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.

Hello. I am trying to combine images taken with an Askar D1 and D2. My results are dreadful. Any tips for the stacking?

Background: I am fairly new to APP; been using it for a couple of years, maybe 15 times. I use an ASI2600MC Pro, a ZWO EFW with the Askar D1 (OIII & Ha) and then the D2 (S-II & OIII), 180sec exposures, 30 frames of D1 then 30 with D2 looping until Astronomical Dawn. The OTA is an Askar SQA55 with ZWO EAF, guided by an ASI174MM-MINI and SvBony 30/120mm guidescope. The Askar doesn't have a set backfocus requirement, but I run at 56mm. I used NINA Smart Exposure. Star shapes great, Tilt is acceptable. Most of this doesn't matter to the stacking workload, but someone always asks.

 

Thanks for the help,

Tyler

@monsonmjmgmail-com Hello, I am using a very similar setup, Askar D1/D2, ASI2600MC Air, Askar V telescope and I am 55-56mm of back focus.  I am not entirely sure how your images are coming out but this is my basic workflow for APP (most tabs are default).  Under 0) Raw-Fits, Pattern is RGGB, select Ha-Oiii Color for algorithm, and check Force Bayer/X-trans.  Under 1) Load, check the box for multi-channel/filter process (optionally multi-session if over multiple nights).  I keep my D1/D2 lights in separate folders and add master calibration frames to each folder.  Then select D1 lights, assign it to a filter (I name it D1), repeat for D2, ensure calibration frames are added to each filter if not already auto-detected.  3), 4), and 5) can basically be run as default (or tweaked based on your preferences).  Finally under 6) Integrate - I typically integrate "per channel and all" and then under multi session options I "integrate all."  This will give you a D1 master, D2 master and combined D1/D2 master.  You can also extract the Ha, Sii, and Oiii, channels in APP or PI to do a SHO workflow.  I have had very good results with this filter and workflow.

Ok, I still have problems. The stacked fits looks pretty good in APP, but when I take it to Seti Astro for my first post processing it "shows massive stacking artifacts" according to the Seti developer. Not too sure how to share the fits file, but the jpeg is attached. 

Thoughts?

@monsonmjmgmail-com Under #6 INTEGRATE and Mode are you using Full or Reference?  Reference should minimize stacking artifacts.  Even with the stacking artifacts in the picture you provided, they are easy to crop out (see my attachment of your pic).  You can crop them after it is integrated under tab TOOLS - Batch Crop. I always crop out a little of the perimeter so the gradient removal does not think it is part of the picture.
