Bob Eisenman Posted December 21, 2019 Share Posted December 21, 2019 (edited) Hyperstar converts your SCT(Schmidt Cassegrain) F10 telescope to an F2 telescope. This reduces deep sky imaging times from 30 minutes (at F10) to about 30 seconds (at F2). https://starizona.com/store/ And https://www.celestron.com/blogs/knowledgebase/what-are-fastar-and-hyperstar-how-do-they-work A Hyperstar compatible Celestron CPC HD 800 (uses GPS) https://www.celestron.com/products/cpc-deluxe-800-hd-computerized-telescope used on eBay in the $1500 price range: https://www.ebay.com/itm/Celestron-CPC-Deluxe-800-Edge-HD-8-Telescope/303307070879?hash=item469e829d9f:g:xOMAAOSwxcJdlSv4 To use the Hyperstar technology the Schmidt Cassegrain's telescope's secondary mirror is replaced with the hyperstar's lens assembly ($999): After adding Hyperstar and a high quality imager to the existing SCT the cost of the Hyperstar/ccd implementation runs about $1200+ depending on your choice of ccd imager.
