APM-Riccardi Universal Apo Flattner 1.0x - Model 1 for Apo Telescopes
Our new, universal flattener for Apo's was calculated from the famous optical designer Massimo Riccardi.
flattener "smoothes" the optical problems in the image circle caused by
coma and astigmatism, leading to a similar perfect image quality
as on the optical axis itself.
The flattener Model 2 is particularly designed for shorter focal lengths, and faster focal ratios. It currently represents the limit of what is possible.
There is no comparable flattener with such a good apochromatic longitudinal and lateral aberration correction on the market.
Other cheaper models fall short significantly , which is already obvious by their significantly higher vignetting but mainly by the drastically higher inferior lateral chromatic aberration.
The new flattener allows a generous working distance from the thread to the focus of more than 90 mm, see attached file, so that all common accessories such as filter wheels will find space.
Model 1 is suitable for the following Telescopes and telescopes with similar f-ratio:
- APM LZOS Apo 105 F/6,2
- APM Apo 107 F/6,5
- APM LZOS Apo 115 F/7
- APM LZOS Apo 123 F/6
- APM LZOS Apo 130 F/6
- APM-Riccardi Apo Doublet 140 F/7
- Backfocus from Thread Bodyend to Focus: see attached data sheet
- little focus change caused by reducer
