DSLR astro photography

Canon Rebel 300D was used for astro photography by many 10-15 years ago.
Some took out the IR filter or even installed cooling for the chip.
I heard, 6 mega pixel of the 300D is plenty pixels for photographing the sky!
Rebel XT DSLR can even do dark frame and subtrack after the photo was taken
Did any thing changed?
Are there better DSLR's now to do the same?

Almost every DSLR is better now. The sensor technology as improved
considerably. In particular, newer sensors have much greater dynamic
range and much lower thermal and readout noise. Those things are
critical to the quality of astroimages.

I have a Canon T5, very simple thing for astro photography don't have , like mirror lock up or bulb setting.
I think, the longest exposure it has is 30 sec.
Bummer!
T6 is the same!
Don't have the remote control, so maybe that has it?

There are also programs that can control DSLRs through their USB
connections. Some still work with old cameras, and can overcome the
typical 30-second maximum exposure. And yeah, some remote controls do
so by using the camera's bulb mode. If you're interested, check if you
can make a remote control. Especially with the older cameras, they
were often nothing more than a cable with a couple of switches on the
end. I made one for my 300D.

I still have the seocond hand remote for my gone 300D , but don't quit work with my T5.
It don't do mirror lock up, only shutter release on the T5!
I may thinker with it if I have time!

Just figured it out, in the T5, in the menu , adjusting the shutter speed beyond 30 sec, next is the BULB setting, in that mode mirror can be locked up with my wired remote.
Have to play with it more!

If you really want to try some interesting stuff, check out Magic
Lantern (https://www.magiclantern.fm/) This is new code that overlays
the existing Canon software, and hugely expands the functionality.
There is a version for the T5. I used it with my 7D for the 2017 solar
eclipse, giving me a built in sequencer that cycled rapidly through a
series of different exposures. It runs directly on the memory card,
and doesn't replace the existing firmware, so it's very safe. You're
not going to brick your camera playing around with it.

Yeah, but if you check the downloads page you'll see that the T5
version has passed all its tests. It may not be on the officially
supported list yet, but the code is there and almost certainly works
without serious problems.
