C 27 - „Crescent Nebula“ oder Sichelnebel.
Das bleibt übrig, wenn ein Stern in einer Supernova explodiert. Die Schockwelle wird aber das weitere Gas in der Umgebung komprimieren, woraus neue Sterne entstehen können. Recycling.
Aufgenommen mit meinem #dwarf3 - ca 4 Stunden mit jeweils 30s Belichtungszeit. Nachbearbeitet mit #siril und #graxpert
This morning, as I emerge from a week of HMPV (a respiratory illness), I have an unusual (for me) treat.
Last night, while I slept, I had my #Dwarf3 up on the patio roof just outside the door to the games room I am isolating in. The games room is elevated, so the patio roof is at eye level. This makes it perfect for putting the telescope on, and then crawling into bed. The downside is that the field of view is quite limited, as the games room roof overhangs the patio roof by a goodly amount.
But the view to the North and East is not bad. And it turns out that, while Andromeda is blocked by the houses next door, #M33 is not.
Now here in Perth, it does not get very far above the horizon at the best of times, but last night I managed to snag an hour and a half of it.
(Edited to include what I've been sick with.)
So here we are: The #TriangulumGalaxy , Dwarf3 #SmartTelescope . Postprocessed in the #DwarfLab #StellarStudio, #Snapseed, and #GooglePhotos
Clear Skies and New Moon - you know what that means! It's #astrophotography time!
I left the #Dwarf3 out all night last night, but work today, so didn't get to process any. Here is the only one I did anything to this morning - the Eagle Nebula. 23 minutes using the Duo-band filter. Post processed with the 'Auto' option of Stellar Studio. Will probably re-do it tonight, but I really like this one.
IC 342 oder C 5, Galaxie der Maffei-Gruppe. Liegt nah an der Ekliptik der Milchstraße, deren Staub einiges an Licht schluckt. Daher wird sie im Englischen auch „hidden galaxy“ genannt.
1. Nacht ~180 Bilder je 60s mit Astrofilter

That's a lot of stars!
The Pacman nebula NGC 281 in Cassiopeia. Quite faint, only barely visible on a 45s sub. 632 X 45sec subs. Stacked in Stella studio on the #Dwarf3 #AstroPhotograpy
First "proper" target for the #Dwarf3 was Caldwell 20, the North America Nebula. Quite an easy target but got to start someplace! Processed a tad, using Stellar Studio and then Snapseed.
While waiting for the images to capture, I listened to dogs barking in the distance, a sheep in a nearly field, and _something_ snuffling around in the garden.
I've kind of missed the boat on the Rim Nebula, NGC 6188 this year, it's setting pretty early for me now, but last night I managed a few hours of it before it went down behind the buildings. With the right filter on this time. I'm pretty pleased with the result after some tinkering in Snapseed.
Das konnte ich mir nicht entgehen lassen, auch wenn das Wetter nicht ganz so mitgespielt hat. Immerhin, das Ende habe ich noch erwischen können.

Tja - wenn das Wetter mal mitspielt…
Sh2-155 oder C 9 „Höhlennebel“.
In mehreren Nächten insgesamt fast 6h mit verschiedenen Einstellungen mit meinem #dwarf3 ausgenommen und in #siril mit #starnet , #graxpert und #cosmicclarity nachbearbeitet…
For my second target last night, I revisited another old friend - the Sculptor Galaxy, aka The Silver Dollar, aka C65, aka NGC253.
This is amongst the largest of the spiral galaxies that can be seen from the Southern Hemisphere, and is a favourite of mine. This is nearly 5 hours exposure, gain 80, with just a light pollution filter on my Dwarf3. Postprocessing as usual in Snapseed after running through the in-app Stellar Studio tools.
This evening's first target was going to be a mosaic of two nebulae. Alas, I got the framing a little off, and I ended up with 1 1/2 nebulae. At the top is half of the Eagle Nebula (M16), and down the bottom is M17, The Swan/Omega/Check mark/Horseshoe nebula.
In between them are a cluster and two smaller nebulae.
3 hours and 10 minutes, in 60s frames, @80 with a Ha/OIII filter.
Last night we had a lovely clear sky, so I set up a mosaic with the Dwarf3 around the Triffid and Lagoon nebulae.
I applied my usual post processing steps, and I got almost as good a result as I got up in Beacon with the DwarfII. But only almost, and with twice as long an exposure.
Let's just look at that for a moment, because not all is as it seems.
The D3 has a 38mm aperture, and the D2 25mm. This means that the D3 has twice the light gathering capability of the D2, and has a more sensitive detector. So this image has four times the light gathered as the image in Beacon, but it is also a mosaic covering almost four times the area, so we come back down to the same amount of light per pixel as the D2 got in a true dark sky.
What this means is that if I had taken this shot last week in Beacon, it would have been truely spectacular!
2 hours 8 minutes total exposure, gain 80, Ha/OIII filter.
So got home from dinner last night and noticed as I was walking in that there is a clear sky. Checked the forecast and it was going to be ‘mostly’ clear all night so I got the ‘scopes out and whipped up a schedule on both.
A general lot of ok shots, but particularly pleased with this one of the lagoon nebula. (M8) Taken with a #dwarf3 50 minutes total exposure (15s frames). Post processing by the denoise built in feature and that’s it.

This was one of my targets on my trip out to the Wheatbelt town of Beacon this weekend! Here is my take on it, taken with a #Dwarf3 .
AstroDuet
Two Dwarf3 telescopes watch the sky turn above them. A satellite flies past.
What the phone sees vs what the Dwarf sees.
Last night was an interesting one for astrophotography. According to the forecasts, we were to expect about 2 hours of clear skies, and right on schedule, a mass of cloud came in from the North-West. Unexpectedly, it then slid off to the South-West, and vanished. We then spent the rest night nervously picking new targets and waiting for the cloud to return. Which it did at about 4AM.
So this was one night where having the ability to schedule our shoots was utterly useless to us.
That said, we are in Bortle 2/3 skies here, and with a new moon we had a chance to go for some things that lose a lot of detail in the suburbs, even with a smart telescope.
One of those for me was the Tarantula Nebula, aka 30 Doradus in the Large Magellanic Cloud.
This is a truly massive star forming region - don't forget that the LMC is a companion galaxy to ours - so it is really far away compared to other similar objects we can discern. As it is, it is 2/3 degree by 1/2 degree in size for us, making it a massive 200-570 parsecs across at the estimated distance of 49 Kpc .
It is also insanely bright - if it was the same distance as the Orion Nebula, it would be as bright as a full moon!
Anyways, I got 83 minutes with the Ha/OIII filter on the Dwarf3, post processed in Stellar Studio and Snapseed.
