On Saturday I presented (slides here) our mirror-making and Bath-interferometry project at the annual meeting of the telescope&equipment division of URSA (the finnish amateur astronomy association). The program included talks by Petri Kehusmaa on supernova-hunting and J-P Metsävainio on image-processing and creating 3D stereo images.
The event was held at Tähtikallio obsevatory in Artjärvi, a 90 minutes drive northeast from Helsinki. The site features three permanent domes, two of which have big telescopes installed in them. The smaller one is a 16-inch (406 mm) F/10 Meade LX200 (Schmidt-Cassegrain), and the big one is an Astrofox 36-inch (914 mm) folded Newtonian. Between the clouds and a lot of drift-alignment I managed to catch some nice views of Saturn and M13 through both of these scopes.
