Vaonis Vespera - Further Observations with the CLS Filter

On this page, I describe further experiences with my electronic 2" refractor telescope Vaonis Vespera 50 mm/200 mm (f/4) when observing with the CLS Filter (light pollution filter).

Note: In June 2024, I sold my Vaonis Vespera smart telescope. I therefore cannot report any further experiences with it here.

Introduction

On this page, I compare some nebula photos that were taken without and with the CLS Filter and with both Filters.

First Conclusions

CLS Filter

Overall, the images with the Dual Band Filter are convincing for all objects, except that the colors have become somewhat unnatural due to the filter. In addition, the stars are more strongly suppressed, which makes the nebulae stand out more clearly and look more detailed. What you like better, however, may be a different matter...

After all, the Dual Band Filter does not seem to take away much light.

After all, the Dual Band Filter does not seem to take away much light; sometimes the photos even appear brighter at comparable exposure times.
