Hi all,

Seeing conditions this morning were the best we have had for some time on Lower Eyre Peninsula. Although still imaging through gaps in cloud and had to stop at 3:00 because of dew, I rated the seeing at 7/10.

This image was captured at 10 fps gain 40% gamma 50% saturation 100%. Stacked in Registax 3 and finished in Picture Publisher.
Used 2x barlow also for the first time.

Comments welcome.

Wow - that is a BIG image; I assume it was captured with the 14" of glass? You've got some nice detail there Lester, with the GRS just peeking around the limb too.

Well worth the effort given the conditions you describe. How are you focusing, as it looks a tad soft?

Cheers

Dennis

Thats a good one Lester, well done. It was just a matter of time before you got some semi-decent seeing. I may have a go at your image in pic. publisher if it's ok..

I was out there too & got 2 AVI's but a couple of hours earlier. Ol' joop was undulating bigtime on screen. It was a spur of the moment decision, no cooldown or anything which did not help.

You must be happy, thats your best yet.

Edit: Couldn't resist, had a play with your image. Split in astraimage, ME deconv. 7/1.4 Tweaked gamma etc in pic. publisher, resized.

Thanks Dennis and Asi for your replies,

Yes Dennis focus is a bit rough, from one side of focus to the other the planet moves one complete field of view, from one side to the other just out of vision.

Think I need to look into a micro focuser to do the final fine focus, if they are available to fit straight onto rear of Mead SCT 14".

Thanks Asi for touching up my shot, you can do that any time.

Now that's more like it, well done, white spots storms and GRS peeking round and great iage scale. CLoud/dew might be conspiring a little preventing you getting peak sharpness or perhaps a tadd off on collimation and or focus as Dennis suggests?

Anyway, great pic

Thanks Robert,

Yes need to some how fine tune the focus.

Here is another avi captured at 5 fps and still playing around with processing settings.

very nice, be keen to see more images produced through the 14"

Thanks Beren,

Still looking into fixing the focus/ image shift problem. Because I purchased the 14" SCT OTA only and not as a complete LX200 which includes the Meade #1209 Zero image-shift microfocuser.
