The next clear opportunity suffered from poor transparency so my next attempt with the Tair 300mm wasn't expected to be very exciting. I went for the very large IC 1396 nebula in Cepheus which more than filled the field of the lens so perhaps more suited to the field of a 200mm. The lack of transparency resulted in the processing being pushed hard with only the brighter regions showing well including the well known Elephant's Trunk Nebula and Herschel's Garnet Star at the top. Details: Tair-3S 300mm@F5.6 . 12 x 8 minutes @ iso1600 with CLS in DSS, FIV, CS2 & XAT.
