Deep Sky Observations with eVscope December 2021/January 2022

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

Since the end of January 2020, I own an Unistellar eVscope telescope for observing and taking photos of deep sky objects. On this page, I collect information about observations starting at the end of December 2021 and ending at the end of January 2022, which might be of interest to other beginners. In this phase, I used version 1.5 of the Unistellar app. The photos that were taken during this phase are presented elsewhere.

Observation Time

The observations in this phase started at the end of December 2021. They typically took place shortly after dusk, when it was sufficiently dark for a successful star alignment with the eVscope. In December and January, this was possible already after 5:30 p.m.

Observation Location

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

Equipment Used

When observing with the eVscope, I only needed the eVscope and my iPhone.

General Conditions

In general, the sky above Mühlhausen/Kraichgau is "light-polluted" 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.

Observed Objects Observed Objects, Details Remarks Further Remarks
Dec 20
PN: M 27 Order: collimation checked, M 27, collimation?, M 27 (up to 15 min, but elongated stars) Observed with new app version 1.5.0 from 6:10 p.m. until 7:10 p.m., SQM nearly 19

eVscope focused

Session goal: compare the eVscope with the eVscope 2

eVscope and eVscope 2; both iPhones, iPad

After some collimation attempts (Jupiter, Algenib, Aldebaran) on both telescopes, the aim was to compare both telescopes using identical DSO.
Mar 15       I sold my eVscope

Bold: First observation during this observation period; G = galaxy, OC = open star cluster, GC = globular star cluster, GN = galactic nebula, PN = planetary nebula, P = star pattern, DN = dark nebula, C = comet, SN = supernova

DSO Details
Name Constellation Type Remarks
B 33 Horsehead Nebula Orion DN Better to see when exposed longer
M 1 Crab Nebula Taurus GE Seen well
M 27 Dumbbell Nebula Vulpecula PN Nice, test object for the collimation
M 33 Triangulum Galaxy Triangulum G Very faint, details recognizable only when longer exposed
M 42 Orion Nebula Orion GE Too large, somewhat blurry, Trapezium washed out
M 43 De Mairan's Nebula Orion GE Part of M 42
M 45 Pleiades, Seven Sisters Taurus OC Too large for the eVscope's field of view
M 71   Sagitta GC According to Stoyan, an unusually loose globular star cluster.
M 74   Pisces G Nice spiral galaxy, but in the eVscope just a faint dot/glow...
M 77   Cetus G Spiral galaxy, a bit more to see than with M 74, but in the end just a soft dot in the eVscope
M 78   Orion GE Two stars like eyes; bright when longer exposed
NGC 1977 Running Man Nebula Orion GR Better to see when longer exposed
NGC 2024 Flame Nebula Orion GE Rather faint reddish nebula next to Alnitak; better to see, when longer exposed
Jupiter     P As attempt for collimation

G = galaxy, OC = open star cluster, GC = globular star cluster, GE = galactic emission nebula, GR = galactic reflection nebula, DN = dark nebula, C = comet, PN = planetary nebula, SP = star pattern, HII = HII region (emission nebula in other galaxies)
