A competition should be about skill, but then again, choice of equipment is part of that skill. As the skill component includes guiding, polar alignment, perhaps fixed pier initial setup, GRAS images are not in the spirit of the competition as these important and technically demanding aspects have not been the exclusive work of the entrant. Perhaps a weighting system could be in place to allow the less cashed up entrants to be able to compete with the Tak / SBIG brigade. This would test Greg's skill at weighting!
Perhaps, extra or different categories could be in place on the basis of rig cost eg under 5 K rig, 5-10 K up to house mortgage cost rig. This will reward the resourcsefull for their skill of setting up on the cheap as well as technical and aesthetic skill ie apples competing against apples. Oh for the good old days of 35mm photography competitions when it was application of some pretty basic technical/ equipment skills combined with a large dash of aesthetic /compositional skill.
