Night photography tips

Dear Marco, first thing: I really do thank you for the whole post you had the effort to write.

Really, really, thank you.

I premise: I had previously some experience of night photography: I have a tripod and the three lenses I mentioned.

I asked how to get the best out of I could with these lenses as for now I would prefer not buying another lens as I'm going to leave for a central asia trip next week and I'm already carrying three lenses. Furthemore, buying the 22mm would be not using anymore the 11-22 and it would be a pitty for me

That's why I want to try some "settings already tested" for the lenses I have to get nice pictures

I've never thought of taking night sky photography with the 32mm indeed as I know, even though a fast lens, not suitable because of POV.

In the last trip I realized the beautiful 32mm hasn't IS..:D

This lens doesn't need Image Stabilization because of the wide f/1.4 aperture. Most super-bright lenses tend not to feature I.S. And Night photography of this nature demands that a Tripod be used. The EF-M 32mm f/1.4 is the fastest native lens available in the EF-M mount but it's also a more narrow lens, producing a less-than ideal field of view (FOV). So you can either use it to take a narrow shot of the Milky Way or you can tile several images together into a Mosaic with it.

The fact the 32mm hasn't IS has been misunderstood as I was refering the fact (untold) that the last trip I took most of the videos with the 32mm but came back home I realized the were shaking....because I didn't know the missing of IS.

A Mosaic of 4 images taken with the EF-M 32mm f/1.4 lens on the EOS M6.* A NiSi Night Filter was used for this photograph.

I use the function "merge" of Lightroom to merge various pictures but the result isn't nice most of the time (in the morning, indoor) so I think how I could get a nice result with night photography...

But it my worth a try: I saved your settings!

In particular - do you have any nice tutorial to learn some skill to take pictures similar to the second one with the lamp light beam?

Taking pictures with a flashlight in the scene as a prop is easy enough for anyone. You may find that you need to turn off the flashlight after a couple of seconds, even if your exposure is much longer. You can turn the flashlight on and off at any time during the duration of the exposure.

GREAT!

I tried with the 32mm but I couldn't stand so much as 20-30seconds (with ISO 400) without moving and at the end the beam burnt the picture...

The ideal exposure time for the EF-M 32mm lens is going to be under 15 seconds. You can take a longer exposure if you want, but the Earth is turning and this will cause the stars to produce trails. So instead of dots for stars, you'll seen lines forming. The brightness of your lens (ie widest aperture) and the focal length of your lens will determine how long your maximum exposure can be without the stars trailing. A few pictures down, I have shows the ideal settings for the four EF-M lenses that I have on hand. You can use the same for the same (or very similar) results. I used a Bortle 3 location (rural) for those shots.

This shows how much of the Galactic Core (the brightest part of the Milky Way) can be captured with the EF-M 32mm f/2 STM lens.

How much field of view your EF-M 11-22mm has compared to the EF-M 32mm lens.

Ideal settings with the EF-M lenses I had on hand. Shot in a Bortle 3 location.

Did you set this value in M-mode according to your "eye" or you used A-mode?

Do you think that over ISO 5000 the picture will start being noisy?

If you're interested in taking pictures like the ones you posted, the methods or techniques vary only slightly, depending on the lens used. The same camera settings

Just one more question: how can I disable the AF and set the focus to infinite with the 11-22 or 32mm?
Some lens have a specific leverage but EF-Ms don't (the 32mm has but I don't know what it serves..)
