UPDATE FROM MABULA

I have had a very rough 2 months unfortunately health wise. I was struck 3x in a row with bacterial infections. The second infection occurred  after a routine hospital checkup and I became very sick. I had to rest and take a lot of antibiotics. Once I was recovering and restarting work 1 month ago, I again became sick. The infection was not yet gone, so even more antibiotics and rest was needed. Needless to say, it took a lot of my energy and I needed a lot of rest.

 

Finally, the infection is really gone and my energy is coming back step-by-step now and I have started work again. I am terribly sorry to have kept you waiting for support. I will address all outstanding questions and e-mails step-by step and will be on the forum daily from today.

 

APP 2.0.0-beta47 will come soon as well, a lot of work was already completed before I became very ill, so the release is also nearly ready for you. Beta47 will be much faster actually. Many workflows will be more than 2x faster, mosaics can even be 10x faster than before because registration really received a major boost... all compared to beta46.  Before I release it, I will make sure that everything is working properly and then I will release it.

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. 
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.

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.
