Originally posted by PenPusher ...From reading most of the the astro sections it seems to me that you attach a C mount adapter and a 1.25" tube to the Q and insert this into the telescopes empty focusing mount which does not seem right to me as I would have thought you would attach it to one of the focusing eyepieces...
Either technique can work. The 1st highlighted portion, using the telescope as a big lens, is called "prime focus". The 2nd highlighted portion is called "eyepiece projection". Eyepiece projection can give more magnification by swapping eyepieces or adding extension tubes between the eyepiece and camera. That extra magnification also results in a darker image.
For astro usage, eyepiece projection works well on the moon and planets. Planets are tiny and need magnification, and they are still bright enough despite the darkened image. Deep sky objects (galaxies, nebula) use prime focus because they are already so dim that you need lots of exposure time.
The Orion Starblast scopes you are looking at are more for visual use than astrophotography. You should be able to get good photos of the moon, maybe decent photos of planets, and possibly photos of brighter deep sky objects but you won't be able to take very long exposures due to limited tracking accuracy. Astrophotography mounts are generally bulkier GEM (German Equatorial Mount) designs.
Note that astrophotography is rewarding but also a source of frustration many nights. On any given night it can feel like your gear, the weather, or your skills are fighting you. If you think LBA can be bad, what until you experience TBA (Telescope Buying Addiction). I recommend
