Askar 0.7x Full-Frame 2.5" Reducer f/3.9 for Askar FRA400 72mm & FRA500 90mm Telescopes

Askar provides a brand-new F3.9 full frame reducer for FRA400 astrograph, further reducing the focal length and thus shortening the exposure time on its original 400 focal length and f/5.6 focal ratio design basis. The reduction factor is 0.7×, and the reduced focal length is 280mm, which can satisfy most deep-sky astrophotography. The back focus is standard 55mm. The reducer has built-in M48×0.75 thread, easy for the attachment of 2" filters.

Note: This item may or may not have the 'Askar' brand imprinted on the item as pictured above. It just varies from batch to batch.

ZWO Seestar S50 (ฟรี! ฟิลเตอร์กรองแสงอาทิตย์)

This is a fantastic product for EAA. With the variable weather here in Thailand, I am still able to get out under the stars for even a few minutes and get some great pictures, particularly of nebula and galaxies. I highly recommend the Seestar S50 for beginners and advanced astronomers (or wannabees).
