Description

This is my early try of Rosette this season. I collected date during two nights. Started in Abastumani on October 19th, but could only capture H-alpha channel as the sun rose. I left Abastumani the next day but wanted to complete this project, so I drove outside Tbilisi again last night to collect the remaining channels. Here is it, the result of 2h32min total exposure!
