HI . One Question. Sometimes, Nina Shows: Telescope Conexion Lost . Please, Reconect telescope. Do you know why? thanks

I've tried updating graxpert on the new update of pixinsight but it just keeps coming up with an error message, any ideas what I'm doing wrong?

Can you make a Hubble palette with a quadband filter like the Antilia Quadband?

lovely run through everything, great for a super newbie like this guy. Thanks!!

But if the dust is moving as well in the same motion then its gonna take waaaaay longer then if we imagine the dust just at a standstill

Just just to clarify. All those three screw sets (9 in total) are shipping screws? And the ones that face the front are collimating screws - correct?

Thank you for the clear directions. I now know how to handle multiple nights with separate calibration images for each nights. Just one point of clarification about your terminology around flats and dark flats. In your example the darks were shot at the same exposure time as the flats so they should be referred to as flat darks( or dark flats) and they will be used to calibrate your flats. If you want to calibrate your lights with darks those darks need to be the same exposure time as the lights.

i'm not exactly sure, if i had the same issue. Had to make a clean win install, and aftter installing PI graxpert could not run with some API error messsage even after installing graxpert. Then i tried to do a backgroundExtraction and it had to download the AI first to run it, the same with denoising, before it could run in PI...

Thank you so much, great video!

I just shot my first 50+ hour narrowband data set of NGC6960.... Trying to stack multiple nights in pixinsight my first time using it. All my experience up till now has been in Siril. Any chance you have a slower version of this I can follow along with?

Great!

Ok, so i just did my first big mono narrowband project. I thought id get two decent nights but ended up with SEVEN. So each night i shot one or maybe two filters. I did an autofocus every hour. So multiple filters had multiple focus settings. I have a Moonlite focuser with no backlash so i was able to take a set of flats for each set of lights with different focus settings.... I assume i can use my dark and bias frames with everything because i have a ZWO ASI1600mm Pro cooled camera. So do i just make each filter with its own focus setting specific flats as a different "night"? I ended up with well over 30 hours worth of total exposure. The target is NGC6960 veil nebula. I shot Ha, Oiii and Sii. I also shot Luminance for 2 hours with an hour each of red, green and blue to be used for stars. My narrowband subs are all 5 minites each. Luminance is 2 minutes and RGB are 1 minute each. Any thoughts are appreciated. Can make all the data available if you want to make a video out of it that i can follow along with ....

I wanna go there and meet the Ultras ウルトラマン

Perfectly explained as usual, Shawn. You've helped me so much over the years. Clear Skies! ✨

Pretty good - Thank You Question- i know have 3 rigs (different ZWO cameras). If they all shoot the same target, can i combine like this in WBPP? And, what i used filters on 2 rigs and not on 3rd rig, can i stack in WBPP? Thank You

how did you get nearly all of M31

Hey Shawn. I'll be imaging this target with my Askar FMA-180 Pro and my ASI-183MM. Of course, my plans will be weather dependent. 8-)

Nice tutorials. Straightforward. Concise. Very helpful.

Great video and content 🎉

Great informative presentation Thank you very much.

I’ve always found your videos clear and .concise. Being new to N.I.N.A. this is exactly what I need.

So just to be clear this is best applied before stretching the image?

alright but how fast was it sped up? what's the original frequency at?

Big help Shaun thankyou, Subbed Damo

Interesting process but it did essentially nothing on my image.

Beginner question... it needs to be super accurately polar aligned first,right? Thanks

is it possiblle that you do the optics also

Hi! Thanks that explains it nicely. Clear skies!

Hi ... I have an older version of GraXpert on my Win10 computer .... and I want to update to the latest AI version. I have seen that most people say that I need to delete the older version first .... but how??? I can't find any guidance on the GraXpert web site ... or anywhere else for that matter :-( GraXpert does not show up in the Control Panel/Programs list .... but I have found all sorts of files obviously linked to GraXpert on my C Drive ..... but I don't know if I should just delete all of these one by one .... or if there is a much better way of removing GraXpert before installing the latest version. Is anybody able to give me some advice about this? Mike

I think KZbin shorts have an issue: they don't seem to be publicly dated and it's difficult to tell when a video is from. Some are a bit outdated giving future dates but for a previous year.

Hope you see this and can answer my question. Can I attach this while my telescope in racked in so at 0 and can I use the computer to rack my telescope out to the 60mm im normally at for focus??

Hi Shawn. I'm just playing around with "HaRGB_Combine" with my Lagoon Neb data (2hr40min of RB & 1hr2min of Ha) and was wondering ...... if I had some extra Oiii or even Sii data would I be able to individually add them using the "HaRGB_Combine" by merely changing the "Ha" in the equations to "Oiii" or "Sii"? I'm going to try it anyway and hopefully I'll be able to grab some Oiii and Sii data soon but the Sydney weather here (Campbelltown actually...) is rather unpredictable at the moment. I'm just getting back into the Astrophotography after a break and frankly if it wasn't for your tutorials I'd be going a lot more insane than people think I am..... Thank you very much. Dave

We’re up to version 3.1 now. The binning is hidden in the filter settings. Make sure to open each filter’s settings to make sure the binning matches your images.

Curious, I installed 1.8.9-2 and there is no Gradient Correction in the process list. I see @axelp1972 also does not have it with the latest update.

Thanks for the video. Was going round in circles before this.

I just ran into this problem today! Lifesaver🤘

This is pretty much what I've been doing. Nicely explained. One problem I have is using this technique with a galaxy in the image.

Thank you again! I had to add comet Tsuchinshan-ATLAS.

I did this with good data (12 hours OSC, 4 hours Ha, F/4 Newt in Bortle 2) but got pink instead of red. Any suggestions? Thank you.

Das erste Volksteleskop mit Nachführung und kompakten Maßen. 👍🏻

This was helpful. I tried both of these things without success, but I realized from watching the video that the problem is probably with my star atlas. This technique works at home in my office testing, but not in the field, where the star atlas finds nothing.

I always appreciate your videos. Lean, practical and to the point. Just curious: You mentioned a student provided the data. What do you teach?

Hey Shawn - I know it's a old(er) post from you, but I have a question about automating the Sky Flats within the sequence in NINA - I used Voyager in the past and we could add a skyflat routine as part of the script for the evening/morning. The script would calculate the time to start the dawn sky flats and then proceed. Does NINA have something similar where I can add a "wait" to a NINA sequence that will wait for the appropriate time to start the flats and then proceed? Or must I manually try and figure out the time relative to morning twilight to start it manually?

thanks man

This software is a game changer for my Astrophotography love it .

Would love to see GraXpert star removal tool. Thx for the video

very handy - hate the music though

Please don't use misleading profile photos on your video indicating that graxpert denoise literally doesn't work. It's literally an indirect ad to use noisexterminator instead.

Thanks Shawn. Not sure about others experience but it seems you have to run the Graxpert local install and use the 2.0.0 denoise at least once (to force it to download the ai model) before the 2.0.0 model would show up in PixInsight.
