Deep Sky Summer/Autumn Observations September - Mid-October 2019
Conditions | Observation Overview | List of Observed Sky Objects | References
In September 2019 up to the beginning of October, I did simple "deep-sky summer / autumn observations," which might be of interest to other beginners and are therefore described here. They took place in Sumène, Haute Loire, France, and were carried out with a borrowed Sky-Watcher StarTravel 120/600 refractor, my Omegon Photography Scope 72/432 refractor and with my binoculars.
In mid-October 2019, I observed some selected DSO with the borrowed Sky-Watcher StarTravel 120/600 refractor, my Omegon PS 72/432 refractor, my Sky-Watcher Explorer 150PDS Newtonian tube, and my Sky-Watcher Skymax-127 Maksutov-Cassegrain tube for a comparison of the telescopes; I add these observations to this page.
Note that more than 20 of the about 50 observation objects were new to me:
- Kemble's Cascade, M 9, M 14, M 19, M 107, M 4, M 80, M 26, M 18, M 21, M 22, M 23, M 24, M 28, M 54, M 55, M 69 , M 70, M 75, M 76, NGC 7000
Conditions
Sky Region and Objects
I observed in various sky areas as shown in the sky maps below.

Observation Time
The observations were done in September/October 2019, typically after 9 p.m. and up to 11 p.m. or shortly after midnight (once).
Observation Location
The first series of observations took place in Sumène (close to Saint Julien-Chapteuil), Haute Loire (France):
- Coordinates: 45° 2′ N, 4° 4′ E
- Coordinates (dec.): 45.04° N, 4.06° E
The observations in mid-October 2019 took place in Mühlhausen/Kraichgau (Germany):
- Coordinates: 49° 15′ N , 8° 43′ E
- Coordinates (dec.): 49.25° N, 8.72° E
Devices Used
In France, I used my Leica Trinovid 10 x 25 BC binoculars (LT binoculars), my TS 10 x 60 binoculars, my Omegon 2.1 wide field binoculars (OM21), a borrowed Sky-Watcher StarTravel 120/600 refractor and my Omegon PS 72/432 refractor. I used my UWA eyepieces (7 mm, 4 mm), a Televue Delos 10 mm eyepiece, and a 24 mm Televue eyepiece for a maximum overview. Sometimes, I also used a TSED35 eyepiece (2", 35 mm focal length, 69° angle of view) and a borrowed TSWA32 eyepiece (2", 32 mm focal length, 70° angle of view). So this time I observed "manually" without any GoTo control!

In mid-October 2019, I with the borrowed Sky-Watcher StarTravel 120/600 refractor, my Omegon PS 72/432 refractor, my Sky-Watcher Explorer 150PDS Newtonian tube, and my Sky-Watcher Skymax-127 Maksutov-Cassegrain tube for a comparison of the telescopes. I used eyepieces in a manner to achieve a similar magnification (which was not always possible).
General Conditions
The sky above Sumène, Haute Loire (France) is relatively dark (the Betz observatory used by the Orion43 group is near-by). The milky way could be seen very well at times. In Mühlhausen/Kraichgau, the sky was not as dark as in France.

| Sep 17 | G: M 31 (Andromeda Galaxy) P: Cr 399 (Coat Hanger) OC: Mel 20 (Mirphac Cluster), NGC 884/869 (Perseus Double Cluster), M 11 (Wild Duck Cluster) |
OM21: M 31 small, Cr 399 seen just "half" and
with viewing indirectly, Mirphac cluster seen, Perseus Double Cluster seen
as a glow. Wandered along the sky; Dolphin, Cassiopeia seen as entire constellations; saw several "asterisms" (pattern like structures). All in all, the stars were much better to see than with the naked eye, but the sky background was quite bright... LT/TS: M 31; Cr 399, M 11 seen with "trapezium"; Mel
20; NGC 884/869 seen with "oval". |
Observations with OM21, LT and TS binoculars; a nice sky overall at about 9 p.m.; around 10 p.m. the moon was too bright | OM21 binoculars, LT and TS binoculars | |

"Comparison observations" with my PS 72/432, a few new objects. At about 10:15 p.m., the sky was still very dark (I thought that the moon would disturb, but that was not the case...). I saw even M 31 (more indirectly) and the Perseus Double Cluster with the naked eye. |

Observations with the ST120
Andromeda: M 31 (24, 7, 4 mm) very nice; seen or guessed
with the naked eye. Scutum: M 11 found by chance... Sagittarius |
The sky did not seem as dark to me as the day before, but I could still see the Perseus Double Cluster and M 31 with the naked eye, before the sky, probably due to the moon, got brighter again. | ST120 on AZ Pronto | UWA 4 mm, 7 mm, 16 mm; WA 24 mm |

Observations with the ST120
Scorpius: M 4 (24, 10, 7, 4 mm): very low, very faint, with 4 mm probably resolved a bit into stars; M 80 (24, 10, 7, 4 mm): low, but a little higher up than M 4; somewhat brighter, small, between two stars (vertical line), with 4 mm perhaps resolved in to stars... Ophiuchus Sagittarius Scutum: M 11 (24, 10, 7, 4 mm): Very nice at all magnifications. |
New Moon; observed mainly globular cluster in constellation Ophiuchus. | ST120 on AZ Pronto | UWA 4, 7, 16 mm; WA 10 mm, 24 mm; 32 mm Plössl (initially) |
| Sep 29 | GC: M 13 OC: NGC 884/869, NGC 663? Planets: Jupiter |
Observations with the ST120 At first I thought that I would be able to continue my observations in the SW, but after dinner the sky was covered there. There were holes at Cassiopeia, where I tried to compare the 32 mm and 35 mm 2" eyepieces. I also walked along the sky a bit there. In between, a jump to Hercules, when Cassiopeia was covered, then back again, when Hercules was covered... An evaluation of the two eyepieces was difficult for me, especially since clouds often appeared when I wanted to test the other eyepiece. Shortly before 10 p.m. observations were no longer possible, and I ended my observations. I was still able to observe (with both eyepieces, no difference detected):
Everything looked nice, but was still relatively small (about 17 x / nearly 19 x, that is, twice the size as in 10 x binoculars). Jupiter seen at low magnification , 4 moons (Jupiter only used as search aid). |
Comparison of the 32 mm and 35 mm eyepieces (2", with 2" zenith mirror). Cloudy sky, which forced me to stop my observations. The 35 mm eyepiece can just be brought into focus! There is no room for fine focusing. |

Observations with the ST120
Scorpius: M 4, M 80 (24, 10 mm) very low, particularly M 4 faint; M 80 somewhat better Ophiuchus: M 19 (24, 10, 7, 4 mm) had 3 stars on top of it, 2 to the right (= left) of it -> for identification - somewhat larger, faint, because low; not resolved; M 14 (24, 10, 7, 4 mm): was accompanied by three stars and a triangle -> for identification; small, faint at 4 mm, not resolved. Sagittarius Scutum: M 11 (24, 10, 7, 4 mm) very nice as always; M 26 (24, 10, 7, 4 mm) forms an obtuse triangle with two other stars, saw only few stars, but there should be 30 and more... At the end, I observed M 45, Mel 20, NGC 884/869, and M 31 with the 35 mm ED eyepiece; all were very nice; M 31 without structure, but with a bright core. Planets |
With that I probably had found all accessible lower DSO in the southwest; M 6, M 7, and M 62 did not seem to be accessible anymore. | ST120 on AZ Pronto | UWA 4, 7 mm; WA 10, 24 mm; TSED35 |

Observations with the ST120
Sagittarius Hercules: M 13 and M 92 seen well ; M 13 nearly from 10 mm on resolved into fine stars, but definitely from 7 mm on; M 92 from 7 mm on resolved into fine stars. 35 mm ED Eyepiece (together with Astrid) Lyra Sagitta: M 71 (24, 10, 7, 4 mm) somewhat resolved at 4 mm, nice, but faint Cygnus Vulpecula Perseus Andromeda Cassiopeia Triangulum: M 33 (24, 10 mm) was still a glow, but more distinct than ever before...

M 42/43, M 45, M 35 | Comparison StarTravel 120/600 with 10 mm Delos eyepiece (60
x) and 2" zenith mirror versus PS 72/432 with 7 mm UWA eyepiece
( 62 x) and 2"-to-1.25" Amici prism Due to a lack of suitable adapters, I had to use the Amici prism for simultaneous observations. Orion Nebula M 42/43 (60 x): After the telescopes had dried in the morning, the nebula was visible, but not as good as I have seen it already sometimes. Especially, Astrid found the nebula in the ST120 much better - the larger aperture paid off. After the drying, the trapezium could also be seen well in both telescopes, including the 4th weaker star. In the ST120 the upper and lower star in the sword just fit in at the edges (there were probably more than one); in the PS72 I did not check that... Orion Nebula M 42/43 (nearly 20 x with
32 and 35 mm 2" eyepieces): I was not able to find any differences
between the two eyepieces. However, the trapezium, which was now tiny,
was slightly better visible in the 32 mm eyepiece of 32 (like a star with
ears...); probably due to the slightly higher magnification of 18.75 x
versus 17. 14x. Further Targets: M 45 (Pleiades) were beautiful with 35 mm
and probably also with 32 mm eyepiece. Various targets seen with LT and TS binoculars: M 42/43, M 45, M 35 |
The evening before (Oct 11) I set up the telescopes and briefly
observed Jupiter and Saturn with them (60 x). In the morning they
were full of dew and had to be dried at the eyepiece and lens (the ST120
was a bit better because of the large dew cap, but also not free of dew).
Observation time approx. 4:50 to 5:50 o'clock on Oct 12 early in the morning. At the beginning, the moon was still visible, later its light still disturbed a little, although it had already set. Altogether, the situation in the morning became more and more unfavorable now, because the moon set later and later. The telescopes were fogged over after the observation, and therefore I left them in our winter garden; they were still wet in the morning. The ST120 was inside, probablyfogged over on the rear lens, and I let it dry up at noon for several hours outside and partly in the sun without a lid and open at the back. At first the thicker dew disappeared, but then the fine one as well. Thereafter, I packed it in its bag (after 2 - 2.5 hours). | ST120 on AZ Pronto, PS

Clear sky, upcoming clouds at the end...
On this day, as well, the sky became a little better in the course of time, but cloud strips came again and again, and at the end, clouds came in from southwest. >> The test actually went as expected: the Explorer 150PDS probably had some advantages compared to the ST120 (this was mainly Astrid's opinion). Summa Summarum (October 12-16) The performance order seems to follow the "effective" aperture:
The Exp150 may be a bit better than the ST120, but it is not for travel! | ST120 on AZ Pronto mount, Explorer 150PDS on Star Discovery mount (manually; this time, it worked quite well!) | 10 mm WA, 16 mm UWA, 24 mm WA, 4 mm UWA, 7 mm UWA |
