Well, it wasn't raining last night - finally. There were even some breaks in the clouds (!!) so I set up. Got a few breaks in clouds in the mid evening but not really enough for some calm observing and comparing. Clear sky at 5am this morning - so I could finally have a look at M42 with and without the borrowed DGM Optics NPB filter. (plenty moonlight in the sky, but the view with the filter convinced me that I won't be sorry for ordering one.)
Back to the 30mm Ultrawide. I tried it in a bit of a rush. I'm comparing to the GSO 26mm and 40mm Kellners. I also tried the trick of screwing in the GSO 2" barlow lens.
I guess I have to say of first impressions - no "Groan", but "Hmmmm....." I'll get back to you after I get a more relaxed early evening's viewing in good conditions - hopefully this coming weekend.
