Thank you, I’m very happy to see you liked this video :)

Thank you, I’m glad you enjoyed the video! Great question! After using Astro Image Primer, use a linked stretch. The channels will be balanced and a linked stretch will be ideal :)

Thank you and you’re welcome! The narrowband filters mode does a decent job, but it’s more meant for true narrowband such as mono. The issue with OSC is the dual, tri or quad band filters with the Bayer matrix. Some of the information that SPCC uses gets filtered out which can hurt the results. With that said, SPCC can get a very close and good result, but more so sets the stage for NB to RGB stars to give a truly amazing result.

Thank you, I’m glad you liked the video :)

Thank you! I hope you are doing well :)

Thank you and I’m very happy to see this video helped! These are awesome questions :) Auto crop does a good job with cropping, however, I would always double check just in case to make sure the edges are clean. If the edges are clean, you’re good to go. BlurXterminator doesn’t really do much with the nebula as long as the stars are in the image, but if you run it on a starless image, the results are outstanding, however, you need a correct PSF value input into BlurXterminator for this to work correctly. You can extract a luminance from your image and then run the luminance through Scripts > Image Analysis > FWHM Eccentricity to get the FWHM measurement and use that number to input into the PSF diameter of BlurXterminator prior to running in the starless image. Another alternative to get the FWHM number would be to select your image in my Star Console script and not select any options and click Measure FWHM. It’ll do what I described above automatically for you. I am actually developing a script to automate this. For the last question, I do have a link on my website if you feel comfortable inclined to do so :) Thank you for your support! hiddenlight-photography.com/about-me-and-donations-1

Thank you and you are very welcome! Please let me know if you ever need anything or have any requests :)

Thank you! That’s exactly why I love PixInsight lol. The possibilities are virtually endless! Keep doing too much and see what it does. Tweak it and see if you can make it work and you’d be surprised how much you can learn and implement into your workflow. I find myself going too far all the time just to see what things do and how they affect the data :) Also, thank you, I am so happy the channel is growing like it is and all of the amazing people I’ve met along the way! :)

I came here to ask the same question. I thought the purpose of SPCC was to get accurate star colors. Running the NBtoRGB script seems to nullify that SPCC action.

This is a very intriguing question and I love it! The quick answer is no and I will try to explain in the simplest way possible. It’s important to understand in order to get true RGB stars, you need to image them in RGB. Using narrowband data, or dual narrowband in the case of this video, you can only “mimic” RGB stars. In the case of Seti Astro’s NB to RGB Stars script, you get a very accurate result that looks absolutely stunning! So why do I use SPCC prior and not just use NB to RGB stars? This is where it gets complicated. Different filters paired with different sensors give a lot of variables. The main issue comes from OSC and the Bayer matrix associated with it. With that said, some OSC data I get good results with the script and OSC dual narrowband data. Others, such as IC1805 demonstrated in the video, I am still left with mostly blue stars like you see in the initial star separation. Some of them get colors, but 98% stay blue. SPCC gets a close result when running. It actually get a very close result, but you can still tell there’s something just not quite right. This is due to the dual narrowband filters and the OSC matrix. SPCC works off of comparisons, PSF Aland flux data. The information that dual narrowband filters tend to reduce or eliminate. Now, when you set the stage with SPCC and then run NB to RGB stars you get that result you’re after. If you compare SPCC alone next to SPCC followed by NB to RGB stars, you then realize what SPCC is missing. The NB to RGB has the oranges, yellows pale blues etc. SPCC compensates a bit too much and the colors, even though they’re close, just seem a bit too much. I hope this makes. I think this could make a good video and if you’re open to it, I love to credit both of for the video :)

Hi Tony. Thanks for taking the time for a comprehensive answer. This is a complicated hobby and you have done a good job explaining your workflow rationale. Sure you can credit for a follow-up video.

You are very welcome! Great eye on that :) The background neutralization is on by default and, as you mentioned, there is no background and I haven’t found any issues by leaving it on. I didn’t touch base on it for simplification purposes as trying to remember more items can lead to confusion and frustration with some who are learning. As far as background neutralization goes, I’m not huge on it, but will be coming out with a video going over it as the series advances. I hope this helps :)

Thank you! Are you just getting into the hobby or looking to upgrade equipment?

@ just starting.

Thank you and I’m excited to hear my explanations were helpful :) I remember when I first heard the phrase “chasing the seeing” it took me a minute to grasp what was meant and I’m glad to hear my explanation of it was clear :)

That’s actually a very intuitive way of doing it :) Do you save each project as a new project or do you just update the project you’re working on and use one project save file? I’m very happy my explanations work, that is one thing I try to be very conscious of :)

@Hidden.Light.Photography I just open the one saved project each time I open PI and use it as a starting template of processes that I use regularly. I will update and save over it if I add any new processes.

Great question! What you want to do is add a second target just like you added the first target. Set your looping conditions for the first target so it finishes when you want it to such as time, altitude etc and then set your looping conditions for the second target so it finishes when you want it to. This will cause the first target to end according to the looping conditions and then move on to the next target. Once the looping conditions for the second target finish, the sequence will move on the end sequence. I hope this helps and if you would like me to review your sequence with you, email me your .json file to Tony@HiddenLight-Photography.com I hope this helps :)

​@@Hidden.Light.PhotographyThanks for the reply Tony, you're making this hobby so much easier for me I really appreciate it. I was wondering if you was going to start a discord. Once I'm home I'll email you a screenshot.

Thank you! It can definitely be a bit scary the first time, but once you do it once it’s not too bad. I guess it’s kind of like jumping off of the high five for the first time haha. I seriously applaud you for self learning this, that is truly AWESOME!

Yes, I agree.

That is very exciting!! I love Starizona, they are so friendly and knowledgeable :) What camera and scope do you have?

I’m very happy to hear this! Yes, I know what you mean haha. Is this your first rotator?

Yep. Issues I'm in the process of resolving are whether I'm going to be able to use the rotator with my standard ZWO setup as I have a mono setup use an EFW and OAG which means I'm at the full 55mm back focus. With ASKAR's design for my main scopes, the FRA400 and PHQ107, that's fine to add the rotator, but if I want to use it with reducers I'll have to look at swapping out the OAG and managing the 55mm back focus - something for another day. I did swap out the original ASI2600 tilt plate adaptor to the M68 version which allowed me to place the rotator as close to the scope as possible which allows room for the OAG bulk and helical focuser thumb screw tightener (which rotate to establish focus for the OAG) else they be vulnerable for collision with the Rotator's body during rotation. It would be a close call whether a M54 tilt plate could be used - but not tested. I still haven't tested under stars, but all appears to be working perfectly. It did however require some rethinking/evaluation of cabling and power supply. I'm a new ZWO AM5N owner and was hoping to make use of the off-saddle USB and power connectors. The distances between those plugs and end-points make cables short and prone to rotational "stress" which I alleviated by not using the saddle connectors - but then reverts to the well-known cable management issues. Also, the Pegasus 2 requires a powered port, which required reevaluation of power and USB cabling between mount, EAF, EFW, rotator, imaging camera, and guide camera vs. the available computer ports, and their data, speed, and power capacities. For anyone looking at a Rotator (regardless of brand), there's a lot to consider - but notwithstanding I haven't had first-light yet, I bought the Pegasus V2 well-informed and have no doubt it will perform exactly as expected.

Thank you, I am happy you are enjoying it! Have you captured any new targets lately?

@@Hidden.Light.Photography I have. Below is a link to my gallery on Telescopius

Thank you and you are very welcome! Guiding can be very fun to learn and knowing the adjustments and how to read what’s going on helps a lot with making the most of guiding and adjusting to different scenarios :)

Thank you, I’m very happy to hear this! Also, welcome to the channel and please let me know any questions or requests you have :) Clear Skies!

Thank you and it was my pleasure! I’m glad this helped :) are you currently working on a project that could benefit from HDR?

@Hidden.Light.Photography Yes, I am, sir. The Orion Nebula. I'm very new to PI, and I'm learning as much as I can about it. It's people like you that make it so much easier to learn and understand the functions of the program.

Let’s see if we can figure this out. Would you mind emailing me a screenshot of the script window set up right before executing the script and the console output? Tony@HiddenLight-Photography.com

Thank you and very good point! We definitely wouldn’t want that to happen :)

Thank you and you are very welcome! I’m glad this will be of good use :)

That is a very fun fact, thank you for that! :)

I’m very happy this helped! Please let me know if there’s anything I can ever assist with or if you have requests for content :)

Thank you and you are very welcome! :)

Awesome, that’s a gorgeous scope!! I’ve been meaning to get this out for awhile haha and very happy to hear it’s already going to be useful :)

I have a new CarbonStar RC6 and I think I have it collimated using a Chersire for the Secondary lens and a laser collimator for the focuser to Primary. Would love your take on doing a RC.

Oh yea lol 🤣 i definitely did that 🤦‍♂️ At least we got to do a demo of the Blemish Blaster script and I still have the masters to reprocess with the planetary nebula intact :)

I’m very happy to hear this helped! If you’re interested, I have an entire series going over NINA. I hope this helps :) hiddenlight-photography.com/nina-video-series

​@@Hidden.Light.Photography I'll take a look. Just about to go and polar aline and hope ive set n.i.n.a up correct 😊

I love that idea! I will see what I can do to implement that. Would you mind if I gave you credit for the idea?

Great question! Yes, you want the mount pointed north as a starting point. I always recommend a compass so you get it as close as possible this way you don’t run out of azimuth adjustment room :)

I love it and can do that :) would you mind if I credited you for the idea?

Thank you! That sounds very interesting, I need to check that out :)

Very good question! I prefer to use unscreen stars even though I pull my stars before stretching. Most say unscreen is best used if removing stars from stretched data, but I haven’t had any issues. Keep in mind though, I don’t reinsert my stars until after my data is stretched. If you are pulling stars on unstretched data and then putting them back in prior to stretching, I would use stars only image as I have seen and experienced issues putting unscreened stars back in unstretched (linear) data. I hope this helps :)

Thank you and you are very welcome! I’m happy this helps out :)

This is very interesting. Did you have the repository loaded prior or did you recently install?

Thank you and very good question :) I added this functionality since the script is pulling the information anyway. I use it as an initial check of my subframes to see if any subs stand out as different than the rest and easily isolate those frames from the rest. Subframe Selector is a very good tool as well and either one can be used. I just figured since the script is based on Star processing, it would be a good option to have :)

Very good question, I have seen that it is compatible on some forums, however, here is the GSS documentation: greenswamp.org/?docs=gs-server-overview#google_vignette

Thank you and you’re welcome! I’m glad this is helpful :)

Thank you and you’re very welcome! Seti Astro has done an absolute amazing job with his scripts and I’m happy he was able to take the time to be on the channel going over this :)
