I had a chance last night to try out the Ethos on my Tak SKY-90 which has a focal length of 500mm, this equates to approximately 38X. The viewing was about 9/10, very steady and cool. As I was observing undercover on my top deck it was only possible to view north so the obvious choices were Orion, Saturn and M44. M42 looked spectacular as expected in the Ethos and even at this low power, the trapezium was very sharp and clear. The field of view appears to be a little under 3 degrees. Orion's belt i.e. Mintaka, Alnilam and Alnitak is about 2 3/4 degrees and the EP would just encompass them. M44 (Beehive cluster) from memory is around 1 1/2 degrees and it is certainly great at this power as well. I used the TV 2.5X Powermate to look at Saturn and no loss of quality was noted. The planet was sharp and crisp and in such a large field simply looked stunning.

This eyepiece looks like a keeper, I have no trouble with blackout, kidney beaning or anything untowards. The Dioptrx is just brilliant to use and does what it claims, at least for me.

I have attached a couple of pics showing its huge size in comparison to the SKY-90. The scope has no trouble in coping with the weight and focuses perfectly with or without the Powermate. I still have to try it out on the TOA-130 which has exactly twice the focal length of the SKY-90 (1000mm). This equates to 77X which should be pretty useful for most objects.

Cheers,
