I would include
Vixen GP2 Photo Guider Warning for beginners: I would also say that these setups are not typical starter setups. I'd guess most of the people interested in these mounts have either used or own a bigger Equatorial Mount or telescope and want a downsized, simple setup to compliment what they have.
It is something that will fit in a suitcase or a backpack ,aircraft-cabin friendly or if check-in not much excess baggage charges, runs on a couple of D-cell batteries, and can be set up and ready to go in a couple of minutes.
To me, it sounds ideal for traveling to dark sky sites while on vacation or balik kampung for some quick imaging. It could be fun.
So it is to have as little equipment as possible sort of "Achieving More with Less". Most likely using a DSLR with camera lense or small telescope.
Thus it is not suited for visual use.
To do astrophotography saya terbaca primary goal is to have a mount with Periodic Error less than the sampling rate per pixel preferably unguided for less equipment.
Here is a
Calculator for DSLR Astrophotography which calculates the arcsec/pixel capability for various DSLR's with different lenses.
If you compare the arcsec/pixel capability of the camera/lense combo to the arcsec tracking capability of the mount it's possible to get an idea of how long an exposure you can take with each lense before star trailing becomes an issue.
For detailed instructions and concept, see article posted on
AstroPhotography Tonight Based on the above saya terbeli yang ni
