Windy Saturn May 22nd

[Space Cowboy]

Despite the wind i got a reasonable image or 2 after having some hardware issues with the cameras losing contact with my netbook not sure if this was a driver or cable issue but need to do some tests. Anyhow after 45 mins of frustration got some avis using colour and IR.

This was first light with my new 3x tv barlow and 6" primary fan (cheapo laptop usb fan).

Below are a colour and colour/IR image using both QHY cams. Transparency was excellent making 50fps possible with 100% gain.

The ir image gets my vote again Stuart,nice work!

Very nice I'm amazed you managed to get anything if the wind is anywhere near as bad as it's been here for the last 24 hours or so.

Thanks Simon. Not much in it really, in fact I reckon the colour shot has more globe detail but the IR always produces better rings. The colour image was a 3 min avi when seeing was probably the best of the night and just a few mins later when I took the IR seeing had fallen off somewhat.

My plan was to take a colour avi followed by IR and another colour then combine the 2 colour stacks in winjup to produce a colour image with the same capture time as the IR (to prevent derotation artifacts) and split into RGB channels to then add the IR as the luminance but the resulting image is very noisy which is puzzling. So at the moment I'm sticking with the 50/50 IR/Colour combo (shown above).

Here is a 1.5x drizzle version of the above colour shot (85% scale) :

Thanks James yes I would not have bothered had I not been keen to try out the new gear.

Here is an IR shot from earlier in the evening.

Very nice images! Also liking the IR image.

Saturn is my current mission at the moment. Haven't tried with a 3x barlow so will give that a try.

Very nice images especially considering the conditions and your hardware problems. I assume they were captured on the 250 dob? I love the fact that you can get the northern storm with a relatively small aperture.

Oh for a clear sky!

Thanks Baggin!

Cheers Bryan yes taken with the Dob. Weather looking better for weekend so fingers crossed for some clear sky and calmer air!

Very nice images indeed. Like the way IR improves matter. Sky quality was so dreadful here I did not get to image at all. I am itching to get my ASI130 working on Saturn, but will have to wait.

Thanks Michael.

Repro'd the Colour & Colour/IR images using Drizzle then 75% scale this time stacking more frames (7000 colour & 6000 IR) combined in winjupos.
