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.
I am very new at all this, and am on a steep learning curve, so apologies if this is a dumb question.... I recently shot a subject with LRGB, Ha, Oiii and Sii filters. Is there any point in using all of these (the subject was a spiral galaxy, not a nebula) in APP, or should I just use the LRGB for it?
Like we mention more often, there are no dumb questions. 🙂 Maybe you learned that in school, we really don't care and are happy to answer any question you may have.
For galaxies it won't make a lot of difference indeed. Maybe if you can see some Ha regions in the galaxy, like in M31, it does help to add some Ha signal to the mix. I would advice to just try it basically, you can save the split frames (into R, G and B) and then combine them in the CombineRGB tool with 50% R and 50% Ha for instance. If that really doesn't add anything or even reduces the result, just go with the RGB.
