Hi,
This is the first time I've used an light pollution filter with my imaging . This is mainly for moonlight imaging and it seems to work quite well.
IC 4628 is a good challenge for an ED80 under moonlight.
I thought it may a problem processing out the green /blue background., and after several attempts in photoshop I stumbled across an easy fix.
Before I did any levels or curves I hit the auto colour button and it balanced quite well.
I ran out of time to do a direct comparison without the filter, the fog rolled in. I intend to do so when the monn phase is the same.
Equipment.
ED 80, orion field flattener, astronomic cls light pollution filter.
HEQ pro 5 mount. Orion mini guider.
Unmodded canon 1100D,
11 x 8 minute subs, ISO 800, darks and flat frames applied.
Median stack in DSS, processed in PS7.
Cheers,
Justin.
