I heard a lot that dobsonian telescopes aren't good at all for taking images at DSOs,

but if I'll use my phone, with pretty decent camera, will I able just to send some decent pictures to my friends, or is that impossible?

And what about just planets?

 

Thanks!

It all depends on what your standards are for images. Will you get a hubble photo you can frame? No. You might get picture of a little faint blob of nebulosity on M42 or the core of m31 that is a nice conversation starter at parties but as far as DSO imaging you won't get far. Obviously the moon and planets are fun and easier to do with a phone.

You can and will get an image/photo.

The catch as ever is the expectations. They ALWAYS exceed the equipment and the person.

 

Planets are liely to be a problem, not many at the present and they are small, very small.

Actually, it's much easier to photograph the classic naked-eye planets than DSOs using a smart phone and a Dob. That's because the planets are typically at least 100 times brighter than even the brightest DSOs, which pretty much eliminates any issues with inadequate exposure times. But yes, the images will appear very small. That's the way they look to your eyes, too.

 

It is quite easy to photograph the Moon using just about any smart phone/telescope combo, and the results can be shockingly good.

You aren't paying attention. While not, as you say, Hubble quality, this example is far from a "little faint blob of nebulosity":

Images on phones is still Astrophotography, and discussion of astrophotography is not allowed here.
