My First images of Jupiter RGB

Nice one Mullins.
I'd second Carl's sentiment there and say the first step
in getting the best image is a perfectly collimated and cooled scope.
Great work on the processing.
How many FPS can you capture with that camera using that scope?

Carl,
that second image is really very good.
Are these your first attempts a Jupiter?
or is it with the new RGB set up?

Don't know about the actual FPS it is capable of recording but I think the drop down box shows 30.
I just press record and it keeps grabbing them as fast as it can.

I am so impatient but you are right, I need to check the collimation before I do anything.
As soon as I get a chance I want to start observing before the clouds come!
I did check it indoors today and it looked OK but I don't know how reliable the daylight check is.

I wanted to try with my 2x Barlow too the other night but didn't get time.
As you see from my post the number of pixels actually hit by the image of Jupiter is very small.
Maybe with the Barlow I can use more of the pixels and get more detail.

When you mention cooling, do you mean just allowing it to cool to ambient temp. outside?
Would that be sufficient?

Carl, do you also use Registax?
If so, is there any chance you explain how you do the align stage briefly?
There are quite a few settings and I don't know how to ensure it is selecting the best frames.

Hi Mullins,
Have a read through this www.astronomie.be/Registax/RegiStax4UserManual_Revision1.pdf . When the seeing is steady there is no need to use the optimizer. After you Align the image Press Limit now see where the options are on the top, click show stackgraph. On the stackgraph you will see one red line witch is the quality and a green witch is the alignment difference. Bring the line down to cut off any spikes. Then move the slider across to adjust the quality cut off point. Now PRESS stack, Once stacking is complete press Wavelet button adjust image to your liking Then press the DO ALL button.save image and head to PhotoShop.

Hope this helps

Also if It's going to be clear out leave your OTA outside to cool to ambient temperature.
