Question Venus - 22 Apr

Here's the best I could pull from 2047 frames.
Takahashi TOA 130/G-11
ToUcam Pro II and Schuler UVBRI Filter
K3CCDTools and PS CS2
Taken on 22 Apr 07

It's taken me this long to pull a decent rendition of our beloved second planet.
I believe there is some cloud definition there. What do you think?

Well done Scott, it really is a cow of an object to image. Sometimes, twilight or even daytime is better.

Very nice Scott. That's a lot of frames to stack. Imaging Venus really does require a different approach compared to other planets.

Did you do this before sunset, or after, and what was the planet's elevation in the sky at the time? How was seeing?

Great shot of Venus Scott. I am amazed that you were able to stack that many frames without the program crashing like it does on me!!

Well done!!!

All,

Thanks for the positive comments.

To answer Robert's question -- I started taking frames after the sun went below the horizon. That was the best seeing with Venus about 15 degrees above the horizon. Seeing got progressively worse over the next 6 AVI attempts of between 600-700 frames each.

And Brian, I don't ever seem to have issues with K3ccdTools no matter how many frames I stack. It's Registax that hates me and always crashes before I can finish the alignment sequence.

I'm gonna keep messin with the frames that I have in case I can pull a better one.

A little more fiddling with this image I tried for a more natural color balance.
