Your tutorials on Gimp and Siril are so appreciated…please do more❤️😊🌷👍🏼

[@AstroOnBudget]

Thank you 😊 very kind.

As always Jeremiah - very helpful tutorial ! What I enjoy about your series of these processing tutorials is that they are straightforward, to the point, bite-sized gems that can only help improve the quality of the images we are processing. I have several images in mind that I will be trying this on ! Thanks again.

[@AstroOnBudget]

Eric you are such an encourager! Thank you. Have you had any word on GTI yet? I'd be keen to hear your thoughts about it once you've got it.

[@DrJ_MKE]

@@AstroOnBudget No word on the GTi yet... I may reach out to my supplier and inquire about any updates. Working without a GoTo mount is taxing my star hopping capabilities as I am sometimes struggling to find the necessary landmarks to get to my targets.

[@Mrcloc]

Oh my, I didn't know how to do this (the selection and deselection). This is unbelievably useful, thank you!

[@AstroOnBudget]

Glad it was helpful!

[@michakubisz535]

Great tutorial, thank you!

[@ChucoHiker]

Very helpful tip! Got my sub 👍👍

[@AstroOnBudget]

Awesome, thank you!

[@capsilver85]

Great thanks it worked for me also to correct chromatic aberration.

[@AstroOnBudget]

Great work! Well done Jose!

[@kevinjeansonne5081]

Just perfect small bites of learning GIMP. Actually just did my first post production of a stacked photo after watching your videos... stretching and color correction on Gilligans island Lagoon Nebula. Looking forward to apply your techniques of star reduction now and noise reduction...hopefully soon when the video comes out. Keep up the Great Work.

[@AstroOnBudget]

Thank you for the encouragement Kevin :)

[@avt_astro206]

Fantastic Tutorial Man!! I use The Exact technique For Doing star reduction in my Photos. I remember Someone else Posting a Video Of Star Reduction with Gimp! Its a Great Software!

[@AstroOnBudget]

Isn't not that complicated, is it? Gimp is excellent resource! Thanks for your encouragement 👍

[@michaelsachgau2970]

Fantastic! This is exactly what I needed! Subscribed!

[@AstroOnBudget]

Thank you Michael! :)

[@xaviut5201]

I was just looking for that, impressive! Thank you !

[@AstroOnBudget]

You are welcome :) How did you go performing star reduction?

[@moemode]

Thanks so much for this video . It's such a big help . Really enjoying the content. 👍

[@AstroOnBudget]

You are very ecouraging. Thank you indeed!

[@ziggyfrnds]

Thanks mate! That helped quite a lot.

[@AstroOnBudget]

Thanks Ziggy! How are you going? How's astrophotography going?

[@ziggyfrnds]

@@AstroOnBudget I'm doing well mate thank you! I've purchased a few upgrades for my astro photography gear just waiting for the guide scope and camera to arrive plus got a baader coma corrector next will be waiting for clear nights :D

[@AstroOnBudget]

@@ziggyfrnds Oh no! So the clouds are your fault! :) What Newt are you using?

[@ziggyfrnds]

@@AstroOnBudget Haha absolutely! I'm using a GSO/Bintel 8" F4, it's great but demands careful collimation. I was having problems with tilt I guess its because the GSO/Bintel coma corrector has a longer back focus requirement at 75mm. Might be the focuser too, I needed a 2 inch extension tube in the focuser to get the coma corrector into focus. I haven't tried the Baader cc yet but the focus plane is probably different (not sure though) and only needs 55mm back focus

[@juanmanuelsalas9644]

Great work. There are very very few sites on KZbin where they explain WITH FREE TOOLS like gimp or siril the astronomical photo processing. Congratulations. Please continue to teach us. Regards

[@AstroOnBudget]

Thank you very much Juan. Have you been using GIMP + SIRIL for long?

[@juanmanuelsalas9644]

@@AstroOnBudget Hi. I'm starting with siril. Gimp nothing at all. Regards

[@CharlieKallay]

I notice you haven't made any videos in quite some time. I hope you return soon. I really enjoy how you explain features that aren't usually used in GIMP. Looking forward to seeing you.

[@dumpydalekobservatory]

Another great tutorial using Gimp I've tried it in the past but really struggled with it but might give it another go.

[@AstroOnBudget]

Thanks buddy! Gimp is really a powerful tool. What do you usually use for processing?

[@dumpydalekobservatory]

@@AstroOnBudget I use an older version of Photoshop CS5 as I don't want to buy into a monthly subscription, I do some light stretching then remove the stars using Starnet 2, then I stretch the starless version until I'm happy & re add the stars after. I don't even use masks as I don't really know how to but the end results seem to look fine. I still need to work on my stars though as they always look to sharp need to soften them down a bit but slowly getting there & I've improved a hell of a lot these past few months to when I started this hobby years ago.

[@azrayastrophotography2260]

Thanks for the great information. I'll be looking forward to the noise reduction video. Cs

[@AstroOnBudget]

Thanks mate! You are producing excellent images. Keep it up!

[@robertleeimages]

This was great, only problem I've got is that I'm left with black dots everywhere but I'm doing it on a milkyway nightscape image

[@OlliesSpace]

Very cool tutorial pal. Do you use Starnet as well? very nice free standalone software for taking the stars out 👍

[@AstroOnBudget]

Yeah mate. Starnet ++ is a great tool for removing stars. I personally like images with stars. Do you usually perform star reduction on your images?

[@OlliesSpace]

@@AstroOnBudget Yep usually take them out work on the Nebula and put them back and then use curves on the star layer to reduce them. I've a little tutorial on my YT just in case you want a quick look.

[@dumpydalekobservatory]

@@OlliesSpace I'll have to look out for that one Ollie as I do a similar thing with mine apart from my stars always look a bit to sharp so need to soften them down a bit if that makes sense.

[@OlliesSpace]

@@dumpydalekobservatory Yep I think the curves thing would help the video is called How to use Starnet but it has how to reduce the stars in it. 👍

[@dineshnaik8494]

How do we get Threshold? I do not see it on my screen. Thank you.

[@christinekersting8898]

Awesome tutorial. Thanks sooo much.

[@AstroOnBudget]

Thank you Christine ☺️ do you use GIMP for processing?
