Description

A refractor WF image of the NGC6781 nebula and an image stack that consist of 81x60sec subs.

I have used 4 pcs of 2" filters, a UV/IR block filter, IDAS LPS V4, Optolong L-eNHance and a Optolong L-Pro filter. App. 20 subs used, each filter.

Why?

Just to test the filter performace in a Bortle 6 area. Conclusion is pending.

My home build observatory is placed in my front yard/in the "red light" pollution zone, have a look here,

Red Zone

Kind regards

Niels
