Questions about BiggSky blind deconvolution

Hi David,

I just found out about this program and it gave me a pretty good result on Saturn from a 2 min .ser file. I have a couple of questions regarding this program. First I’m fairly new to planetary imaging, so some of my questions may be coming from an abundance of ignorance.

1: What happens when the 30 day trial runs out? Will it stop working, or will we get a new version/license?

2: Is it better to use the original .ser file or should I run it through PIPP and use the one of those files (.AVI or .SER)?

3: Is this used in addition to or in place of WinJupos?

4: What’s the best length of video to use with this program?

5: How can I maximize the results?

1. This should really be asked to the creators, don't you think?

2. It should be indifferent as the program automatically selects the best frames to stack.

3. This has NOTHING to do with WinJupos in any way, shape or form. WinJupos is mainly used by the public at large to de-rotate images for stacking RGB planetary images (or sequence thereof) taken from the Earth (or LEO). So it is in addition or propaedeutic to WinJupos.

4. That has nothing to do with the program but rather depends the planet you are taking images of and the resolution of your telescope/camera combo.

5. What is "maximize"?

Hi Craig,

As the creator of BiggSky, I’m happy to answer your questions:

1) While in beta testing mode, I am automatically extending demo licenses for all users, and will give at least a 30 day extension once the official first release and pricing is finalized.

2) It’s best to use the original SER/AVI file. If there is a particular feature in PIPP that is useful, let me know and I can advise. FYI you can define and ROI and check Crop, and have just that area tracked and stacked.

3) You can use in conjunction with WinJuPos if you want to generate Stack/Decon processed frames from a long imaging sequence in BiggSky, then derotate in WinJuPos and combine to create a noise reduced result.

4) There are different recommendations depending to the target and number of frames. 1-3 mins is typical. There are Stacking options for ‘MaxClipTimeSec’ and ‘MultiTimePoint’.

5) The first is to collect good data! In the app I suggest using the Auto Frames for % to Stack, which might be more than typical, but the reduced noise helps the Decon process.

There is an experimental feature under Decon to reduce Chromatic Aberration. Check Expert, then set PlanetRGBCorr=1.

For Saturn you can try White Balance by setting an ROI over the rings (see WB tab).

Davis answered your questions very nicely. I just wanted to add that I have used it with finished stacked single frames. I stacked in AstroSurface and then took the result into BiggSky. The high frequency information was then blended with the original image to keep the tones balanced. Here’s a Lunar mosaic using the process:

So far, BiggSky is better then anything else I’ve used for sharpening lunar/planetary imaging

Thanks for the response.

1: I was addressing this to the creator as I’ve seen he posts in this foum. Hence the salutaion of David.

2: The reason I asked is that PIPP has the ability to center the object/crop the original video to that area when creating an AVI. I was simply wondering which way provides the best results. David answered my questions.

3: Thanks for teaching me a new word. My intention was to determine if Biggsky does derotation as well as deconvolution.

4: but if the program is optimized for shorter videos say two minutes or under or longer videos two minutes plus, it tells me how long to shoot to get the best results.

5: To get the best results most efficiently.

Thank you for the detailed response. As I’ve got 38 sers of Saturn ranging from 2 to 7 minutes from last night to process I’ll take a few stabs at them.

Something tells me I have a long way to go.

That’s a seriously impressinve shot. Can you explain what you meant by “The high frequency information was then blended with the original image”?

I’m fairly new to this planetary stuff having been more of a Deepsky imaging guy.

You can load all 38 SER’s by using Open Images, then selecting the files.

Then click DoItAll, select desired Datasets, and it will auto Stack and Decon using the default settings.

It will take a while but is fully automated. Maybe start with 5-10 of the smaller files.

Make sure the latest v0.4.15 is installed: https://biggsky.com/download/

I brought the original and sharpened image into Affinity Photo. Took the sharpened image and split it into high and low frequency components. Dumped the low frequency part and blended the high frequency data into the original using the soft light blending option.
