A star tracker designed with the primary considerations of low cost and high portability. If you have to carry your gear to a remote shooting location this is the tracker for you.
Not wanting to spend time fighting my photos I wanted a camera that was capable of usable one shot color images. In order to keep costs down this is a smaller, less expensive, version of the camera I use on my no-expense-spared EQ setup.
Sensor: Sony Back-illuminated 9mp 1" Color CMOS.
Quality Specs: 3.76 pixel size, 50ke well depth, 13 stops dynamic range, 80% peak QE
APO Triplet Refractor. Refractor telescopes are the most like camera lenses and so the easiest to use for those of us coming from a photography background, and have low comatic aberration. The APO Triplet part just means that your money is being spent on correcting chromatic aberrations.
Welcome to dedicated astro cameras; they're stupid. The ASI533 pretty much consists of a sensor and an air conditioner, that's it, no brains. You can use a laptop and freely available software (linked to at ZWO site) or you can buy one of these dedicated astro computers and control the camera over WiFi with an app on your cellphone. This Mini version is smaller and more light weight than the others.
This will make you the envy of all the other astrophotographers. Electronically controlled focusing that can be fully automated to recheck focus based on time passed and/or temperature change.
An overpriced red dot sight; except it includes everything needed to mount it securely to your telescope or the accessories mount. This makes aiming the telescope much easier.
You can never have enough stuff:
Dew Heater - by slightly heating your lens it keeps dew from forming and blurring your shot. I've forgotten to turn mine on before and actually had the lens frost over.
Portable Power Supply with 12v DC Port - something like this with a 12v DC port to power the ZWO ASIAir, which powers everything else.
Optolong L-eNhance 2" - Dual Narrowband Filter blocks all light except for Ha & OIII which are the primary colors of deep space objects.
