ARs 2550 & 2551: Finally on Band!

[cshahar]

Hi Everyone:

I have been experimenting with different band widths, as I wasn't happy with the detail / contrast I was getting before, certainly not up to snuff for the Quantum filter I was using. Although high thin clouds were bothersome, and prevented me from experimenting fully, I was able to discern that center band was way to the blue wing on my unit. The difference was remarkable. This ran counter to what Daystar claimed was a well-calibrated unit. But the important thing is that I know center band is somewhere between 6561.8 - 6562.2. Here are two images at 6561.9 and 6562.0. There seemed to be very little difference between the two bands, notwithstanding the variability in seeing and transparency, although the 6562.0 has a slight edge.

Very nice results. You have definitely nailed the tuning there

great shots mate, the second one is more contrasty and may be a bit sharper,both cracking images.well done.  charl.

[laudropb]

Very nice images. Looks like you have solved your problem.

[Pete Presland]

Very nice looks excellent.

[cshahar]

Thanks everyone. I am quite happy with the results.

Cracking detail in those two Charles.

Lovely images Charles. Nice to see some action captured from terra firma.

Here is a sharpened and final version of the image.

Superb detail Charles, you can get really nice 3D effects on the edge when tuned just right, never seem to get long enough clear skies here to experiment.

Thanks Dave. I really do hope your weather improves. We had 2.5 months of almost straight clouds last summer so I can relate to what you are saying! The sun is exceptionally quiet today so at least you know you are not missing out on any major action...

[Stub Mandrel]

So contrary to what Daystar say, the 0.4A filters are fine for both surface details and proms?

[cshahar]

Yes, surprisingly, I can catch quite a bit of proms particularly if I bump up the exposure slightly, but even if I don't.

In fact, in post-processing I can extract proms galore. Its great to have both options...

Ooooh, very nice, Charles.

[paulastro]

Excellent Charles, superb detail.

[cshahar]

Thanks both. I appreciate the encouragement!
