TEC - They now only do Fluorite triplets and start at 140mm F7.Ĥ. Takahashi - a close 2nd and they dominate in some areas like the FSQ106EDX for example is hard to beat.ģ. Only really available 2nd hand as they have a long wait list, like years.Ģ. AstroPhysics - fairly universally regarded as the absolute best and my experience as well. Unfortunately that means expensive high end scopes in my opinion. You mention you only want to buy one to last for a long time. Takahashi FS102, FS152, FSQ106N fluorite, FSQEDXiii (FPL53), TEC110 F5.6 fluorite oiled triplet, TEC180 F7 fluorite oiled triplet, AstroPhysics 140 F7.5 and reducer. There are lots these days so it can be a confusing area. I have quite a few high end refractors and recently I have begun becoming acquainted with the more modern offerings.
#Ts photoline 130mm review pro#
My mount will be the SkyWatcher EQ6R Pro with SynScan. I know the doublets are great and if you would like to educate me how a doublet is better than a tripplet then please let me know.
Im also really only intereted in the triplets too. Im primarily imaging DSO and i would like to make this purchase a 1 time purchase since i most definitely wont be able to drop this kind of cash on a telescope again.Īnyone with experience with anything between 100 and 132mm would be great to hear from you. Im hoping for some advice from people with experience with these focal lengths and brands. I also have limited experience with brands such as William Optics, Explore Scientific, Skywatcher etc.
