Keen to hear if anyone has used the Askar FMA180 Pro F/4.5 Sextuplet Apo Lens for astrophotography. I am in search for a lightweight to go on a tracker for wide field shots of bright objects, like Pleiades or Orion etc.
I am keen more on the quality and not whether it is possible, as I suspect the latter is already the case. I currently use a Sigma 105mm, but that beast is extremely heavy and I want something that can get me up closer and with the same great sharpness the Sigma offers.
Any thoughts or suggestions - or better alternatives - would be greatly appreciated
