DMK Jupiter 3x From Broken Hill 4th RGB of 22

Hi All
This is the 4th of the 22 RGB's from last night. The seeing was very good to excellent. Later in the night it got so good, the detail visible in the raw feed to my laptop was excellent in the R and G channels and even not to bad in the B channel.

Am going out observing with my astronomy group tonight, out of town, but will have a big week of processing next week.

Regards
Trev

That's really nice, Trevor. I reckon some additional processing could do wonders on this one.

Could you post a version just after stacking each channel?

Hi Mike,

Have attached images of the R, G & B after stacking in RegiStax.

The quality of the seeing never really got worse than these early captures and many of the later ones are better.

I did this every 10 mins for 3 1/2 hrs.

Hope to finish stacking in RegiStax and combining in Astra Image tonight, then I will work on the animation next week.

If the animation is as good as I expect it to be, is there any way of uploading it, as obviously it will be more than 200 KB?

Also have redone the first two images of the sequence that show some detail on Ganymede.

Regards
Trev

Regards
Trevor

Hi Trevor. I'll have a go at these tomorrow, thanks.

As for uploading, check out the IIS FTP Service. Chuck me a PM!

How many frames did you stack with those, Trevor?

And how did you save them to upload? They look like they've been fairly heavily compressed already which will make them almost unusable.

Can you save them as TIF's or BMP's from Registax after stacking, and then upload them? Or maybe email them to me: mike@iceinspace.com.au

Hi Mike,
They are stacks of 500 of 1200 for each channel.
I save them as TIF files but posted JPGs as the TIF,s would have been over the upload limit.

I have just finished processing all 66 AVI,s and some of them are absolutely stunning. I will email the RGB files from the image you were inquiring about plus a set from about 2hrs later that show truly amazing detail in each channel.

Regards
Trev

Looks like pretty special data sets if that is just stacking alone. You did have a great evening.

Hi Trevor

Thanks for your email. Are you sure you saved the ones after stacking 500? It appears that there's very few frames stacked, as I can hardly apply any wavelets to them before they turn very grainy - something I usually see after the "create reference frame" step when only 50 frames are stacked.

What wavelets do you normally apply at this stage?

Hi Mike,

They are stacks of 500 frames.

By trial and error I have come up with a regime for the wavelets in RegiStax for my 3x images of Jupiter.
I have saved it and reload it for each stack then apply it.

Wavelet 1, 30.9 Wav 2, 15.2 Wav 3, 7.8 Wav 4, 3.8 Wav 5, 2.4 Wav 6, 1.7

This has already been applied to the stacks of 500 that I sent to you.

The folder that my work from 01/08/2008 resided in, currently stands at 23 GB.

I have now converted the 66 R, G, 7 B TIFF's into FIT's files in Astra Image and have thus far combined 10 RGB images. There is some amazing detail west of the GRS.

I will post a couple of these this afternoon.

Regards
Trev

ah - I wasn't aware the wavelets had already been applied. That explains it then.

Do you have any versions (the best of the lot?) without any wavelets applied?

Why are you converting into FITs? AstraImage works on TIF's just fine.

Hi Mike,

Will save a set of my best RGB's with no wavlets and email them to you.

When I load my TIF's into Astra Image and convert them to greyscale they are saved as FIT's files for recombining the R, G & B files.

This is all new to me, that is what Astra Image seems to want to do.

Are you saying that there is no need to convert each R, G & B to greyscale?

Regards
Trev

Hi Trev

Thanks, look forward to the email.

In AstraImage, load your TIFs, convert to greyscale - no worries.

Then do your ME or LR deconvolution, and then recombine the result of those into an RGB image. You don't need to save any intermediate files - just save the final RGB combined image as a TIF file, for taking into Photoshop for any final adjustments.
