A very nice and methodical demonstration of WBPP. A fter using BPP with an OSC uncooled camera for several years, this shows how to make astro images with my new ASI183MM cooled pro camera, in WBPP seeing as the older BPP version is soon to become archived by the Pixinsight team and taken off the updated newer downloadable versions of PI. Very good video thanks.
Superb video Linda, easy to follow, no jumping around, and the file management was much easier to understand seeing it rather than reading about it. Im going to try and emulate that. Im mostly after WBPP for the weighting of my photos such that slightly fuzzier photos dont dominate the final stack and this does that. I have far more data on imaging nights since im moving to a three telescope system same focal lengths, all the more important to keep the files organized. Nice work, will be looking for your other vids since this is the first tutorial ive watched of yours!
Thanks, Abe! I'm amazed there are people out there running three rigs at a time! But, this process should work for you. If you run a different filter on each telescope then you can put them all in one session for that night since the flats won't conflict. Let me know how it goes for you!
Glad you found it useful! However, since that was done, WBPP has evolved to directly support multisession data. See Adam Block's Definitive Guide to WBPP 2.0 for the details on that or my video on Manual Multisession Processing that talks about how much simpler it is to do in WBPP in the second half.
Hello Linda ... this is a great tutorial. Thank you for the effort you put into it. Everything is clear to me so far, but I don't understand how and where I integrate my flat darks🙈 Could you explain that to me again?
Thanks! Review the video from about three minutes in to about seven minutes in. I go over how the master darks and master flat darks are created. Remember, that from WBPP's point of view a flat dark is just a regular dark. It doesn't distinguish them so they are alll grouped together in the "dark" tab.
@@LindasAstronomyAdventures I thank you for your answer😊 I watched the video two more times and finally understood it🙈 I still have one question ... I take photos with a one shot color camera with RGGB. Do I have to debay every night or can I only do that at the end if I integrate all nights?
Glad it makes sense! You should be able to save all your debayering until the end. Since you only debayer right before registration and you don't do that until you have all your frames then you can save it until then if you want. No harm either way.
Hi Linda, when Calibrating the light subs using flats and a master darkframe, do you ever have any difficulty? Out of a recent 10 sessions on the Heart Nebula, all with their own flats, I found two sessions produced clipped light subs after calibration. All that is visible are the stars, with a black background with no image of the nebula, and that is stretched. If you have anything to suggest of a way round it happening I would be all ears. Thanks Dave
Not directly... let's start with the basics....are you sure all your nights of data were taken at the same gain/offset/temperature? Using a dark from a higher offset on a light with a lower offset might cause something like that. Also, double check to make sure you used the right set of darks each night. If you haven't seen Adam Block's Definitive Guide to WBPP 2.0, take a look at thiat. It's now possible to do multisession processing all in one go now so it might be worth trying that to see what happens.
Thanks very much. The sessions in question I processed separately. The darks (I'm pretty sure) and lights matched. ie exposure 300s gain 135 and the temp. -10c. Using Sharpcap pro as the capture program there's no offset choice with ZWO cameras ( ASI183mm pro cooled in this case) I've resorted to using the separate Calibration and Integration tools in PI. If I increase the output pedestal value to 200 they calib. ok though there's some evidence of ampglow afterwards. I'll watch Adam's wbpp videos. Best Dave
Thanks for the tips Linda! Your files are way more organized than mine. Calibrate now and integrate all later should really help with a better final image with more total and accurate data.
Hi Linda - another easy to follow tutorial. Thanks very much. I'm still using APP to do multi-session calibration & intergration as it's really easy to use and prompts the user about which session and filter data files to load (lights and calibration data). Your video however makes it much easier to follow the steps in PI though which is neat! I'm about to ask what may be a really dumb question - will this same proccess work where session exposure times are different between filters and even within the same filter? I'm also assuming it won't work where the binning is different between various sessions?! Cheers!
Thanks, Damien! I've only used APP a small amount. It does a great job but even with the recent updates runs much more slowly than PI. You can mix data with different exposures. If the exposure tolerance value is larger than the difference between the exposures they will get integrated together. Let's say you have 120 sec and 150 sec red subs. If your exposure tolerance is 60 seconds then those will get treated as one group and WBPP will integrate them together. The 150 sec will probably get weighted more heavily in the integration but it does work.
Hi Linda, no doubt you will have received the latest email from the Pixinsight team regarding the update to WBPP, namely WBPP 2.0? Have you had time to have a look at it yet? I'm interested to know your thoughts on it and if it will significantly change the way WBPP works before downloading and installing the new version if you don't mind me asking at this early stage of things. Bfn Dave
I've seen the email fro the PI team but haven't had a chance to even update it yet so you are ahead of me! I do see that Adam Block has put out some new videos about it. Having seen Adam's other videos, I'm sure they are excellent so I'd start there. I'm looking forward into digging into this myself!
@@LindasAstronomyAdventures Thanks Linda, I haven't installed the update yet either. I'll check and see if Adam Block has dipped his toes in the water yet. :-)
Hi Linda, I've had a good look through your video, and find it very informative thanks. A burning question from the end of the video, where the Master ha, o3 and s2 are found in the 'processed' directory, so if you could say how these three master file are combined to make one master image comprising of all three registered and aligned together? Do you use the separate Star Alignment and Integration tool to line them up and stack them ready for the final post processing or do you put them back into WBPP and Run it again without any calibrated frames at all? If you could say how, it would save me a lot of hunting around for the answer. Thanks Dave
@@LindasAstronomyAdventures Thanks Linda, of course they've already been aligned! Sorry to be so dum and not realise. Is the 'channel combination' in the script or someplace else? I'll check and see if its in the processes list. Mitch in one of his videos may have covered this a couple of years ago using Channel Extraction Linfit and Channel combination to separate RGB components, balance them and recombine. Sorry thats the extent of my knowledge.

IwBPP has already aligned them. I usually just use the channel combination process to put them together.

No worries...Channel Combination is a process, not a script. It's under the process menu and in the Channel Management submenu.
Thanks, good post
Glad you enjoyed it!
