At 300mm f/4 with M43 sensor.

Amazing stuff all! How did I miss this thread! 
What is that? Also which camera and lens? Settings? I have 3 m43 bodies but max 42.5mm focal length (85mm FF eg), can I still shoot something like this?
This is sooo good. How did you do it? Where did you do it? I would love to try my hands too.
You could do it, if you check the post which I replied to, it was shot with a 85mm full frame lens. Just that it wonât be zoomed in like this. Camera doesnât matter for the most part, as itâs a stack of ~100 images done in Siril, itâs a bit complicated software but itâs free and opensource. Iâm still figuring out how to use it.
Make sure you get a tripod(any basic tripod would do), as you need at least a few seconds of exposure, so even if you have super steady hands, holding it with hands for a few hundred shots is going to be PITA. If you live in heavily light polluted areas you might want to use filters that cut out the lights. I personally have no experience with them as the light pollution levels here are manageable.
You have to mess around with the settings to figure out the best parameters for the particular scenario, itâs affected by many factors - light pollution, phase and position of moon, cloud cover, visibility, fog etc. I usually spend the first 20mins trying out different settings before I actually begin shooting.
Thanks, you do it by taking a lot pics and stacking them over one another using some software (like siril) and processing it. Orion is decently bright enough so if you happen to live in a area without much light pollution, you could even get away by using the zoom lens in modern flagship phones (manual settings, raw mode) with a tripod.
But if youâre serious about astrophotography, Iâd very much recommend getting a sky-tracker and a semi decent telescope if you donât already have a telephoto lens (or if you have a wide angle lens you could do milky way or time-lapse shots).
If you like visual astronomy, get a dobsonian telescope, they are pretty cheap (compared to other options), very easy to operate (you just push it around) and gives some excellent visual experience for the money. You can also do some lucky imaging with bright objects like planets and moon.

Is that black spot on Jupiter the Great Red Spot?
I think itâs the shadow of one of its moons.
I know next to nothing about astrophotography. You will need to help me out here.
Do you have any shots of galaxies merging together? Please post them on this thread when you find the time. I personally find galaxies merging together to be incredibly fascinating!
Thank you. Siril looks really cool. I donât understand how you got 300mm focal length with an 85mm FF lens on an m43 sensor? The crop factor is 2x.
Also, nice shot of Jupiter! Does it actually look like that with the mentioned telescope, can we see this with our own eyes, or is this what the camera sees but is not visible to the naked eye?
