Tonight's post and image are a continuation of last night's post:
universeodon.com/@KrajciTom/11

(Winter milky way in Taurus - network of dark dust clouds. (85mm, f/1.4. Sony a6300.))

Tonight's image is monochrome/black & white because it's near infrared. (The filter is 670 nanometer long pass, which is very deep visible red (redder/longer than hydrogen alpha at 656 nm) and longer wavelengths, but my camera's sensitivity drops off and eventually ends at around 1050 nm)

Compare it to last night's color image. The infrared image can see deeper into some of the dusty areas that look quite dark in visible light.

Note that the infrared image is less sharp. The stars are bigger/fuzzier. That's because of chromatic aberration. This camera lens was designed to work well with visible light. It's performance in IR is noticeably poorer.

Can you spot the five Herbig-Haro objects (HH 7–11) in this #astrophotography image?!

This is NGC 1333 (a reflection nebula in the #constellation #perseus). The Herbig-Haro objects are the bright blue patches below -- learn more: en.wikipedia.org/wiki/Herbig%E

while not necessarily #SpookyAstrophotography -- I kinda see a human-like figure in this one....

We also did episodes on the #mythological stories of Cassiopeia, Andromeda, & Perseus (technically, we also covered Cepheus, but... also we didn't...), and you can find these #myth episodes here: starrytimepodcast.com/episodes
