Description

This one was not planned. I was testing out sensor distances on my Samyang 135 with ASI2600MC piggybacking on my dual RASA8 rig, while aiming the RASAs at the Elephant's trunk (see the previously posted image). I had not realized that the squid was so nearby. If I had known I may have made an effort of framing this image better, but at least I did not accidentally decapitate the squid. To the 17 x 10 min of Samyang data I have added ca 50% RASA8 data to the Elephant's Trunk and 30% to the Squid. All with IDAS NBZ filters.
