    Thanks, squeege! You should try a variable polarizer; it works wonders!

    Yes! Yes! Yes! Experiment is the key. I live by your mantra. Being a composer/musician keeps me in a creative place and I try to transfer that energy to my astronomy pursuits as well. What ever it takes to get the final result.

    Break rules, make rules and then break them, too, lol!

    Good on EarthSky!!

    If they don't don't bite - they're idiots! :p And in-depth article written on top! Universe Today might be interested in writing-up an article too.

    Fingers & Toes...

    I think you've got the Kick-Ass Venus Photo Award.

    I hear Reggie has been awarded the Kick-Ass Venus Photo Award for capturing Venusian cloud detail.

    I'd say he certainly earned it. This was the sort of event that belongs in the text-books in the near future.

    I had another Venus/Jupiter session with the ST80 last night. I initially caught Venus at about 21:00 (British Summer Time). I tried a few filters and magnifications.

    Screenshot 2018-06-06 at 13.22.04.png

    I started with a Bresser single polariser in the diagonal and a Baader single polariser in the eyepiece. The 5x GSO Barlow was used throughout the session. I tried 18mm BCO, 15mm GSO Plossl, 14mm Bresser 'Super Plossl', 13mm Celestron Plossl and 12.5mm Fujiyama orthoscopic eyepieces. These gave 111x, 133x, 143x, 154x and 160x respectively.

    Screenshot 2018-06-06 at 13.23.32.png

    I could definitely see cloud detail with the polariser pair. The detail seemed easier to see between 133x and 154x. I later tried a Wratten #15, #21 and 23A. The #15 showed the detail I could see with the polarisers but not quite so well I thought. The #21 Orange was fairly successful, but the #21 Light Red was probably the closest to using the polarisers. From what I've been reading, being able to discern Venusian cloud detail could possibly be how well your own eye perceives UV light. Most UV is filtered out by the eyeball itself apparently, but some may reach the blue cones in the retina. These are the cones most sensitive to UV, and it can supposedly vary considerably between individuals. I have a mild form of blue-green colour blindness. I've seen cloud detail on a twilight Venus without any filters in the past, and it could just be that I'm sensitive to UV slightly.

    LOL

    BTW, now I'm inspired to try imaging Venus for more than just phases. I'll report on my efforts.

    Thought I'd join you for a day, Reggie. Not to worry - I'll swap back afterwards! :D

    ps - I'm letting an idea I have set into concrete...

    Let me bounce this idea off you first? Here goes:

    Mak has the software-program to produce these silly medals, yes? How's about we propose that members here who do something, ANYthing another member finds amazing and/or exemplary - the member can either run-off one of these things - or ask anyone with the software to run off said medal (with what was great on it) and send them a link to download the software to do such. The idea? Everyone ends up with a silly, gold medal!

    Needs a bit off polish, but that's what I've been kicking 'round. Ideas? Suggestions? Medications? :p

    Make it an anti-elitist elist award! :D:D

    YIPPIE!

    You only have to Google pictures of medals, screenshot it, then open it in something like Paint.NET. It's not rocket science lol.

    Ratz!! That's not good. A simple stand-alone software-program would be better. But I'll see what I can find over the weekend then. I'm not an expert on this sort of 'stuff.'

    Thanks, Mak.
