Description

Halpha and Oiii composition captured at the beginning of June.

Poor transparency and weak signal outside the Tulip made this a difficult capture.

I used 3min exposures for Ha and 4min for the Oiii (poor guiding and a faulty AVX mount).

Gain 200 at -20.

Optolong 31mm 7nm Ha and 6.5 Oiii.
