Oval BA, Friday 22nd June

[Kal (Andrew)]

This was my first real outing with the Toucam after moving on from my trusty old LPI. After processing the data I noticed that I had images the Oval BA feature

well done Kal, you have done very well, oval BA

Good start, Kal!

Feel free to share your capture settings and processing steps and maybe we can offer something in the way of improvements for next time? (seeing excluded obviousyl )

Very nice Kal - great results for your first real outing.

Cheers

Dennis

For the capture it was F/25 on my 10" LX200R. Toucam settings were 10fps @ 1/25s exposure, I used K3CCD to capture with the luminence? bar on the left at around 220.

For processing I used the start of your planetary imaging guide, using virtualdub to split the avi's into bitmaps, and then using ppmcentre to crop/rank/centre the frames. From theer I went into registax but I needed to use different wavelet settings, much more harsher than in your article to get a noticable improvement. I didn't do the RGBsplit/deconvolution steps in your guide for this image, I did try it with the same data from this run but maybe because I pushed wavelets harder in registax the results seemed to be worse.

I am a bit worried about collimation of my scope. I have the latest 'R' version of the scope and there are issues where I I can't get concentric circles inside and outside of focus. It is a known issue that I have read about on cloudynights, but until now I have never really noticed it with my viewing/imaging results. I am a bit worried that I can never get great results now because I may have a scope with defective optics

Here is another pic from the same run. I doubled the size in ppmcentre to process this one then reduced it to it's original size in photoshop later.

...Come to think of it, I can't honestly say I used wavelets on the pic from the original post. I mucked around trying several things and that could have been from one process I did where I used zero waveletts and alot of unsharp mask in photoshop. The colours certainly look dofferent to this pic which I definately used wavelets (+ double the image size to start with)

I think that's a better version, nice one Kal.
