Here are my results imaging the area around the Auriga Consteleation. Joined 2 mosaic images to get 1 big image, this time with the light pollution filter. On the bottom left you can make out with its open . On top right you can see . This time you can see the nebula - tinted red though. Below is yesterday’s image. Tomorrow will try again with my new glass filter.

Continuing to test the results of the using the Optolong Moon SkyGlow 2" Mounted Filter, decided to go relook at - . First set of images are using the filter from last night. Not a perfect comparison as the first set of images were a 23+ minutes observation with 20 second exposures, while the second set is at 27+ minutes observation with 10 second exposures. The latter seem a bit over exposed I feel.

Received in the mail yesterday a Optolong Moon SkyGlow 2" Mounted Filter for the s50. Also purchased a dew shield (with additional accessories) on Etsy. Here is a comparison test between the actual filter and the s50 onboard light pollution filter. Test subject - .

NGC 6888 The Crescent Nebula - telescope processed image. Definitely less red than the earlier images, but missing some detail. Looks like longer exposures time is needed. 20+ image using 20 second exposures. NGC 6888 The Crescent Nebula - unprocessed image. Less red in this new image. This is a 20+ minute exposure with 20 second exposures. NGC 6888 The Crescent Nebula - telescope processed image. The onboard denoising seems to amplify the red color more. 20+ duration image using 10 second exposures. NGC 6888 The Crescent Nebula - unprocessed image. Using just the s50 onboard LP filter, more reddish tones. Took this 20+ minute image in 10 second exposures.

Me gusta estar en contacto con los desarrolladores de #apps.

Recién inicié un buen intercambio de experiencias con John Stephen, creador de #LuminosPro, una de las mejores aplicaciones para #astronomia que disfruto mucho de usar en el #iPadPro. Es probable que en un par de versiones mas, se pueda interconectar el #SeeStar a esta app, y controlarlo desde ahi. Por lo pronto, ya le di argumentos para comprarse un S30.

Looking in the sky atlas portion of the s50 app and noticed this area around the Auriga Consteleation. Thought this would be a nice opportunity if a large mosaic. Well, forgot to put on the light pollution filter. Still this is a nice starfield image that I can use for comparison later. On the bottom left you can barely make out with is open . On top right you can see . Both have around them.

AE Aurigae & NGC 1893 - telescope processed images. AE Aurigae is a runaway O-type star that illuminates the Flaming Star Nebula (IC 405) as it speeds through space. NGC 1893 is a young open cluster embedded in the nearby Tadpole Nebula (IC 410).

Here is a better image. Captured the . Almost 45 minute duration observation.

Good Wednesday morning. Left the s50 out this morning to get some more observations before the weather turns bad again. First up is . Not a very impressive picture - 216 stacked images at 20 seconds each. Galaxy is barely visible. In the unprocessed image it seems that the Andromeda Galaxy may be affecting the imaging.

NGC 7640 galaxy - telescope processed image. NGC 7640 is a barred spiral galaxy in the constellation Andromeda, about 30 million light-years from Earth. It was discovered by William Herschel in 1786. NGC 7640 galaxy - unprocessed image. It's a barred spiral galaxy in Andromeda that's often "overlooked" because it shares its sky with the much bigger and brighter Andromeda Galaxy (M31).

Never believe the cloud forecast. The only clouds are hydrogen clouds ;-)

Anyhoo, Orion is back in the morning sky and therefore the horse head nebula is too!

#astrophotography #space #seestar #astrodon

A softly glowing red cloud of gas behind the dark sharp edge of a foreground dust cloud. Part of the dust looks like the silhouette of a horses head. 

Below it sit an orange nebula shaped a bit like a
flame or upside down drop, with a bright star next to it.

So I answered my question from yesterday of what a whole night observation of with th s50 would look like. From 7:30 PM to 4:30 AM. 1221 stacked 20 second exposure images. The last image shared is an observation of the Iris Nebula from April 2025.

NGC 7023 The Iris Nebula - s50 telescope processed image.  Compared to last morning’s image, there seems to be more details with the nebula clouds. Background is not as dark though. NGC 7023 The Iris Nebula - s50 unprocessed image.  Even without the denoising, more star details seem to come through. NGC 7023 The Iris Nebula - telescope processed image from the Odyssey Pro from April 2025. 24 minute duration.

Last observation on the s50 planner from last night. Here is .

NGC 1491 The Fossil Footprint Nebula - telescope processed image.  It's a glowing emission nebula in Perseus (~9,800 light-years away). Its gas is ionized by a massive central star that creates a "footprint" shape.  NGC 1491 The Fossil Footprint Nebula - unprocessed image.  A bright star, BD +50 886, sits in its core! Its powerful stellar wind is carving out the "footprint" shape by blowing a bubble in the gas.

The second observation from last night on the s50 is . This image also makes me wonder what the results would be of leaving it overnight.

IC 5146 The Cocoon Nebula - telescope processed image.  IC 5146, the Cocoon Nebula in Cygnus, is a stellar nursery (~15 light-years wide) with emission, reflection, and dark nebulae where new stars are forming. IC 5146 The Cocoon Nebula - unprocessed image. It gets its name from being a bright emission/reflection nebula surrounded by a dense, dark cloud (Barnard 168), like a cocoon hiding new stars.

Good Monday morning. Left the s50 outside yesterday performing 3 observations. First of these observations is - yes again. This time the stack duration is 843 images. Still make me wonder what would show if I left it out all night viewing this nebula.

NGC 7023 The Iris Nebula - telescope processed image.  NGC 7023, the Iris Nebula, is a beautiful blue reflection nebula in Cepheus, about 1,300 light-years away. Its dust reflects light from a central star.NGC 7023 The Iris Nebula - unprocessed image.  This beautiful reflection nebula glows blue as dust reflects the light of its central star. Its "petals" of cosmic dust make it resemble an iris flower.

Globular cluster NGC 2419 is nicknamed the Intergalactic Wanderer because, at 300,000 light years away, it was once thought to not be orbiting the Milky Way. Instead, its orbit takes about 3 billion years. #astrophotography #seestar #ngc2419
