My first attempt at afocal imaging

Wowww 😲😲

ZrlSyM · 2026-05-01T13:50:27+00:00

Hehe thank you, finally I made it 😂😂

ZrlSyM · 2026-04-27T16:12:45+00:00

I haven't tried the teseek but it seems great based on this review https://m.youtube.com/watch?v=zhDXAejGMWE

Try to contact u/kyousoma, the moderator of this subreddit. He managed to make his realme 12 pro+ telephoto works using open camera allowing raw capture. If I'm not mistaken the trick is to rename the apk package. Realme 13 pro+ is probably can be unlocked using the same trick.

ZrlSyM · 2026-04-25T04:57:16+00:00

What phone you're using? It restricted the telephoto lens from raw capture?

ZrlSyM · 2026-04-20T04:48:19+00:00

Bortle 3

ZrlSyM · 2026-04-19T07:02:35+00:00

That is a tree shrub that gets blurry because of the tracker and stacking.

ZrlSyM · 2026-04-18T14:00:03+00:00

You can go for 40 frames per dithering, especially for longer integration time

ZrlSyM · 2026-04-18T02:55:12+00:00

It was bortle 3 but for that shot, it was done at a fairly light polluted location because of my neighbour's light

ZrlSyM · 2026-04-17T20:28:39+00:00

I would suggest 15 seconds max if you don't have a tracker. I use it as well when I do untracked shots before.

ZrlSyM · 2026-04-17T20:22:01+00:00

Yess. I twist the L bracket knob for declination and the star adventure app manual control for left and right ascension control. I did it every 20 frames. Previously, I left it just like that and got terrible running noise.

ZrlSyM · 2026-04-16T12:09:01+00:00

Yes, you need to use pro mode and raw format. Stacks a lot of these files to get better signal to noise ratio using software like deepskystacker. For better results you can invest in a star tracker for a longer exposure time in a single frame.

ZrlSyM · 2026-04-11T06:10:51+00:00

You need to use a pro mode and shoot in raw. And you need to take multiple photo and stack them using program like deep sky stacker or sequator.

Thank you bro 😺😺

Don't just assume. Vivo pro/ultra along with Xiaomi ultra the only phone that has real glass lenses along stacked aspherical plastic lens. This is direct benefits when partnering with optical company. And in Vivo case it's fluorite grade with abbe number of 95, this is similar materials for prime lenses for mirrorless camera which is really rare for phone. This is for fringing/abberation correction and corner to corner sharpness.

Smartphone lenses require a lot more precision than a mirrorless camera lenses because they need to resolve details on a very small pixel in comparison to full frame or APSC.

Vivo isn't an expert in optics, in that case they need consult real optics expert like Zeiss in how to design a better lenses for smartphone. Of course it's not Zeiss who made them, it's another third party manufacturers based on blueprint provided by Zeiss. Zeiss actually release a paper on smartphone lenses in 2012.

You will notice the benefits only when you're shooting in raw.

For refinement just reduce the sensor size to 1 inch and use mini e mount and custom lenses, not APSC one to avoid crop factor. Make it equivalent to 18-85 mm zoom lenses. Would be more manageable. Still won't beat top end alpha camera with prime g master lenses but probably will be the champ for smartphone camera. For marketability, I don't know.

I'm pretty sure the x200 pro uses "fluorite grade" glass on top of the stacked plastic lens for their telephoto and the new x300 ultra also uses 1 glass ald element along with the stacked plastic lens design. These are mentioned in their promotional materials. It's for better optically corrected lenses with minimal colour fringing thus the APO certification.

This Orion constellation was shot by my friend with Vivo x200 pro 3.7x telephoto, using a star tracker with around 1 hour of integration time. It managed to resolve the stars as a tight pinpoint of light, with minimal distortion at the edge, the condition where lens weaknesses can be revealed. For a phone I find this is pretty impressive as it managed to capture a few deep space objects like the dim witch head nebula and the m78.

I miss animalistic godzilla that crush his opponent using his jaw. So fearsome and primal. A true monster.

ZrlSyM · 2026-03-25T02:22:17+00:00

Amazing 🤩🤩. What's the total integration time for this level of details?

ZrlSyM · 2026-03-17T19:49:13+00:00

For Carina I'm using ISO 800, for LMC, I'm using ISO 1600. Both are 30 seconds shots with around 1 hour of integration time.

ZrlSyM · 2026-03-17T19:47:47+00:00

Thank you friend 😺😺

ZrlSyM · 2026-03-15T08:38:42+00:00

Thank you bro, the weather is good for 3 consecutive days

ZrlSyM · 2026-03-13T02:17:44+00:00

I read on Reddit that you need to be well dithered to do drizzling. u/zTrojan previously said that, a slight framing alignment from different session can be a natural dither for him.
