Deep Sky Observations with eVscope 2 December 2021/March 2022

Conditions | Observation Overview | List of Observed Sky Objects | References

Since the beginning of December 2021, I own an Unistellar eVscope 2 telescope for observing and taking photos of deep sky objects. On this page, I collect information about observations from December 5, 2021 to March 20, 2022 (after the repair by Unistellar), that is during a phase where my eVscope 2 was not in correct condition (primary mirror under tension). In this phase, I used the newly released app version 1.5.0. The photos that were taken during this phase are be presented elsewhere:




Sky Region and Objects

In December 2021 to February 2022, I observed mostly the following sky area (some observed objects are indicated):

Observation Time

The observations in this phase started in December 2021 and ended in March 2022. They typically took place shortly after dusk, when it was sufficiently dark for a successful star alignment. In December, this was already after 5:30 p.m. In March this was already about two hours later...

Observation Location

The first observation sessions took place in Erkerode near Braunschweig (Germany):

Some of the observations took place in Mühlhausen/Kraichgau (Germany):

Equipment Used

When observing with the eVscope 2, I only needed the eVscope 2 and my iPhones or iPad. Partly, I also observed with my original eVscope in parallel in order to perform some comparisons.

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. This is certainly one of the reasons why I found some of the deep sky objects that I wanted to observe only sometimes or not at all. For astro photography, however, light pollution is not as disturbing as for visual observations. The sky quality is a litttle bit better in Erkerode.

eVscope and eVscope 2; both iPhones, iPad


After some collimation attempts (Jupiter, Algenib, Aldebaran) on both telescopes, my aim was to compare both telescopes directly at identical DSO.

GN: M 42, M 78, NGC 2024 Order:
M 42, M 78, NGC 2024 (with clouds), abort...
Observed from 8:30 p.m. until about 9:30 p.m. (then suddenly clouds appeared), SQM 19.9

Supper break during the observation of M 78 (long EV time, poor look)..

eVscope 2, iPhone 7

This was mainly about test photos at different focus settings to see how stars in particular look at smaller and larger misfocus. This should help to see afterwards if old photos have an inaccurate focus. I only collimated a bit, so the photos are not optimally collimated. This should also help in judging photos afterwards, but probably does not help much...

Problem: Tracking error with M 42, EV rarely got beyond 30 seconds, duration time stopped (same problem as Mr. Deeg had with M 42).
