Description

Consecutive clear sky in Hong Kong spring is definitely a rarity. This is by no means anything spectacular. I could add Ha data to it later, but I'm afraid it might throw off the overall colour balance a little bit. We shall see. 

It is quite impossible to elicit IFN from a light polluted city, but I'm really quite pleased with the overall result.

The L channel is acquired using the Epsilon 1.5x extender (650mm F/5)43 frames x 2min
The colour data is acquired using the default corrector (430m F/3.3), 30 frames x 2 min
