Thanks Rich.
The Pentax K-5 is a good astro camera - dust it off!
Despite its age (I've had mine since 2012) the K-5 still holds up remarkably well, even against much newer and more fancied cameras when it comes to
long exposure noise.
See this long exposure test which lists a whole lot of cameras:

At 30 and 300 seconds the K-5 is ahead of such great cameras as the Nikon D850 and all of the Canons (as long as you don't go over ISO 3200 that is - the K-5 falls off a cliff above 3200 and gives you green banding everywhere - plenty of the newer cameras can realistically shoot at ISO 10000).
There's a lot more to an astro-camera than LE-noise however and taking good astro-photos can be about what you do with the equipment you have. Check the astrobin link in my sig - nearly all my photos were taken with a K-5 or astro-modded K-5iis.
