Description

This image has been taken with 2 filters alternatively. Unfortunately, I couldn't detail this is the acquisiion details:
180 x 300s with IDAS NBZ
100 x 300s with Optlong l-extreme
This was not a choice, the l-extreme generate ugly halos stars. I decided buy the IDAS NBZ to get around this weekness. The l-extreme give better results in term of signal than the NBZ.
At the and I decide to merge the 280 images pre processed into the same stack after realining them.
Considering the try and fails, the treament process was very time consuming, I'm probably very bad but it tooks me more than 24h to make this image without including the shooting.
