Vaonis Vespera Pro - Observations with the Dual Band Filter

Introduction | Photos with and without Dual Band Filter | First Conclusions | Links

In progress

On this page, I describe first experiences with my electronic 2" refractor telescope Vaonis Vespera Pro 50 mm/250 mm (f/5) when observing with the Dual Band Filter. The page is still under construction, as I have only observed a few objects with the Dual Band Filter.

Introduction

On this page, I compare some nebula photos that were taken without and with the Dual Band Filter with the Vaonis Vespera Pro.

First Conclusions

Overall, the images with the Dual Band Filter are convincing for all objects observed so far, 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 too much light; sometimes the photos even appear brighter at comparable exposure times. For some objects, however, very long exposure times seem to be necessary with the filter, as I have learned in the meantime...
