#IC342: Hidden #Galaxy in #Camelopardalis
#Astronomy #Picture of the Day
Comparing the same part of the autumn Milky Way in blue and near-infrared light.
The first photo is in near-infrared, and the second is blue (from last night).
Near-infrared is less affected by interstellar dust and can 'see into' thick dust more than blue light.
This is a continuation of:

Gazing into the abyss of the autumn Milky Way between Perseus and Camelopardalis.
This monochrome image was taken in blue light, which accentuates the presence of interstellar dust.
The first image was plate solved, and you can see the results here:

The second image is a crop of the first image, centered on the darkest dust clouds where stars are almost completely absent...at least in blue light. (Infrared would be a different matter.)
The darkest clouds are Barnard nebulae 9, 11, 12, and 13.

The 3rd and 4th graphics show some objects in the frame, and the location of the photo in the larger context of the autumn sky.

#PhotoOfTheDay: #Hubble Images a Peculiar Spiral
A beautiful but skewed spiral galaxy dazzles in this NASA/ESA Hubble Space Telescope image.
The galaxy, called Arp 184 or NGC 1961, sits about 190 million light-years away from Earth in the constellation #Camelopardalis (The Giraffe).

NGC 1501 Blue Oyster Nebula
The Blue Oyster is a planetary nebula, representing an aging star that has shed its outer layers. Unlike the other planetary nebula, however, the central star of the Blue Oyster is not a typical white dwarf, but has a
spectra more like a Wolf-Rayet Star. In photographs, the magnitude 14.5 central star suggests a pearl inside a blue oyster.

IC 3568 Lemon Slice Nebula
Magnitude 12.3 planetary nebula located 4,500 light-years away in the constellation Camelopardalis. It was discovered on August 31, 1900 by the American astronomer Robert Grant Aitken while using Lick Observatory's 12" Clark Refractor. This was confirmed with the observatory's 36" Refractor the next night.

Homebrew Radio Telescope Bags Pulsar
When one mulls the possibility of detecting pulsars, to the degree that one does, thoughts turn to large dish antennas and rack upon rack of sensitive receivers, filters, and digital signal processors. But there's more than one way to catch the regular radio bursts from these celestial beacons, and if you know what you're doing, a small satellite dish and an RTL-SDR dongle will suffice.
Granted, [Job Geheniau] has had a lot of experience exploring the radio universe. His website has a long list of observations and accomplishments achieved using his "JRT", or "Job's Radio Telescope." The instrument looks like a homebrewer's dream, with a 1.9-m satellite TV dish and precision azimuth-elevation rotator. Behind the feedhorn are a pair of low-noise amplifiers and bandpass filters to massage the 1,420 MHz signal that's commonly used for radio astronomy, plus a Nooelec Smart SDR dongle and an Airspy Mini. Everything is run via remote control, as the interference is much lower with the antenna situated at his family's farm, 50 km distant from his home in The Hague.
As for the pulsar, bloodlessly named PSR B0329+54, it's a 5-million-year-old neutron star located in the constellation of Camelopardalis, about 3,500 light-years away. It's a well-characterized pulsar and pulses at a regular 0.71452 seconds, but it's generally observed with much, much larger antennas. [Job]'s write-up of the observation contains a lot of detail on the methods and software he used, and while the data is far from clear to the casual observer, it sure seems like he bagged it.
We've seen quite a few DIY radio astronomy projects before, both large and small, but this one really impresses with what it accomplished.
