Astrophotography Fit
Best for general deep-sky imaging and visual observing when the mount, camera format, and correction hardware are chosen as one system.
ZWO FF107 APO sits in the telescope slot for general deep-sky imaging and visual observing. The useful headline specs are aperture 107 mm, focal length 749 mm, f/7.
Camera coverage: Full frame / APS-C / Micro 4/3. Image circle: 44 mm. Back focus: No strict flattener spacing required within focuser travel.
Refractors keep the field routine calmer: no regular collimation, predictable cooldown, and a clean path to autofocus and filtered imaging. The tradeoff is aperture and reach.
Weight matters here: 5.7 kg / 12.6 lb. Leave payload headroom for the camera, guider, focuser, dew control, and cables instead of judging the mount by bare tube weight alone.
Best paired with
- Corrected field flattener or reducer when the design requires one
- Cooled APS-C or smaller astro cameras matched to the image circle
- Autofocus, guide scope or OAG, and a mount with comfortable payload margin
Not recommended for
- Large full-frame sensors unless the corrected field supports them
- Very small travel mounts near their realistic imaging payload limit
- Buyers expecting one telescope to be ideal for every target size
