all the way to the edges with this flattener—the corners used to be blurry before. The 0.8x reduction is just right for giving me a wider field without sacrificing too much detail.

Ruby R. ★★★★☆

I’ve been using this reducer on my 102 scope for a few nights now, and the edge-to-edge star sharpness is noticeably better than without it. The only reason I’m not giving five stars is that the threaded connection felt a bit snug the first time I attached it.
