DwarfLab Dwarf mini - First Experiences

In progress

On this page, I describe my very first experiences with my electronic 30 mm refractor telescope Dwarf mini 30 mm/150 mm (f/5).

First Usage Notes

Photo: Dwarf mini during charging

Sammlung

Vorschau durch Weitwinkelkamera - man sieht auch, wie sich das Teleskop bewegt = neu ausrichtet

An der Powerbank lädt das DM nicht, mal zeigt es an, dass sie dran ist, mal nicht; am Computer lädt das DM, aber langsamer als am USB-C-Netzteil.

Das Bild wird irgendwie beim Stacken nicht oder nur kaum besser, seltsam...

First Observations

In the following I describe my very first experiences with the Dwarf mini from the first 10 observation sessions (Mühlhausen/Kraichgau).

Jan 15, 2026

M 33 (15 s, G 60, Astro filter) started shortly before 7 p.m.; aborted after 180 stacked subs (45 min) at about 7:50 p.m. because of fog; SQM mot measured, because of fog, and I was too late...
Re-start shortly before 9 p.m.with M 42/43 (15 s, G 60, DuoBand filter); stopped after 150 stacked subs (37.5 min) at 9:44 p.m.; fog, resulting photo rather washed out, but there were clouds in that area...

NGC 7000/IC 5070 (15s, G 60, Astrof ilter) started at 18:07/18,45 (instead of NGC 7000 the star HD 199457 was lited - I had moved the section a little bit...; 6:45/19,7 p.m./SQM, foggy; the result was rather poor after 120 subs; stopped after 241 stacked subs (60 min) at 7:24/19.81 p.m./SQM; foggy...
NGC 1499: First attempt failed at 7:33 p.m.; new attempt, observation started at 7:50/19.69 p.m./SQM; aborted at around 9 p.m., because nothing happened due to clouds (we had supper at that time...); 230 subs, but only 129 were stacked (32 min), stacking was done only until 8:28 p.m.; the battery went down to 17%.

Start at about 8:00 p.m., everthing rather chaotic... SQM was 19.78 at aroung 9 p.m., the sky was fairly clair this night
I trained the EQ and mosaic modes on NGC 1499 and NGC 2024/B 33; the EQ did not succeed, but the observations were OK, why ever...
NGC 1499 (30 s, G 60, DuoBand filter): Mosaic with 2 panels, observed from 8:29 to 21:37 p.m.; 50+50=100 subs (25 min)
NGC 2024/B 33 (30 s, G60, DuoBand filter): Mosaic with 2 panels, observed from 10:00 to 11:07 p.m.; 50+50=100 subs (25 min); SQM was 19.89 at 22:24 p.m.

Since mosaics are only optimally assembled with Stellar Studio, I do not show any unedited images.

Notes:

I first practiced EQ and mosaic modes on NGC 1499 (later on NGC 2024 and B 33). Therefore, no proper documentation... I seem to have placed the Dwarf mini in the opposite direction on the tripod (compared to the DwarfLab video, which I could not quite understand at first). But that does not matter, as I later learned from DwarfLab...
First, I aligned the head at 41° (90°-49°)* and then aligned the Dwarf mini to the north using the compass app on my iPhone. The app tested the alignment and reported that it needs to be corrected. I tried to do that, but it did not work; I tried that several times, but it never worked...
*) According to the angle scale, that was correct...
I then started observing NGC 1499 anyway, selecting a 1:1.8 mosaic consisting of two panels. The observation then started and switched back and forth between the two panels. However, the switching took forever (several minutes)...
In between, I occasionally encountered massive connection problems... At some point in time, it continued again.
I still have problems with adjusting certain things (EQ mode, mosaic mode, etc.).
The mosaic could not be improved with Stellar Studio (problems in China). It only worked the next day...

Jan 22, 2026

Photographed the crescent moon at about 5 p.m.. Took photos with 20, 38 and 50 subs, which were stacked. Post-processed some stacks in Stellar Studio.

Photos see page Observations of the Moon.

Jan 23, 2026

Photographed the crescent moon at about 8 p.m.. Took photos with 2x20, 1x50 subs, which were stacked. All stacks were post-processed in Stellar Studio.

Photos see page Observations of the Moon.

Jan 24, 2026

Photographed the crescent moon at about 6:15 p.m.. Took photos with 1x20, 1x50 subs, which were stacked. All stacks were post-processed in Stellar Studio.
M 15 (15 s, G 60, Astrofilter), attempted from 6:33 p.m., low on the horizon (19°, nearly in a tree), sky rather bright; (6:45/18.6); aborted at 7:07 p.m., M 15 was in a tree for a long time... 109 stacked subs (27 min)
NGC 1555 attempted at 7:16:p.m., but was still behind a house...
M 34 (15 s, G 60, Astro filter): 7:33/19.16 p.m./SQM, moon alread quite bright; aborted after 140 subs (35 min) at 8:07 p.m.; turned Dwarf mini off, because the battery was low...
NGC 752 (C 28) (15 s, G 60, Astro filter): Start at 8:17/19.07 p.m./SQM; aborted after nach 90 subs (22.5 min) at 8:43 p.m.
9:15 p.m.: Powerbank connected
NGC 891 (15 s, G 60, Astro filter): Start at 9:19/19.22 p.m./SQM; galaxy (small) hard to recognize in the beginning; stopped after 182 subs (45.5 min) at 10:15 p.m.

Photos of the moon see page Observations of the Moon. I restacked M 15 to eliminate disturbed photos. Here, I only show the restacked photo. This time, I only present the photos in their post-processed versions.

Feb 5, 2026

Photographed the sun in the afternoon (at about 3 p.m.) 4Took 4x photos with 20 subs each, which were stacked; post-processing with Stellar Studio brought no improvement...

Photos see page Observations of the Sun.

Started the Dwarf mini in EQ mode around 7:45 p.m.. At the beginning, I did not understand the instructions for the corrections: when the advised "higher", it meant "lower" (reducing the angle). During the first correction I made the angle larger and the error promptly grew from 9° to 14°. Then I tried the other way around and suddenly I was within 2° ;) So I was ready for the observations!

Started observations with M 31 in EQ mode as a 1:1.8 mosaic at about 7:50/19.6 p.m./SQM (15/60/Astro); stopped at about 8:40 p.m.
New attempt at M 31 in EQ mode at 8:42/19.7 p.m./SQM with 30s (30/60/Astro) as a 1:1.8 mosaic; aborted, because 30s did not work (because of automatisc parameters)
At about 9 p.m. attempt at M 45 in EQ mode as a 1:1.8 mosaic; this time, 30s worked (30/60/Astro; autom. param. off); stopped at 10:15 p.m.

Thereafter, I stopped my observations because of clouds...

Feb 7, 2026

Started in EQ mode a 2-panels 1:1.8 mosaic for M 42/43 at about 7:30 p.m. (Coal Car Cluster down to Jewels) (30/120/Astro; 50 subs per panel); SQM 19.8; stopped at 8:41 p.m.
Started in EQ mode a 2-panels 1:1.8 mosaic for NGC NGC 2237/2244 at about 8:50 p.m.(30/120/Astro; 50 subs per panel); 9:06/19.99 p.m./SQM; stopped at 10:02/19.99 p.m./SQM.
Started in EQ mode a 2-panels 1:1.8 mosaic for NGC 2264 at 10:10/19.99 p.m./SQM (30/120/Astro; 50 subs per panel); stopped at 11:19 p.m.

Thereafter, I stopped my observations because of clouds...
