Rupes Cauchy and Lunar Domes

[Zac Pujic]

Here is Rima Cauchy, Rupes Cauchy and a couple of well known lunar domes.

31 cm Newtonian at f/28. SkyNyx 2.1M. Wratten 25A filter.
Frames stacked using 41 MAP points with Registax 4beta.

Nice image, Zac. Great to see some images from some good seeing.

How does R4 MAP processing handle avi's where the tracking isn't very accurate?

Hi Zac

Another fine image of an interesting piece of Lunar real estate. The dome with the "hole" in the top looks interesting.

Cheers

One question Zac, are you taking these moon shots in RGB, or just mono with the skynyx?

[iceman (Mike)]

Nevermind I just read the "Wratten 25A filter", so I assume mono + red.

[Zac Pujic]

My camera is a mono so the images are taken as mono + red. Also, the monochrome SkyNyx camera saves the files as greyscale data. Some cameras like the ToUcam can be toggled to b/w but they still save the files as RGB which is wasteful of disk space.

Registax 4b handles poor tracking as well as it did before. If it is better, it is certainly not greatly noticeable. It currently still has some problems but Cor is working hard to eliminate them. He's releasing new builds every 2-3 days. He's set a tentative date and its not toooo far off. The MAP function is not difficult to use and we're working to to make the user interface streamlined at the moment. Occasionally a file will, after a 50-MAP point run, give an area which obviously has not been stacked well. It can be repaired, but that pales into comparison with the manual process of MAP which I think some members here are painfully familiar with.

thanks for looking!
