irandar Posted August 26, 2023 Posted August 26, 2023 HI folks, I have a set of files from Telescope Live and find that stacking of the HOS files in 3 groups fails because of alignment. I can stack the individual H, O and S files which works ok but message says a few in each group do not align. How can I proceed with each group? Maybe edit each group and at the end paste together as tiff files? Using APv1. Thanks for your advice. Quote
irandar Posted August 26, 2023 Author Posted August 26, 2023 Update: I find I can copy the 3 pixel groups and paste them together. Will try to proceed with the JR group composition HOS and stretching. Quote
irandar Posted August 26, 2023 Author Posted August 26, 2023 I renamed and used the HOS group but that does not work. I see misalignment. Quote
irandar Posted August 27, 2023 Author Posted August 27, 2023 Update: I contacted Telescope Live and got the answer that they have often heard that there are problems with Affinity Photo's stacking, while other software does work. That is really not what I wanted to hear. I have not tried different settings for the stacking. Maybe this would bring something. There are about 30 HSO FITS files in the set. Hoping I do not have to go to another software for stacking. Thanks and regards Quote
irandar Posted August 27, 2023 Author Posted August 27, 2023 Update: I have tried changing the stacking options. Apparently it is necessary to reload the files for this. But stacking failed again with the alignment message. Quote
Staff Lee D Posted August 30, 2023 Staff Posted August 30, 2023 @irandar Can you confirm you workflow to the point of receiving the alignment message and also provide me with a download link for your files via DM? If not, I can arrange for a DropBox link to be sent to you to upload the files to. Quote
irandar Posted August 30, 2023 Author Posted August 30, 2023 Hi @Lee D, The work flow was as follows: Select "New Astrophotography Stack", then adding the Light frames in groups, Group 1 Ha, Group 2 OIII, Group 3 SII, (all frames seemed to be ok) then chose Stack then came the alignment message after stacking. There are about 30 FITS. I tossed out the zip file and would be glad to have your Dropbox link. Thanks, Irving Quote
irandar Posted August 30, 2023 Author Posted August 30, 2023 Forgot to say that the filter type was correctly chosen for each of the 3 types. Quote
irandar Posted September 13, 2023 Author Posted September 13, 2023 Hi @Lee D Did I send you HOS files that I was having trouble with? It was a couple weeks ago. Thanks and regards, Irving Quote
Staff Lee D Posted September 13, 2023 Staff Posted September 13, 2023 @irandarThese are the folders that you uploaded. Quote
irandar Posted September 13, 2023 Author Posted September 13, 2023 Hi @Lee D Thanks. Were you going to check them out to see why they are not stacking? Regards, Irving Quote
Staff Lee D Posted September 13, 2023 Staff Posted September 13, 2023 I've got them to test the stacking process. Can you confirm what you have the Type set to for each file group and are you changing any other options? Quote
irandar Posted September 13, 2023 Author Posted September 13, 2023 @Lee D As I wrote earlier the work flow was to select "New Astrophotography Stack", then adding the Light frames in groups, Group 1 H-alpha, Group 2 OIII, Group 3 SII, (all frames seemed to be ok) then chose Stack then came the non-alignment message after stacking. No other options were changed. The Type was set to Light Frames for all but the File group numbers were changed for each and also the filters were changed for each. I have done this many times. Thanks Quote
irandar Posted September 19, 2023 Author Posted September 19, 2023 @Lee D Hi I guess there is no news yet about my stacking problem. In the meantime I have another question about Affinity Photo's astro ability. An Internet contact has sent me a large number of files he has taken of a nebula, SH2-124. He has gotten a very good result. He is a very advanced astro guy with good equipment. I am pasting all the info below and want to ask you Affinity folks whether AP can handle so many files, a total of 370 fits gathered over about 20h. Thanks for any guidance you can give. Best regards, Irving 40 Ha dark fits total 40 40 darkflats each for Ha, Sii and Oiii total 120 fits 40 flats each for Ha, Sii and Oiii, total 120 fits 30 lights each for Ha, Sii and Oiii, total 90 fits grand total 370 fits SH2-124 RA(α) 21h 38m 17s Dec(δ) 50° 19′ 48″ Bortle : 4 SHO - Total exposure time : 19.5 h Sii : 30 x 900 sec Ha : 24 x 900 sec Oiii : 24 x 900 sec Mount EQ6R Pro Celestron C8 EdgeHD / 0.7 Celestron field reducer Imaging camera ASI1600MM (G139 @ -10°C) Pegasus focus cube zero EAF Pegasus Falcon rotator ZWO Filter wheel Optolong LRGB - SHO (3nm) filters ZWO OAG (L) Guide camera ASI174 mini Guiding PHD2 Dark – Flat - DarkFlat Aquisition NINA Post-Processing : Pixinsight – Lightroom Quote
irandar Posted September 22, 2023 Author Posted September 22, 2023 @Lee D Hi, The stacking of the above SH2-124 files: 78 lights HSO and all darks and flats worked out fine. Took only 3min on my iMac. Still waiting for your verdict on the TL files that did not stack. Attached the result. Regards, Irving Quote
Staff Lee D Posted September 22, 2023 Staff Posted September 22, 2023 @irandar I've been testing but they also fail to align for me. I've asked another member of staff to take a look as they've done a lot of astrophotography to see if they can suggest why they aren't. Quote
irandar Posted September 22, 2023 Author Posted September 22, 2023 @Lee D It would be a shame if they could be stacked on another software but not on Affinity. Thanks for your help. Quote
irandar Posted September 24, 2023 Author Posted September 24, 2023 Hi @Lee D, Had a bit of trouble stacking again. These were files I got from a tutorial about Astro Pixel Processor. About 80 lights LRGB and maybe 80 calibration files. My iMac 2017 crashed twice during stacking and sent reports to Apple. The third time was a charm and all went well. Stacking took about 10min. Thought AP would like to know. Here is the edited result for NGC 292. Quote
irandar Posted October 3, 2023 Author Posted October 3, 2023 @Lee D Hi, Any word yet from your stacking experts regarding the Telescope Live files that I sent you? Thanks and regards, Irving Quote
irandar Posted November 8, 2023 Author Posted November 8, 2023 @Lee D You were going to ask your stacking experts. Any word yet from them? Thanks and regards, Irving Quote
