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.

Can you advise what the standard option I should select when loading images taken on my DLSR with an HA filter. DO I choose the RGB option when I load my lights or the HA option. TIA

@gilgm Hi Mark. You need to choose RGB because the images taken with your DSLR are color images. APP will then debayer the images for you. If you are interested in a mono Ha image only then you can extract the R channel from the resulting RGB integration result. You can do this in APP of using other software.

Thanks Wouter. So for my HA filter I have taken Darks , Flats , Bias . Once I’ve integrated the lights I want to add the final HA shot to my RGb shots - same camera focal length etc . So is it just a question of loading the 2 final calibrated shots and integrating these . Thanks .

So is it just a question of loading the 2 final calibrated shots and integrating these .

Be aware that, if you want to do this in APP, you will need to split the two RGB results into their color channels.

To do so you can load the two integration results as lights into APP and then go to tab 2, select "split channels" and then click "save (calibrated) light frames". This will give you 6 files (one R, one G and one B image for each integration result) and you can delete the G and B files of the Ha image. Then you can go to tab 9 (Tools) and select "combine RGB". There you can select the "HaRGB 1" or "HaRGB 2" formula and then load the four frames. Just make sure that, when you load the R frame of the Ha image, you mark it as Ha. If you switch from either "HaRGB 1" or "HaRGB 2" to the other then don't forget to click the "new formula" button otherwise you won't see a difference.

Hi this is frustrating . I took a 4 pane mosaic with my clip Ha filter on my canon 600 Dlsr  . 20 lights per pane, plus flats , flat darks and bias. I calibrated ok. Set parameters to create a mosaic. All steps ‘seem’ to work but the final integrated frame is just black even at maximum stretch. Individual light frames can be viewed ok as can master calibration frames. I must be doing something wrong. On integration it’s using 85gb HD for processing- which I have 120gb free. 

Any ideas ?

Set parameters to create a mosaic.

What parameters did you set exactly?

@gilgm For mosaics setting the mode to advanced in tab 5 is essential. Also first try without changing the defaults in tab 6. If that goes well, we can start working with those settings.

@wvreeven

meant to say that halfway through there was a meridian flip so nearly half of each pane will be  flipped .

@gilgm That doesn’t matter since the whole image train flips so the images will be oriented the same.

Hi AM still having problems registering a 4 panel mosaic. 2 will register , 2 will not. Have integrated and stretched and processed with  LP correction and saved as TIFFs.

Co-ordintaes used via Telescpious and copied into plan Mode on Asiairpro. All 4 panes executed and Integrated ok with Flats, Darks , Bias and Master Dark Flat.

Using as Modded Canon 600D 

Tab 3 increased Analyse Star Count 

Tab 4. Start - 7 , Scale stop 12. Flip descriptors - yes. Dynamic distortion Yes. Same Camera Optics - No

Tab 5 Set to Advanced 

Tab 6 - 1st Degree LNC . Iterations -3. Enable MBB - 25% (Overlap on panes is 20%). Set scale to 0.3 - just to test.

It eventually finished with no output file - just a black screen.

Very frustrating as with the FL scope of 780mm - I need to use Mosaics, but just can't get it to work. Checked the final Panes against Telscopious and look the same ?

Are you using the files from stretched TIFF's? I'd advice to start with the raw data, make that into the panels, save them as fits (unstretched) and then make the mosaic. When the mosaic is created, only then I'd save it as TIFF and do other processing if needed.

I’ve used:

1. Non stretched Fits for each panel.

2. Stretched Fits for each panel.

As above but saved as Tiffs . Tried to mosaic for all 4 with no success.

I can have a closer look if you want? You can upload like 10 lights per panel and the calibration files to our server:

Go to https://upload.astropixelprocessor.com and for the username and password, use: upload

Create a directory named “gilgm-mosaicIssue” and upload in there. Thank you!
