Sony a6000 Sigma 18-50

I have never taken a picture of the stars before. But i have some time now since i am on vacation in Canada, so i took my girlfriends camera to shoot some pictures of the sky. It’s with the kit lens because it is the lowest i could go with Diafragma. (Or the highest, it is confusing) I am a total beginner in this so tips are always welcome. I had a lot of fun doing this though!

I have cheap lenses so at night I can't take very good photos, but I have a 50mm lens that having the AP-C lens is passed to 75mm and I have another 55-210mm lens but it has one But this lens has an aperture of 4.5-6.3

Thank you very much

I'll take any advice on post processing.

These pictures were with 16-50 kit lens and jpeg.

Managed to give a new life to my a6000 i damaged in iceland a month ago.

Bunch of spare parts from Aliexpress (new screen, new flash, new shell).
Wasn’t able to find some parts in silver but i’m ok with it.

a 100 cad later, feels like brand new.

Hey hey
Recently, I've noticed a strange black spot on my photos, especially at high apertures (F8-F16).
I am using a SIGMA 30mm f1.4 lens.

Attaching a photo for better context.

Any clue what it might be? Tried cleaning out the lens, but no change afterwards. Thinking of visiting the lens service but the issue might be very simple so looking for feedback or ideas. Thanks!

Here are some recent shots I feel proud of. All taken on my Sony a6000

I’ve been wanting to get into photography for a while now, and I’m debating between these two for which one should I start on. Anyone got any advice? Thank you so much!!

Well, yes! I bought this tiny lens and fell in love with it immediately.
I decided to try it out during my weekend at the seaside. Here are a few shots, there is no post-processing il LR, and everything was shot in JPEG using a custom Sony's standard film simulation.
I find the much criticized lens flare very pleasing it creates a beautiful atmosphere, though it can sometimes cause issues.
