PRODUCT DESCRIPTION
Wider Fields and Faster Exposures on Your AX103S
The AX103S has an 825mm focal length at f/8 — precise for detailed targets, but slower and narrower than ideal for large nebulae and wide star fields. This focal reducer brings that down to 578mm (f/5.6), giving you a wider field of view and noticeably shorter exposure times for the same brightness.
Note: for imaging only — not compatible with eyepieces for visual use. Compatible with the AX103S only.
Who This Is For
- AX103S owners wanting wider fields and faster deep-sky imaging
- Astrophotographers shooting large nebulae, Milky Way regions, or extended star fields
Key Features
- 0.7× reduction — focal length drops from 825mm (f/8) to 578mm (f/5.6)
- Engineered exclusively for the AX103S for correct back-focus and minimal aberrations
- Lightweight at ~140g — easy to balance in your imaging train
