Luna: Schiller, Tycho, Plato etc.

Hi all

Here's 6 lunar images taken yesterday morning after my session with Jupiter. The seeing had deteriorated by that stage and the temperature continued to drop, and I had "waves" of bad seeing fluctuating and rolling across the image.

Not to mention, my tracking was horrendous in DEC and I had to constantly keep pressing "up" on the hand controller to keep the feature near the middle of the screen. As a consequence, alignment and stacking was a nightmare and I couldn't align on anything near the edge - resulting in some blurry parts of frame near the edge. Yes, I need to work on my EQ6 alignment

Each image is the result of 5 alignment points stacked in registax, 500 frames on each point (out of 1800 captured (1 minute each feature)). Schiller is a 2-image mosaic as it was too big for one FOV.

Resolution is 214 metres per pixel.

Schiller and Tycho are the best of the bunch, the others are fairly ordinary but it was nice to capture some Luna again.

1. Schiller
2. Tycho
3. Arzachel
4. Plato
5. Davy Crater Chain
6. Copernicus

Thanks for looking.

Very nicely done Mike. I like the slumped wall details in old copper knickers!

Cheers

Dennis

I had to think about that for a second there, Dennis

Well done, Mike.

Looks like you went on a good old tour of the moon there Mike!
yep, Schiller is great followed by Tycho in my books as well.

Great shots Mike, they look like you could step out and go for a walk.

Old Luna is always good value

Cheers

Thanks guys.

They were shot with the DMK through the green or red astronomik filter (i can't remember which

)

Hey Mike.

Why use a coloured filter if your image is going to be monochrome?

Do the coloured filters help with the sharpness of the image?

iceman (Mike) · #11 12-04-2007, 08:29 PM

Yes Matt, they block IR for a start, and by allowing through only certain wavelengths, you can "beat the seeing" and end up with a sharper image.

Red is good to use the majority of the time, and I've read that if the seeing is really good, then the green filter is even better.
