Description

Site : Gunwigoon, KOREA

Telescope : GSO RC10" + CCDT67

Mount : Rainbowastro RST400

Camera : QSI690wsg, Lodestarx2

Exposeure : Ha 12 x 600s, L 24 x 300s, RGB 12 x 300s each (Total 7h 00m, All 2x2 Bin)

I have tried 2x2 bin imaging because of the oversampling isseue.

The seeing of my observatory is very poor so the quality of the image is almost same before.

But I'm sorry for the low resolution.
