Update on the 2.0.0 release & the full manual

We are getting close to the 2.0.0 stable release and the full manual. The manual will soon become available on the website and also in PDF format. Both versions will be identical and once released, will start to follow the APP release cycle and thus will stay up-to-date to the latest APP version.

Once 2.0.0 is released, the price for APP will increase. Owner's license holders will not need to pay an upgrade fee to use 2.0.0, neither do Renter's license holders.

No easy way to ask this so I'll just tell how I gathered my image data....

I did 2 hours worth of Dual band HA/OII with an Optolong L-eXtreme Filter. Then 1 hour 'each'

using my single band OIII filter and my SII filter...Three different filters.

Now, when I processed it in APP, I selected the Split Channels method. Trying to segregate each color. then after running thru the HA, OIII and SII. I selected the Combine RGB tab. After running it all thru, then selecting the color sliders like I normally do, I ended up with a reddish image, no colors. 

Does APP distinguish the OIII and SII from my light frames and pull this out? When I loaded up all the frames, calibration frames, etc, I did it all together at the same time...

Was this correct, or am I doing this wrong? I've never tried to process an image before using three different filters. See Screen shot of image.

Thanks,

Rod

What algorithm did you choose in CombineRGB? I also wonder if this object has a lot of OIII/SII data..

@vincent-mod 

I used the HSO-1 Method, selected Add at the top next to where it says Normalize, just below the Add Channel Tab...It's getting better...This is the SHO Hubble-2, still needs post processing

NAN RGB SII SHO Hubble 2

 

Maybe I should use the SHO Hubble 1 or 2...

Ah there it is. 🙂 Yes, so the different presets will show you what channel data is being combined and how in the sliders below. You can always make your own mix, the ones you choose are just presets.

This one was strange in that it did not like the Luminance. I had all three channels down near '0' before the colors showed. It was looking like a bright ball of light before. I'll just keep tinkering with it. Thanks
