    I suppose you have to oversell it a bit in order to get clicks on Youtube. You guys seem rather familiar with Mark's Stretch, where as this video is my first introduction to it. Also, I would always trust the word of my fellow SGL members over a video I found on Youtube, haha.

    So I talked to the guy who made the video, this is what he had to say about the inquiries: So take from that what you will. Again I'm not very experienced when it comes to all of the technical details, all I know is that the process produces some very nice results from what I have seen so far. But there is no perfect process for every situation, what is described in the video can probably be improved upon in one way or another, but I'm not the person to ask when it comes to that. 😅

    Im not knowledgable enough to really comment on everything that you mentioned, but isn't a green color cast after debayering normal on the ZWO asi294? And for the second point, I see what you mean, it does seem a bit odd. But surely it doesn't change color balance too much, considering you are eyeballing the colorbalance, and you are only changing the black point per individual channel by only 1 - 2 positions.

    I doubt you would need anything too expensive. Many people just use a flashlight/torch, and I use my computer screen with a blank white screen displayed. Just make sure you are covering the aperture of your scope with a tightly pulled t-shirt or something similar so that the light is evenly dispersed.

    I just processed a picture I took a couple months ago because I only just got around to doing it. But I also just happened to stumble across an interesting YouTube video about a processing technique called the Arc Hyperbolic Sine Stretch. I decided on giving it a go on M57, and all I have to say is WOW! The technique did a great job of making the image feel very natural by preserving star color, and preventing them from becoming bloated. If anyone else is interested in it, here is the video. The image is about 1h 22m of 2m exposures from my SW 130PDS, and Canon 600D from my light polluted front yard.

    I finally got around to doing some more stuff with the good 'ole 130PDS! I used a new processing technique called the arc hyperbolic sine stretch to edit this image, and it has done absolute wonders to make the image feel more natural! Here's the link to the video in case anybody is interested.

    Looking good! I've been getting back into it as well.

    Here's M97 & M108 from Sunday, very impressed with how it turned out, especially during a full moon. 48 x 120s, ISO 800.
  9. Galen Gilmore
    That's fantastic, my first definitely didn't look like that.

    I don't have much else to post at the moment, so here is a reprocess of the Pleiades I took over 2 years ago. It really shows how much better I have become at editing my images, and how much detail you can really pull out if you do things right.

    I wasn't sure exactly where I should put this, so I put it here. Mods feel free to move it if you feel it belongs somewhere else. I have started a project to see if I can find an asteroid, comet, or dwarf planet using only my own equipment, and no prior knowledge of the locations of said objects. Mind you I don't want to discover one, that would be out of the reach of my equipment. To document my progress I have decided to make a series of Youtube videos that shows what I am doing, why I am doing it, and what I am learning. It has been a while since I have done any astronomy, or been on camera, so I hope I'm not embarrassing myself too much with this, as everything I recorded was done in the moment with no script or anything. Thanks for checking it out, if anybody has any tips or anything for me, feel free to tell me. edit: I just realized I have a typo in the video, please ignore that...

    Incase anybody is still on this thread, I have made a youtube video documenting what I did on the first night.

    I might consider holding off on the light pollution filter until you have started doing some basic imaging with it, as you might find you won't necessarily need it right away. Although I haven't used either filter, I have heard that some visual light pollution filters aren't quite suited to imaging, as they can upset the color balance quite a lot. But I'm sure others will provide more accurate and in-depth info than I can.
  14. Galen Gilmore
    I'm not really planning on trying to discover any, that is likely out of the reach of my equipment. This is just a little project/experiment I'm doing to learn about this kind of astronomy.
  15. Galen Gilmore
    Interesting idea, this actually removes the need to take multiple pictures of the same area of the sky, right? Thanks, I’ll try it.
  16. Galen Gilmore
    Anybody know of a piece of software that could detect the change the occurred in an image? I'm doing a project to see if I can find an asteroid or comet without any prior knowledge of where said asteroid/comet is. I'm not really sure where to look for something like this, so any help would be appreciated. Also, I would like something that could run on Mac. But I'll run it on bootcamp if there is no other options. Thanks.
  17. Galen Gilmore
    Thanks, was looking for a site like this.
  18. Galen Gilmore
    Always thought it would be cool to image a comet, absolutely not clue how I should go about doing it though. Anybody got any tips? Thanks.
  19. Galen Gilmore
    Nice job! The colors are great.
  20. Galen Gilmore
    Thank you! The star colors are one of the biggest improvements in this image compared to my other images. Thank you! Despite my busy schedule, astronomy always finds its way back into my free time.

    M35 Star Cluster in Gemini Equipment Details: -Skywatcher 130PDS -Skywatcher EQ5, R.A. Motors, unguided -Canon Rebel T3i, Astro Modified Acquisition Details: -30 x 2min Lights -6 x 2mins darks -20 Flats Processing: -Deep Sky Stacker (DSS) -Photoshop (Cropping out stacking artifacts -> leveling -> slight color balance -> small curve stretch -> remove vignetting using lasso tool -> crop again to put more focus on the clusters -> saturation and more color balance.) I was really proud of how this turned out. It may not look like much to you, but for someone who has below average equipment, and only has enough time to image during the weekends (when there is no moon, and it isn't cloudy mind you), this is great stuff for me. I also have heavy light pollution to my west, which causes a terrible gradient on any target even slightly west from the zenith. Thanks for looking!

    M35 cluster in Gemini | 60min total exposure. Really proud of this one, especially because of how little time I get to image at any given opportunity. Give me your opinions! Thanks! edit: and yes, I know I've got trailing stars, but I really didn't want to give up any exposure time by dropping frames.

    I am talking about the threads which clamp the two halfs of the ring together, not sure if what you said still applies. You're probably right about them being stripped, and not worn out.
  24. Galen Gilmore
    Where could you buy a new set of OTA rings for the PDS? Mine have worn out threads, so I effectively only have one working ring.
  25. Galen Gilmore
    That's what I was going to ask. The moon reflects light in all spectrums (white), which means that you can't simply block out the light with a filter. Unless I'm missing something here?
