Deep Sky Observations with eVscope 2 August to December 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 August to December 2022 (third sample). In this phase, I used app version 2.0 and newer. The photos that were taken during this phase are be presented elsewhere (and on the detail pages for the DSO).

Notes:

See page Overview of the eVscope Pages for just that!

Sky Region and Objects

Between August and December 2022, I observed mostly the following sky area :

Observation Time

The observations in this phase took place in August, in October, and in December 2022. They typically took place shortly after dusk, when it was sufficiently dark for a successful star alignment. In August 2022, this was typically after 10:30 p.m. (summer time), in October already after 7:30 p.m and at the beginning of November after 6:00 p.m..

Observation Location

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

Coordinates: 49° 15′ N , 8° 43′ E
Coordinates (dec.): 49,25° N, 8,72° E

Equipment Used

When observing with the eVscope 2, I only needed the eVscope 2 and my iPhones or iPad.

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.

Observation Dates

Date 2022	Observed Objects	Observed Objects, Details	Remarks	Further Remarks
Aug 22 MH	GC: M 13 OC: M 11 GN: M 16, M 17 PN: M 27 G: M 51, M 101	Order: M 13, (M 27), M 13 (nennt er M 27), (M 27), M 51, M 101, (M 27), (M 57), M 17, M 11, M 16, M 27 I think 5 attempts at M 27; close on the 4th, but fumbled when changing the section (too fast), found it in the 5th attempt...	eVscope 2 (first light for third sample), iPhone 7 Observed after 9:30 p.m. up to about midnight; SQM 19.4...20.1	More often (2x?) EV2 named the new object after the old one, moved to the new object correctly, but named it wrong in the overlay... No darkframe, no collimation check, only sharpness set on stars and checked with Bahtinov mask. Especially on the left edge still triangular stars, but I leave it like this now!
Oct 22 MH	G: M 31/32 GN: IC 5070, IC 5146 PN: M 27	Order: M 27, IC 5070 (Pelican Nebula), IC 5146 (Cocoon Nebula), M 31 (Vespera und eVscope 2) In part, I exposed up to 30 minutes, in part a little more than 20 minutes; I also took photos in between (manually and with the Vespera also automatically); this observation was meant as a comparison of eVscope 2 and Vespera at long exposure times.	Vespera; iPad (eVscope 2, iPhone 7)	Observed from after 7:00 p.m. until about 9:30 p.m.; SQM 17...18 at the very beginning, 19 at about 7:30, 19.4 at 7:35, 19.6 at 8:15, later only 19.4; dew!!! Soon clouds were appearing... eVscope 2: No dark frame, no checking of collimation and focus
Nov 2 MH	OC: M 52, M 103 GC: M 15 G: M 31/32, M 33, NGC 7331 GN: IC 1396, IC 5070, NGC 281, NGC 6888, NGC 7635	Order: M 31 (labelled as M 33), NGC 281 (Pacman Nebula; 10 min), IC 5070 (labelled as Pacman; 10 min), M 15 (poorly centered; 5 min), IC 1396 (Elephant's Trunk, 11 min), NGC 7331, (NGC 7293), M 33 (still labelled as NGC 7331; 10 min), M 52 (still labelled as NGC 7331; 7 min), NGC 7635 (Bubble Nebula, 13 min), M 103 (6 min), NGC 6888 (Crescent Nebula; 17 min) This session was in part meant to replicate an observation session the day before that was done with the Vaonis Vespera, but became only a partial replication.	eVscope 2, iPad	Observed between 6 an 9:45 p.m. SQM 17...18 at the beginnng, 19 at 6:45 p.m., later lower again because of the moon... Sky "fuzzy", moon with "haze"... App: Often, but not always the wrong (previous) object name is displayed... Often the icons next to the camera icon disappear (which is then mostly inactive, but not always...).
Nov 24 MH	OC: NGC 457, NGC 663, NGC 869, NGC 884 GC: M 2, M 15, M 30 G: M 31 GN: IC 1396, IC 1805, IC 1848, IC 5070, NGC6960, NGC 6992, NGC 7000, NGC 7023 PN: M 27, NGC 7293 Jupiter, Saturn	Order: Saturn, Jupiter, Saturn in LiveView moda and in new EV planetary mode; M 27, M 2, M 30 partially obscured), M 15, NGC 7293 (Helix Nebula), NGC 6960, Jupiter, Saturn, IC 5070 (Pelican Nebula), IC 1396 (Elephant's Trunk), NGC 7023 (Iris Nebula), NGC 7000 (North America Nebula), NGC 6992, IC 1805 (Heart Nebula), IC 1848 (Soul Nebula), NGC 869 (h Persei), NGC 884 (chi Persei), NGC 633, NGC 457 (E.T. Cluster/Owl Nebula, already hazy), M 31, (M 33) Observation stopped because of haze.	eVscope 2, iPad	Observed between 6:30 p.m. up to 9:30 p.m.; 6:30 p.m. > SQM = 19.6; thereafter only small changes. One day after new moon. App: New version 2.2.0 with new planet EV mode; still a lot of bugs: the wrong (previous) object name is still displayed now and then; probably especially after connection loss, the icons next to the camera icon as well as the "edit/move" buttons disappear.
Dec 17 MH	OC: M 45 G: M 33, M 74, M 77, NGC 891 GN: NGC 1499	Order: Jupiter, Mars, Jupiter, Mars, M 45, NGC 1499 (California Nebula), Mars, M 77, M 74, M 33, NGC 891 Partially photographed at minute intervals to test the progress.	eVscope 2, iPad	Observed between 9:30 p.m. up to 0:10 p.m.; 0:00 a.m. > SQM = 19.6 (or about 19.6...) Planets poor, paticularly Jupiter (poor seeing?) App: New version 2.2.0 with new planet EV mode
