Deep Sky Observations with Vespera Pro from March 27, 2025 on

in progress

Since the beginning of May 2024, I own a Vaonis Vespera Pro telescope for observing and taking photos of deep sky objects. On this page, I collect information about observations beginning with March 27, 2025. The photos that were taken during this phase are presented elsewhere (on the detail pages for the DSO).

 

Conditions

Sky Region and Objects

From March 27, 2025 on, I observed mostly the following sky area (some observed objects are indicated):

Observation Time

The observations in this phase took place beginning with March 27, 2025. They typically took place shortly after dusk, when it was sufficiently dark for a successful initialization of the Vespera Pro. At the end of March, this was typically after 9 p.m (MESZ)..

Observation Location

The observations took place in Mühlhausen/Kraichgau (Germany):

Equipment Used

When observing with the Vespera Pro, I only needed the Vespera Pro and my iPhone or iPad. I used the Gitzo Systematic High Tripod that I had acquired for my Vespera (Pro). Moreover, I purchased filters for the Vespera (Pro) that I did not use during these observations.

General Conditions

In general, the sky above Mühlhausen/Kraichgau is "light-polluted" (SQM 20.5) and does not invite you to search for deep sky objects. For astro photography, however, light pollution is not as disturbing as for visual observations.
