Smartphone Astrophotography
Photographic sensors of electronic equipment are increasingly evolved. So much so that it is already possible to do astrophotography with some smartphones. And I decided to grab the opportunity! I placed the smartphone on the floor, leaning against a rock, manually focused on the stars and set the exposure time to 20 seconds with an ISO 3200. Here is a first landscape astrophotography experience captured in Messejana - Aljustrel, Portugal.
Smartphone: Huawei P20 Pro
Sensor: CLT-L29
F-ratio: f / 1.8
Exposure time: 20 sec.
ISO: ISO 3200

Sh2-129 and OU4: The Flying Bat and Squid in Cepheus
Astrobin link: https://astrob.in/ulpvtr/F/
Sh2-129 is a large HII region known as the Flying Bat nebula in the constellation Cepheus, at a distance of 2,300 light years from the Sun. The field of view presented in this image spans 2 degrees by 3 degrees, or 4x6 full moon diameters. Inside Sh2-129 is the Squid nebula (Ou-4), discovered in 2011 by French astrophotographer Nicolas Outters . The curious bipolar shape of Ou-4 led the original investigators to hypothesize that the Squid could be a planetary nebula and its size, if its position was confirmed inside Sh2-129, would make it the closest observed planetary nebula to Earth.
A more recent investigation confirmed the location of Ou-4 within Sh2-129 but argued against Ou-4 being a planetary nebula concluding “it is reasonable to suppose that Ou-4 is an outflow launched some 90,000 years ago from the massive triple stem HR 8119” (the bright blue star in the center of Sh2-129 and Ou-4 responsible for the radiation that makes both nebulas glow). In this paper there is also a detailed morphological description of Ou-4, including the multiple arc shape of the bow shocks at the Northern and Southern tip of the nebula, visible in the image presented here. In this scenario, the Squid Nebula would physically be 50 light years across.
In addition to Sh2-129 and Ou-4, in the bottom left corner of the image, reflection nebula vdB 140 can also be identified with some of the blue continuum signal passing through the OIII filter.
The data presented here is a combination of Ha and OIII narrowband images (HOO color palette) and RGB color for the stars.

The Veil Nebula
The source supernova was a star 20 times more massive than the Sun, which exploded around 8,000 years ago. The remnants have since expanded to cover an area of the sky roughly 3 degrees in diameter (about 6 times the diameter, or 36 times the area, of the full Moon).

Re: Submissions: 2019 September
This HaRGB composite image I just finished might not be Hubble quality, but given the fact that it was shot from my city garden, in one of the worlds most light-polluted countries (The Netherlands) I thought I'd give it a shot. At least I am pretty proud of my first astrophoto that caused my jaw to drop when I saw the stack results. The nebulosity of IC5070 and especially the ridge known as IC5067 popped out.
It was shot over 6 nights starting at August 22nd. I shot 9 hours and 12 minutes worth of images through an Astronomik 12nm Ha clip-filter and just over 12 hours worth of RGB using my DAW modified Canon 60D and a vintage Televue Pronto refractor. All was tracked on an iOptron CEM25p without guiding. I just eyeballed the polar alignment using the iPhone app "Polar Scope Align".
I used DeepSkyStacker 4.2.2 for stacking of all the material and Photoshop for post-processing. I learned the techniques needed by watching Youtube clips by Trevor Jones (Astrobackyard) and Dylan O'Donnell (Star Stuff).

Omicron Persei Cloud (Gingrich 1) B3/B4/B5/Ced20/Cr41/IC348/LBN758/VdB19 (c)
Total integration: 510m/8.5h (102 x 300s).
Camera: QH247C (24mp OSC) CMOS cooled to -15 degrees C.
Telescope: Takahashi FC100DF Steinheil fluorite doublet apochromat refractor @ f/4.9.
Reducer: Takahashi FC-35 2".
Mount: Paramount MyT.
Filters: 2" Baader UV-IR-Cut.
Software: TheSkyX Pro, Sharpcap, PixInsight.
Inline (small size) image is uploaded to the forum. Full sized image is via here: https://www.astrobin.com/i32wrg/
The Omicron Perseus Cloud is an open cluster that is associated with some nebulosity, including dark oily patches of dust that are illuminated by a tight cluster of stars. IC348 is the designation given to 2-million-year-old star forming region (seen in the middle) with roughly 400 members that is ~1000 light years away from us.
I'm fascinated by dark nebulae/regions of space and I've been wanting to image one that had more of a three dimensional oily quality to it, unlike my previous ones with the Cocoon, Iris, and Pleiades. From my observations, dark regions/nebulae can either look like they are embedded/embossed within the sky background (see Cocoon image: https://www.astrobin.com/414567/) or sometimes they can appear as swirls or clouds of dust around reflection nebulae (see Iris and Pleiades images: https://www.astrobin.com/413899/ and https://www.astrobin.com/421142/) and sometimes they can appear like an patch of oil. This nebula has all these types of dark regions (Barnard 3, 4, and 5) in the context of other reflection/emission nebulae, but the oily patch in centre-right (B3) is what attracted me to this target.
As the name suggests, this nebula/cluster is part of the constellation Perseus. Specifically the triple star system illuminating the dust is Omicron Persei, a binary pair of which are known officially as Atik (the top brightest blue one) and Ab. This nebula is part of the giant Perseus molecular cloud that is largely invisible (unlike the Orion molecular cloud) except for two star forming regions, this one and NGC1333 (also known as Embryo nebula). While not associated with this region, there are over a dozen small galaxies in the background some of which you can make out if you look closely.
The final images represent an integration of data collected over two nights. For the very first time, I had to use flat frames to remove some dust tracks/motes from somewhere in my imaging train for reasons that are not entirely clear. Normally I don't need them, but it could be due to the nature of target, since I had to bring up the background to highlight the dark regions or it could be due to my new settings. Either way, after some trial and error I made it work.
Aside from working on doing the calibration properly, there is nominal processing in the above image. An alternate version with more aggressive processing to highlight the dark nebulae is here: https://www.astrobin.com/i32wrg/B/

Imaging details if you care:
Captured in San Diego county desert at 3000ft elevation southeast of Mt. Laguna at the very end of August 2019.
Thirty - 60 second frames each of R,G,B with a cooled CMOS camera
Telescope: 254mm Corrected Dall Kirkham at 1700mm focal length at f/6.7
Raw image scale: 0.47 arcsec/pixel, this version was resampled down to 33% or ~1.5 arcsec/pixel

Hi all,
Here is a recent image captured by myself of Jupiter showing the GRS.
The image is a stack of derotated (Winjupos) RGB video captures.
Captured using Firecapture, stacked with Autostakkert, and derotated with Winjupos.
