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.
Hi,
first time using APP to calibrate and register images so I'm pretty pleased with the final image considering it was a 85% moon and gives me hope for the future 🙂
Stock Canon 5D4 on a WO Zenithstar 61 refractor with flattener and IDAS-D2 filter. The rig was mounted on a Skyguider Pro guided with a ZWO ASI120mm camera and 30mm f/4 guidescope. Really pleased with the 61 refractor with flattener on a full frame camera, next to no vignetting which is easily dealt with using flats
40 x 4 minutes subs and 20 darks/flats and 50 bias frames. Integrated in APP, processed in PI and tweaked in PS
Nicely done and glad you like APP! The background seems a little strange though, like if there is some blue and reddish coming through which might be noise, maybe a bit too high of a stretch?
But, great result!

It has been stretched more than I would like and I've played with Starnet++ to remove the stars, work on the background and then recombine them. Not my best work but good practise lol

This is a 'clean' version of the above image showing the field of view of the WOZ61 with full frame DSLR. I've cropped 100 pixels off all the borders to remove dithering artifacts. I'm really pleased with the corner stars produced by the Flat61A flattener

Indeed, looks like you've got a good flattener distance etc.
Vincent is right on - I'd not do that starnet removal thing. (at least not unless called for) the background was a mess. I cleaned it up some but I can only do so much with a final .jpg. Still I think this looks better. No worries, just go back to the data and don't do the star removal thing.Â
That's the cool thing. If I'm not happy with how mine turned out I can start new with the same data and be shocked at how good the 2nd try looks. Give it a whirl.
OH YEAH I didn't see clean version before I replied above. There ya go.

I agree the StarNet module in PixInsight is very aggressive but it does a very good job of creating a starmask for star reduction and background processing. I just used it badly for the first time 🙂
I shot the North American/Pelican nebula on Sunday evening which I'll post later where I also used the StarNet module but purely for star masking.
