Visibility IV / V
The evening looked clear, so I decided to try the new Optolong L-eNhance multi-narrowband filter. The California fog seemed to be an easy destination to start with due to its relatively easy discoverability. Even though there is only about an hour and a half of exposure here, of which about 5 minutes is RGB, I got surprisingly good detail. Actually, the efficiency of the whole filter surprised me. I got more detail in the middle of town on a bortle scale in maybe 7 or 8 and a half hours than I did before shooting this subject in RGB in three hours. Unfortunately, that RGB data last time suffered from a strong “walking noise” phenomenon, so I couldn’t use it for that. Otherwise, I would probably have added it to this when it was taken with the same optics.
