#astrophotography thoughts

[eclipse-astro]

thought a little about how phones could be if we normalized astronomy more and there are so many cool options

imagine if you could open up your lock screen and it automatically was able to show the phase and position of the moon

imagine if every phone had a built-in full scale sky simulator (i imagine this would be by far the best sky simulator created, if it had the backing of a huge company like apple or samsung)

imagine if you could point your camera at a star or planet and the camera would automatically identify (this shouldn’t be too hard, if the phone has location and positional data) that star or planet and then give pictures and information about it

imagine if when you open your camera app and point the phone at the sky, the phone (at night) automatically showed that sky simulator overlayed on the sky in real-time with the full sky simulator controls (changing time, seeing how the sky looked previously and how it will look)

imagine if you could put your phone on a telescope adapter and set the camera on a telescope mode where it optimizes the camera for astrophotography (planetary, lunar, basic deep space, the works)

imagine if when you pointed your camera at the moon instead of overlaying a fake texture it just gave info about the rise and set times, current phase, distance from earth, etc- all with visual aids overlayed right on the live camera!

there’s an insane amount of potential here for Really Cool Sci-fi Stuff that we just. collectively decided not to explore?

this is probably true for literally any specific topic, if you know about any and have ideas feel free to reblog them or comment them or tag them or whatever you’re supposed to do here

Picture of the bubble nebula and surrounding objects : Top left (the vague group of stars): M52 an open cluster

Center right: NGC 7538 an emission nebula (also known as the northern lagoon nebula)

Bottom center: NGC 7635/the bubble nebula and the surrounding hydrogen cloud

The ''bubble'' part of this nebula is created by the stellar wind (flow of gas, plasma and particle) emitted by the central star at nearly 650 million km/h hitting and compressing the surrounding interstellar gas. The central star (BD +602522) is currently estimated to be about 45 times heavier than our sun and about 4 million years old. Being so massive and thus very hot (it's a type O star) its lifespan is very limited for a star and it should go supernova in about 10 to 20 million years.

BD +602522 is slightly off center from the bubble, this is due to the interstellar gas being a bit more dense on one side and thus slowing the stellar wind more efficiently.

Single exposure to make the central star more visible.

Image taken using a CarbonStar 150/600 newtonian telescope with a 0.95 coma corrector, ZWO ASI294 monochrome camera. 12x300s image for each colour filter (LRGB) and 12x300s for the Ha filter, total imaging time 5h, stacking and processing done in PixInsight.

Starless version of the same image:

The first photo shows the Sun's chromosphere in stunning 250MP 8K. This is the hydrogen alpha wavelength and requires a very narrowband filter that notches out every other wavelength except Ha. In this view you see solar flares, prominences on the limb and surface activity. The second is a photo of the Sun's photosphere, which is the view we get using a regular broadband filter. In this view, we see sunspots, granulation and faculae.

The sky is so tragically beautiful, the graveyard of stars.

This is a picture of the hydrogen and dust cloud surrounding the star Sadr (the bright white dot near the center) also known as IC 1318. The bright parts represent hydrogen clouds and the dark parts dust clouds. Those types of clouds are the birthplace of new stars. This particular photo is in black and white because it was made by using a filter that lets only the light emitted by ionised hydrogen (the H alpha spectral line) pass through it. This increases the visibility of the hydrogen clouds. Since this light is at 656 nm, it would appear bright red if coloured. Together with H beta (496 nm) also from hydrogen and O III (around 500 nm) from oxygen both cyan in color, they represent the majority of light emitted by gas clouds. So in conclusion if you were able to see this gas cloud directly it would appear a reddish-magenta color (H alpha being the dominant emission).
