Venus

Same set-up as Feb 11th. The phase has shrunk. I had some false colour, that shouldn't happen with a Mak but a bit of processing got rid of it and showed the phase properly.

Do you use plane polarising filters? For visual I find they seriously reduce glare on Venus. I don't do AP but they're supposedly good for imaging Venus, sometimes revealing cloud detail.

I suggested this to someone on another forum and he tried it and had this (link below) photo published.

Great idea, thanks. With a DSLR, I'm not sure whether I can fit mine but I have used one with my Meade Electronic Eyepiece and have used one visually. It was a quick session before dinner and I couldn't be too long as I should have been helping in the kitchen!

 

With a DSLR, I can control the exposure time.

 

When I first started, I used sunglasses to see Venus and Jupiter.

You're welcome. I originally used a pair of single polarised filters. I'd put one in the diagonal and one in the eyepiece. All I had to do was rotate the eyepiece to alter the transmission. This isn't so useful with a diagonal helical focuser. A couple of years ago I did a series of observations of Venus setting in twilight. With the paired polarisers I actually managed to see cloud detail. I told Reggie this and he used some Meade variable polarising device which achieved more or less the same thing. Except he managed to photograph it.

Sunglasses could work too lol.
