- ZWO OAG
Purchased to improve guiding...
...in urban skies. Coupled with a QHY 5L-II and ZWO OAG and fits well and first time out did seem to improve guiding. As always, prompt delivery and reasonable price from OPT.
This works perfectly
This product works perfectly for what I wanted it for - planetary and lunar in IR
It works somewhat on mars and Saturn but leaves it discolored. Woks great on the moon. Not had a chance to use on nebulas yet due to weather. Cant really see a lot of difference in turbulence.
Best for planets7
My view of Saturn and Jupiter was as if I never saw them before.
Astronomik ProPlanet 642 BP IR-Pass Filter
I've only had one night out with the ProPlanet 642 IR-pass filter but the results were excellent. I imaged the 3-day-old waxing crescent Moon on an evening with really bad seeing. While visually the Moon and planets were disappointing, I did capture a very clear image with Mare Crisium and craters Langrenus and Petavius showing details. Mind you I did take about 3000 frames and chose only 1, but at f/7 at 1/250 sec. (SV110 ED Doublet and ZWO ASI178 Mono camera, prime focus) the results were very satisfying, even with the sun was still above the horizon. I'm looking forward to imaging Mars during the July 2018 opposition using the C14. Thanks OPT!
Hard to find filter
Had a hard time finding the in-demand AK642 filter. Glad to see Opt had in stock - was in my hands within a few days, even coming form CA to OH. Also, not my first purchase from Opt, never disappointed.
