Hello. There are a nice mix of humble, yet pleasing pictures, and very impressive pictures here.
So I would like to try astrophotography, and I'm planning to get an astrotracer O-GPS1 module.
Then, to get better deep red sensitivity, I would like to get a dedicated camera for the task, which would have its anti-IR filter removed and replaced by a more transparent one.
This modification would make the camera unsuitable for regular daylight use. So I would not inflict the treatment to my limited edition Pentax K5.
As the modification, which would be made by a professional, costs quite a bit of money, I'm considering one of those entry-level Pentax'es that have an aperture control block failure, those can be get for cheap second hand.
These partly faulty camera can only be used on manual mode with a lens having an aperture ring, but for an astrophotography use, this is not a problem.
Does this seems a pertinent idea to you ?
Which camera should I aim preferably ?
A 16 Mpixels K-30 / K-50 ? Or a slightly more modern K-S1 with 20 Mpixels ?
The K-30 / K-50 can function with AA / HR6 nickel-hydride batteries, a nice feature that K-S1 does not have.
