Keith Parker Posted June 6 Share Posted June 6 I have downloaded the NGC7635 bundle and processed passed the master HSO registration point and both OIII and SII have some major either gradient or background issues. I was just wondering if anyone else has come across this issue? Any suggestions on how to correct these issues? Thank you, KAP OIII_registered.xisf SII_registered.xisf Link to comment Share on other sites More sharing options...
Scotty Bishop Posted June 22 Share Posted June 22 Hi Keith, Go get the raw uncalibrated frames and use those with the raw bias, flats, and darks for those frames. Don't use the master calibration frames. You can get the uncalibrated light frames here: https://app.telescope.live/archive/my?showCalibratedImages=false&telescopeIds=61&targetName=7635 Go to the calibration frames after that and get your matching ones. The darks need to be 120s each and from as close to the same time as the lights were shot. The flats also need to be as close as you can get to when the lights were shot. The bias doesn't matter so get them all. https://app.telescope.live/archive/calibration?searchRadius=15&imageTypes=2,3,4&filters=(HSO),Halpha,SII,OIII&telescopeIds=61 You will also need to make sure you have your stuff in list view and set to 100 because 100 is the maximum you can download at a time using this. The cause of this is that there was some kind of calibration error in the calibrated light so you need to do it like you would with raw and uncalibrated files. Doing that has gotten me some good results from the SPA-2-CMOS stuff. Here are a couple examples https://www.astrobin.com/iucyav/ https://www.astrobin.com/aj6rrz/ Link to comment Share on other sites More sharing options...

Keith Parker Posted June 23 Author Share Posted June 23 Thanks Scotty. I really appreciate the assistance. I will download the files and get started on the processing. 1 Link to comment Share on other sites More sharing options...

ERNESTO GUIDO Posted June 23 Share Posted June 23 Hi Keith, Raw frames are compressed and PI is unable to read it. So you need to convert it before using the raw frames in PI. For example you can open the raw frames with free software SIRIL and then save it. After that PI will be able to read it. Otherwise you can follow the info shared in this post below: In particular there is a tool developed by @Jarmo Ruuth , you'll find all the info in the post above. Clear Skies, Ernesto Link to comment Share on other sites More sharing options...
Keith Parker Posted June 23 Author Share Posted June 23 Is this the same for the Darks and Bias, PI will not load them as well? And thanks again for the continuing support. Keith Link to comment Share on other sites More sharing options...

Scotty Bishop Posted June 23 Share Posted June 23 Give these master calibration frames a shot. Link to comment Share on other sites More sharing options...

Keith Parker Posted June 23 Author Share Posted June 23 Well, I finally figured out how to convert the raw files as well as the flats, darks and bias in Siril and am now running WBPP. Crossing my fingers here. Thanks again. Link to comment Share on other sites More sharing options...
Ken Abremski Posted July 15 Share Posted July 15 Hi Scotty, I followed your suggestions and used the uncalibrated raw files and the raw calibration frames with WBPP in PixInsight. Resulting masters and final image turned out well. Posted it to the gallery yesterday. Thanks, Ken 2 Link to comment Share on other sites More sharing options...
