Deep Sky Spring Observations July/August 2020

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

In July and August 2020, I did simple "deep-sky summer observations," which might be of interest to other beginners and are therefore described here. They took place in Mühlhausen/Kraichgau and in Erkerode (near Braunschweig).

List of observed deep sky objects (the links lead to pages describing the DSOs):

I selected the observation objects primarily on the basis of my literature (see references).

Observation Time

The observations were done in July to August 2020.

Observation Location

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

... and partly in Erkerode (near Braunschweig, Germany):

Devices Used

I used the TLAPO1027 on the AZ4 mount, the PS72 and the Skymax-127 on the AZ Pronto mount, and the C8 on the AZ4 mount

General Conditions

In Mühlhausen/Kraichgau, the sky was not particularly dark. In Erkerode, it was a bit better.

Jupiter, Saturn
GC: M 3
PS 72/432 and TLAPO1027: M 3 observed with about 100 x (4 mm at PS72, 7 mm at TLAPO); clearly brighter and more detailed in the TLAPO. Later, I observed Jupiter and Saturn.   PS72 on AZ Pronto, TLAPO1027 on AZ4

Jupiter, Saturn, C/2020 F3 (NEOWISE) We observed the comet C/2020 F3 (NEOWISE) on the Heiligenstein hill with the naked eye, all our binoculars, and the SM127 on AZ Pronto; the tail looked nicest in the binoculars. Also photographed the comet with the Sony RX10 M4 on a photo tripod.
Moreover, we observed briefly Jupiter and Saturn with the SM127 (32 mm, 10 mm).

C/2020 F3 (NEOWISE) Observed the comet C/2020 F3 (NEOWISE) with view to Braunschweig/mistle tree (at the end of the street "Über dem Steinbruch", at the edge of a field) using TS binoculars and photographed it using my Sony RX10 M4 on AZ Pronto (from briefly before 11 p.m. on); the tail was nicest in the bicoculars. After that, we observed the comet from the street in front of the house using TS and LT binoculars (about 11:30 p.m.).   TS and LT binoculars; Sony RX10 M4 on AZ Pronto 32, 10 mm

Jupiter, Saturn, C/2020 F3 (NEOWISE)
GC: M 4, M 5, M 9, M 10, M 12, M 14, M 80, M 107
OC: M 11
We observed the comet from the street in front of the house using TS and LT binoculars several times (beginning from 11 p.m.)
Observed globular star clusters from the balcony using the SM127, particularly in Scorpius and Ophiuchus: M 4 very faint, M 80, M 4 again, and very faint as well, M 107 not found, M 9, M 107 now faint, M 14, M 12, M 10, 107 again, very faint.
Finally, observed Saturn (ring) and Jupiter (1 moon to the left, 3 moons to the right) from the balcony (briefly before 1 a.m.).
TS binoculars: M 14, M 10, M 12, M 5 (no more found with SM127, to far in the West)
TS binoculars: chain on "nebulae" in the Milky Way, which I took for clouds first; wandered from top to bottom and saw 5-6 (or more) "nebula-like" objects: M 11 with a trapezium on top, below several nebulae (M 16-18?) of different sizes, perhaps M 24 and M 23 next to it, at the bottom a broad nebula stripe with many brighter stars in it, probably the Trifid Nebula M 20 and/or the Lagoon Nebula M 8.

MH
GC: M 13
OC: M 11
SM: Cr 399

PS72 compared with TLAPO1027 using some DSO:
M 13 observed with 16/26 mm, also nice in the PS72, stars nearly resolved in the APO... Also nice with 7/10 mm = 60/70 x; somewhat brighter in the APO...
Cr 399 (26/40) = 16.6/17.85 > fine stars, a little larger in the APO
M 11 (26/40) = 16.6/17.85 > faint glow, a little larger in the APO (found via star chain at the end of constellation Eagle, trapezium) >> the more than half moon was already to bright...
(Also compared using the using the moon, Jupiter, and Saturn)
All in all, the TLAPO1027 was clearly better (details elsewhere)...

PS72 compared with TLAPO1027 using two DSO:
M 13 with different eyepieces; somewhat brighter in the APO at higher magnifications
