Thank you David, they are 0.09" D'Addario. I used 0.08" strings before but I had to get the secondary holder out when I replaced my secondary mirror recently and so I decided to get new strings too and the shop didn't have any thinner than 0.09" (it's much easier to work with new ones when stringing the spider) I don't see any noticable difference in the diffraction pattern though.

Thanks very much Mike
I have been slowly improving my setup bit by bit, now I really only need a new primary mirror. Hopefully in the next couple of months!

How effective is the secy Dew fan? first impression is that it'll "blow" photons away!!, pun intended, but better than a secy heater solution.
Is that a single 5kg or 10kg counterweight? Are you able to balance the OTA, camera, finder with that single counterweight?

Thanks Alistair, yes I balance everything with a single 21 lb counterweight. The truss OTA is very lightweight despite its rather solid appearance
The dew fan is extremely effective. Without the fan my secondary will dew up rather easily, but only on one occasion did I get dew with the fan on. But that was in near 100% humidity and fog rolled in shortly after so not much hope anyway.
I have never heard of others using fans on a secondary though, don't know why?
