Can't say enough how I appreciate your very slow and methodical tutorial- very clear and encouraging for all who want to learn the right way starting out! Thank you and please don't change a thing in your excellent videos!!!
This vid was genuinely so much help, living under Bortle 8 skies results in a fair bit of light pollution, your method of reducing this is easily the best I've seen so far. Thank you so much for making this, it's really helped tease out new details
This is the best tutorial I've seen, very easy to follow and you explain everything you do and why, thanks!
Thank you so much for your videos. I'm making progress by following along. There's times you had a mishap of over exposure while doing a subsequent change of Levels. You cancelled that iteration of Levels, and then reopened Levels to restart the iteration of Levels. I've found that if I click "reset" the immediately previous changes are set back to zero and I can begin again from the starting point with "that iteration" of changes. Clicking the reset button that's beside the cancel button does not reset the previous iterations of Levels. The same is true for Curves etc. Thanks again for all the time and effort you put into making videos.
Extremly helpful!!! Now I'm able to stretch the luminance without the need to pay monthly for a software. Please keep going with your excellent work. Best whishes from Heidelberg/GER
Thank you very much for the video. The more you talk the better I understand. It's helpful when you tell what you're wanting to accomplish before beginning your actions on a layer. Thanks again.
Three years later and this video is still useful. Got some tips I'm going to try with processing my recent stack of Orion. Though I only got about 5 minutes worth of data and didn't take and dark, flats, or bias images so I suspect it won't be as good as it could be, but I wanted to start small so I get the process down. Though I do have an older stack of Orion I may revisit and try processing again and see what I can pull out of it.
For subtracting the gradient, you can make a copy of your first stretch and then go to Filters->Enhance->Despeckle. Uncheck adaptive and then increase the radius to ~25 and the result should be the gradient without needing to manually make the gradient layer.
Thank you for the time in making these processing videos. They are all different from one another but as I watch them multiple times I start to understand more of what you are doing and try a different approach to specific problem . Getting a nice black background is not easy .
After several uses of GIMP I learned a worthwhile shortcut that has nothing to do with keys. After adjusting Levels and clicking OK if I left mouse click on the picture the Levels dialog reopens. As long as it's desired to repeat Levels just left mouse click on the picture again. It's the same for Curves, Saturation, Exposure etc. If I want to stop adjusting Levels and change to one of the other adjustment options, then I just go to the top tool bar and make the changes as shown in this video. You might have noticed the numbers in the Levels, Curves etc dialogs. You can click inside those dialogs on the number block and type in a number. When you click "OK" that makes the change on the picture in ratio to the number you typed in the block. If I make a mistake typing an input and the picture gets severely over / under exposed I just left click on the reset button in that dialog and type more carefully.
Thanks Nico, you're a legend!!
Thank you for walking me through DSS. Looking forward to your gimp session.
Thank you for your patience. A true teacher. I am very happy with the raw visual images I am able to capture but they deserve much more enhancement. I can't wait to give this tutorial a walk through after my next capture. I thank you Sir. You must be as truly passionate and in awe of this view of the cosmos that our technology now provides us, as I am. And to spend the time to bring others along with you .. is a gift. Is there perhaps a way you could provide a one-on-one or an internet classroom type of interaction like a Skype, or Messenger for example, ? Have you contacted the local colleges and universities to make your sessions valid of college credit ? Regardless, you are a good man and I thank you for your time.
Thanks so much for taking the time to go through this in detail. Being somewhat new to the hobby, it is greatly appreciated! I live in south Florida, right near the Florida Everglades - a great place for imaging! Hoping to to take your tutorials and put them to good use!
Thuroughly appreciate how you used a prgram you're not completely familiar with! Lots of times, tutorials are done at such a fast pace because the person is intimately familiar with the program, and it's difficult to keep up with what they're doing.
Thank you for the information, I was almost ready to quit trying to use this software, until watching your video. Great tutorial!
This is exactly what I’ve been looking for. Just started diving deeper into astrophotography with simple tripod shooting, DSS and GIMP. I’m hoping to get a tracking mount soon. Thanks for the video!
Wonderful job! I followed you step by step and I did a great job with my first ever M42 editing in GIMP. Thank you so much! I will keep an eye on your work.
Hi Nico, Hope you are well. I managed to get almost two hours of the Iris Nebula last night so this video will help immensely, thanks!
