Up until 5-6 years ago this brand had a great market niche for lower end ED refractors in the USA. Then Svbony entered the market and impacted the AT cash cow for Astronomics, who by the way owns Astrotech. As a consequence it is most likely that AT profits margins have dropped significantly. Now those of you card-carrying CN Astrotech aficionados will take umbrage to this post but so be it. This is just one person's humble opinion. In order to protect the Astrotech brand, whenever new Svbony posts are made about their telescopes, in particular the refractors, some moderators/administrators and card-carrying CN Astrotech affectionados will undertake protective measures to dissuade members from considering the Svbony brand. Posts will be removed, new posts will promote AT scopes, other posts will try to change the subject. It is so good that this does not happen on Astronomy Connect. If you were in the USA, Svbony, Skywatcher or Explore Scientific and other refractors sold by Agena Astro are options you should consider. I have both an Astrotech 80ED and a Svbony SV503 80ED. I definitely prefer the latter.
