    Cool The Amazing Planets

    Last night, the stars came out ... and how!

    This is Venus ... and although it usually is a bright "body" in the celestial sky, last night it was roaring! I took an image of it, this morning, around 5AM ...

    @ f/2.8 - 1/500 sec - ISO-200 - Manual

    but, it was the settings that I took it with that I truly find amazing. I can assure you, I was not fighting for light. Kind of spooky, when you are not expecting it.

    Above, is the 100% crop of the same shot ... from a 200mm shot, nothing more. The brilliance was simply stunning. It should be so for the next several nights ... with a dimmer Saturn creeping in, directly above it, on September 4th.

    Yeah ... I miss that telescope idea. Decisions, decisions ...

    Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
    Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography.

    Question Get me a step-ladder, will ya?

    Yeah, I have to get closer to Venus ...

    "Hey, Venus oh, Venus ... make my wish come true!"

    Well, I got the Kenko Teleplus PRO 300 3x T/C (SONY-mount), today ... so I guess it's a start.

    Come on, the darn planet is 41.44 million kilometers from my sensor. Even that is going take some doing to shorten up.

    Actually, with the AF 200mm APO G HS strapped on ... it seems to deliver an acceptable shot ... @ 600mm f/5.6! I have to push the ISO to up the lighting, I suppose ... but still ... the lens-T/C combo is only about 8.5" long and exceptionally lightweight (36 oz total). That's a whole lot shorter and lighter than the TAMRON 200-500mm (43 oz) @ 200mm. I'll do some side-by-sides, later this week. It could be important in deciding what to pack.

    Anyway, I suggest you check out the eastern sky, early tomorrow morning ... and I think you will be impressed.

    Dot's all, folks!

    A 3x TC is 3 stops, so you're looking at 600mm F/8 with the 200mm APO G HS F/2.8.

    Without a telescope, stars and planets aren't worth it. And especially at F/8, there's no light coming in to get a decent exposure. You would need to track that sucker for a while....

    Might as well go wide and get a constellation.

    The A700 is indicating f/5.6 ... so I am not complaining. It autofocuses ... and that's alright by me. If is actually f/8 when it comes to actual optical performance ... but the camera thinks it is an f/5.6. It does the same thing on the A850 ... stating the lens is a 400mm f/5.6 ... a 2x T/C ... the the device acts as a 3x T/C. Hope that is helpful. It sure probably is confusing, but seeing is believing.

    Look, I was only kidding concerning any features. You guys are missing the point ... I popped a 1/500 f/2.8 ISO-200 exposure and got a bright image. Figure it out ... That's as bright or brighter than the moon! I certainly was not expecting any detail ... just luminescence.
