M42 - 20.10.2015 at 05.45 Mäntyharju Observation number 44473

Visibility IV / V

Ari Ollikainen, Konut tählet, Jaala

At times, this use starts to work for the forces, but it’s still worth it. Since Saturday, I’ve been poking at the cottage on a bright morning to take a picture of Orion with a CCD camera, and this morning then I finally snorted. Clear skies and frost. The 80ED tube would have required the installation of a reducer, but as the eastern sky began to lighten threateningly, I decided to bow to a tighter trim without Running Mania.

Aika hyvin tarttunut noin lyhyillä valotuksilla.

Yllätyin itsekin kameran herkkyydestä ja toisaalta tuo 80ED on melko nopea putki. Halusin myös välttää tuon trapetsin puhkipalamisen ja jätin siksi valot vähän vajaiksi.
