From Astro-Physics:
Astro-Physics introduced the redesigned Stowaway at the Northeast Astro-Imaging Conference on April 18, 2018. Long-time astronomers will recall that we offered f5 and f7 Stowaway refractors from 1999-2002 that are cherished today for their portability and performance. Indeed, our own Stowaway has traveled with us to star-gaze in far off places as well as to watch whales, boats, birds and other wildlife. While observing the solar eclipse in August 2017 from Wyoming, we had so much fun with our original 92 mm Stowaways that we decided to make two additional production runs, which were shipped in 2018-2019. The response and feedback has been so positive that that we are in production with a third run run of this scope for 2020 delivery.
This triplet lens scope has the same extraordinary quality that you have come to expect from Astro-Physics with a few new exciting features:
- Grab ‘n go visual travel companion. Follow eclipses around the globe or observe wildlife from afar!
- Dramatic deep-sky imaging with its optional Field Flattener (92FF) and Telecompressor Corrector (92TCC).
- Silky, smooth 2.5” Starlight Instruments Feather Touch focuser with dual-speed mechanism. The dual-speed feature is particularly advantageous for critically focusing this fast focal ratio. A digital focusing system is available for imaging.
- Rotating focuser enables you to frame your photos for optimal, artistic composition.
- Compact, lightweight tube assembly travels easily in its Pelican Air case.
- Fully retractable, felt-lined dew shield slides to its fully-extended position and then secures in place.
- Latest multi-coating technology will provide optimum light transmission.
