Vlaiv is right. He often is 🙂 Steve

These new AZ Go2 telescopes are essentially replacements for Sky-Watcher's earlier AZ-GOTO models (appears to be same but with integrated Wifi, no need for dongle, and no handset). As far as we know, the smaller AZ-GTi mount is is not due an update so will continue unaffected. HTH, Steve

Strictly speaking it is the AZ-Go2 WiFi Go-To Alt-Azimuth Mount that is new 🙂 Sky-Watcher AZ-Go2 WiFi telescopes The AZ-Go2 mount has integrated WiFi (creates it's own WiFi network) so can be controlled wirelessly using your Smartphone or Tablet, via the free SynScan App for iOS or Android. Stock should start arriving at our warehouse early next week.

James M. Spangler invented the first commercially successful vacuum cleaner and was awarded the patent. William H. Hoover was so impressed he purchased Spangler's company and patent. So, strictly speaking, we 'spangle' the carpet 😁 ... I'll get my coat. Steve

I understand ZWO's decision to include a proper cooler. The camera is designed for today's market. A market in which the majority of astronomers want a cooled camera. Will tomorrow's astronomers still want cooling? Perhaps not. But that is then and this is now. Steve

I see where you are coming from, modern sensors are less dependent on cooling, but demand for cooled cameras remains significantly higher than uncooled. HTH, Steve

Yes. Sorry. We have updated the product title 🙂

We have several in-house brands. StellaLyra telescopes are mirror-based (CC, RC, Newtonians & Dobsonians) so manufactured by Guan Sheng Optical (GSO). StellaMira telescopes are refractors so manufactured for us by Long Perng or United Optics. For SL and SM accessories and eyepieces we source from the same three manufacturers. (The StellaMira prism diagonal mentioned earlier in this discussion is manufactured by Long Perng). We are open and transparent regarding manufacturers. Here at SGL we credit the manufacturer whenever we introduce a SL or SM telescope. It is not a secret and we don't pretend to be an optical designer or telescope manufacturer 😇 We have good relations with all three manufacturers. They and we are delighted with progress. No objections of any kind 🤗 HTH, Steve

We do now 🙂 Celestron 90° Prism Diagonal HTH

I see what you mean now 🙂

The version without iPolar has it's own product page 🙂 iOptron HEM27 Hybrid Harmonic Drive Equatorial GoTo Mount HTH, Steve

The price has not been set so it was probably an error when we created the product page. This happens sometimes when we duplicate an existing product page then edit the duplicate to create a new one. Quicker and easier but prone to errors. Sorry ☺️ HTH, Steve
