Description

The seeing was so bad that I decided to use the best single frame from around 500.
Autostakkert tried its best but I preferred the single frame.

Double stacked Lunt40 etalons on the rear of a SW150 f/8.
The Televue PowerMate 2x goes in front of the Baader TZ4S so it "sees" an f/16 scope.

Rear placed air-spaced etalons work better at longer f numbers.

I owe Christian Viladrich a lifetimes supply of beer & gratitude for his studies into these things.
