Recommended back focus to flattener for use with the GT81 telescope is 62.1mm

Precision machined aluminum and steel.  40 years experience making EQ mounts.  Unlike other companies, when Losmandy advertises a weight capacity that is the actual photographic weight capacity.  (If you buy an EQ mount from another company expect the recommended photographic capacity to be half the advertised capacity.)

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.

A field flattener works to correct distortion and focus issues around the edges of the image.  Don't even think about shooting full frame without one.  A Reducer trades focal length for speed (no I will not argue the technicalities of this point with you).

Not wanting to spend time fighting my photos I wanted a camera that was capable of usable one shot color images.  Pretty much a cooled version of the mirrorless I already owned.

Welcome to dedicated astro cameras; they're stupid.  The ASI2600 pretty much consists of a sensor, an air conditioner, and a dew heater, 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 Pro version also includes USB and 5v power ports for accessories. 

A mono uncooled astro camera, with the Mini version designed primarily for guiding.  It has a fast video rate so can be used as a planetary camera also.

She's a wee bonnie guiding scope with a really nice adjustable back focus system.

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.

It's a wheel that can hold up to 5 filters and change them electronically.  Pretty self-descriptive isn't it.  It's just that easy to use too.

Power Distribution Unit = PDU.  The ASIAIR has PDU capabilities built in but can't handle quite as much power as this, and this has a few more ports.  Coming with an external temperature/humidity sensor it figures out the dew point at your telescope and adjusts the dew heaters as necessary using the 2 dedicated dew heater ports.
