Adam. Thank you for your explanation on such a “misinterpreted” subject. I have been taking picture exclusively with an OSC camera and have been thinking of starting Mono as soon as my budget allows. The doubt that I still have is what type of filters I should get. Reason tells me I should start with LRGB but, it appears that in many cases I would prefer to use Ha, OIII, SII. I would appreciate your opinion and advice on this. Thank you.
For most people..the brightness of the sky determines the answer. Under light pollution narrowband is the way to go. However, dark sky is always best... LRGB is still a bit "faster" since you get more light through the system under dark skies.
Very cool, Adam. I was lucky to have attended the conference the last year, and was disappointed that it was not going to continue. A lot of great content for everyone enjoy.
14:53 I asked ChatGPT if "MiB" means "Megabytes" in this context and this is what it said: No, “MiB” is not used to mean “megabytes.” “MiB” stands for “mebibyte,” which is a unit of digital information storage defined as 2²⁰ bytes, or 1,048,576 bytes. This is different from a “megabyte” (MB), which is typically defined as 10⁶ bytes, or 1,000,000 bytes. The distinction between “MiB” and “MB” is important in fields where precision is required, as they represent slightly different amounts of data. The use of “MiB” follows the binary system (based on powers of 2), while “MB” follows the decimal system (based on powers of 10).
Interesting. Thank you. In this particular case the distinction is not useful and there is no precision. The fact it shows us a number is not necessary. All we need to know is if there is information cached or not...not the size.
Thanks! You answered 2 questions I had! I can now combine 3 different exposure sets of M31 that I gave up on... that'll be around 40 hours of data instead of 12. Plus answered the question I came here for which is stacking east & west veil at the same time... I forgot to change the registration reference mode, simple fix! Thanks again :)
Excellent video Adam! I will be placing my order for the Fundamentals soon. I have put it off too long. It's time to understand what I am doing as opposed to sliding levers or changing values in the hope it looks better. I don't know if Fast Track is where to begin as I have been working in PI for a while. I know how to do things not why to do things. Any ideas where someone who has some experience should begin? Just FYI the repository link you have for the Image Blend Script didn't work for me. I copied it from the PI web site, and it worked fine. You might want to take a look.
Well.... Fundamentals includes FastTrack Training. So I would get Fundamentals and start at the beginning (FastTrack). If you know everything... then just keep going!
Thank you. I use and discover the diverse possibilities of the ImageScript more and more. You may want to consider a video(s) exploring the various functions of ImageBlend for us non Photoshop experts.
Aloha Adam thanks for the great video and all the work that goes into them ! I have not used Either of these processes yet but will play around with it for sure ! Having become a Member i can say it has been a master class in Image processing and well worth the investment!
I love Image blend and use it all the time! I have been using it to also put my stars back in but that is possibly not what it was intended for it seems
@@AdamBlock ok good lol. I usually try to dim the stars with Image blend as I have had a real tough time with all the Cygnus targets having a billion tiny stars in the images hiding the nebulae. Maybe I can boost the nebulae and not have to dim them so much
You could. There is an additional benefit for ScreenStars that I am not taking advantage here in this video- avoids is an issue where stars in strongly colored nebulosity take on the hue of that region. That is the reason in general. However, you need the original image with stars embedded in the nebula to take advantage of this math.
Hello sir, I was wondering if proper background extraction for narrowband is covered in this? I always doubt that if the data I have is true to what it should be. Clear skies!
Not In the beginner's/introductory content. I think you are referring to continuum subtracted results? If you just mean extraction of color in the specific case of OSC- this is covered in my masterclass. Is this answer good enough for you?
It's a very good piece of software to cheese it. But, no photoshop version? LOL, a money loss for the guy who made this, majority uses photoshop cause already work in other fields. I will never buy pixinsight, 300 more vat for that? Majority of people are not professionals, we do it cause is a hobby, and we will keep doing it. So, for me is a non sense. When your images already good, pixinsight or photoshop do the same, that's called diminishing returns.
I'm new at using Pixinsight and trying to use Image Blend, I have separated the stars from the nebula image. When adding the Nebula with out stars image to the base image it just shows a black preview, same with adding blend image the stars image. am I missing something? I check that all the settings on image blend are the same as the one on your video. Not sure how to proceed . tks
Hi Rick... no, the settings are not the same as my video. You are mixing Linear and non-linear images. How to proceed.... Buy access to my videos at AdamBlockStudios.com Given your name you would agree that is "Fair" isn't it?
A brilliant explanation just like all of Adam's content. For anyone who finds this useful, I would highly recommend purchasing his Fundamentals and/or Horizons courses.
Without a doubt, this is the best source for image processing (especially PixInsight, but the general principles are applicable to any software) tutorials. Well worth the membership fees. Adam is not only an expert, but he is a great teacher.
Yes... OSC with dual band filters are covered. Once the bands are extracted and you have Ha and OIII (plus even SII) then the workflow is the same as mono.
Adam's Fundamentals and Horizons are the best astrophotography 'equipment' purchases that you can possibly make. Not only is Adam Block the best astrophotography educator on RU-vid, he is the best educator of any subject that I have found on RU-vid. I come back to his content time and time again I appreciate that you learn how to approach problems and get a full understanding of how certain techniques work, not a sequence of buttons to press.
I'm embarrassed to admit how much I've been anticipating this lol. Is there a way to combine the mosaics code and the narrowband code down the line for Horizons? I would just get Horizons now but I'm broke from buying a new mount and all of your other videos lol.
That gets really hard! The combinatorial codes I need to manage will be significant. Comet Academy, Mosaics, NB Fasttrack and more... My preference is that people get ONE course and then Horizons. However you are right..I will need to prepare for the different versions of this. Let me think of how to handle this. I might have to limit this to two courses or something.
@@AdamBlock Oh yeah that's fair, that does get tricky. I feel like two is probably fair, and is where I would be at. I just got the mosaic one a couple of weeks ago and really want to jump on the narrowband now. I am also antsy though, might just bite the bullet and go full Horizons now lol we'll see.
@@_TriffiD_ Yeah..I get it. However this is a member site that manages multiple complex offerings (some subscription, some not). So you can really only have one card processor. My site uses Stripe- which is every bit as good as PayPal... maybe better. I am happy to create a PayPal invoice for any non-subscription offering. (it is the subscription bit with automatic payments that requires one processor and integration.)
@@AdamBlock Oh, I didn't know that. Of course I see that you have to decide what is best in your case. I just thought that credit cards are not overly common in some parts of the world. France an Germany have a coverage of about 50 to 60% I believe) I don't have one because I would use it once in 5 years. So I failed last year to get your "Fundamentals", just because I could not pay.
@@_TriffiD_ Well.. Stripe is actually number one over there... and my offer is still good.. you can get Fundamentals with PayPal if you want. Just let me know.
I love Adam Block's videos! Through taking his courses he builds the foundation for you to solve problems that you might encounter in astrophotography. If you think PixInsight is scary, don't be afraid when you have Adam as your guide!
I’m wondering how this darkframe method performs when you have a sensor with a lot of amp glow. Wouldn’t you end up with a lot of “hot pixels” in the part of the frame where the amp glow manifests itself?
Excellent question. The answer is apparently just fine. The developers worked on precisely this situation and are proud of their results. I suspect the multi-scale treatment of the image does something to avoid amp glow being an issue. However, they have not shown the exact method/math.
Thanks for the update. I notice that when using the automatic cosmetic correction the file extension is simply c and not c-cc. This could be a bit confusing to some. Not a huge issue, but something to of which to be aware.
Interesting! I will need to look into this. I suspect the idea is that CC is now considered an option of the "calibration' process... It is now in ImageCalibration. I think this is the reason why. I will need to communicate this.
So, how would you apply this to Seestar S50 processing? I've just been using auto-detect and leaving Hot Sigma at the default of 3. I know it's only a Seestar, but I'm using it as my first platform to learn post processing. Thanks.
I am guessing you are getting calibrated frames out of his system. So this means yes, the auto-detect method is for you. If you get raw darks and lights- then you can use the new method.
