  1. Sorry I haven't had the time to get back to this, but thanks for the advice. I guess I'll have to grab that adjuster and go from there, since none of my parts are getting me where I need to be. That word doc is super useful
  2. I had a go last night, and couldn't get it at all. Wasted an entire night of clearness on it I tried no spacer, 5mm, 10mm and 15mm, and then a 30mm nosepiece, then the nose pice into the adjuster supplied with it. Focussed all of those options, and all of them resulted in coma. Really not sure what I'm doing wrong. I'll post some pictures later so you can see what I'm doing
  3. So that's 75mm from the sensor to the 1st glass element? And you have the revelation astro, or the GSO? Nice pic!
  4. Hi all, I have a astro revelation coma corrector, and I can't work out quite what I'm doing with it. I went out a couple of nights ago and wasted a whole precious clear one while messing with trying to focus it and plate solve. It's frustrating as there's no manual I can find anywhere online, and I have no details at all with it... It's literally just an object to me lol. I want to know the spacing between the sensor and whether it changes the focal length. I've seen conflicting information all over the place for it - I was expecting to find a manual after I bought it that would make it
  5. Who bought the mount? I have a polarscope illuminator I can donate! (I might have broke mine the same way you did
  6. Thanks! I'll incorporate it into the training. After training for a while on the images above, I'm finding fairly poor results so far. If you're on this thread and you have usable images, I'd love and appreciate the help! We can make this thing better for everyone with a reflector
  7. These are the files I'm currently training with. I'm not getting great results, I think I need more nebulae that is background... I'm pretty new to shooting this stuff, and so that's why I was hoping to draw on other's images if they'd share I don't have many shots of H-alpha nebs. I think a good shot of the rosette would be good, or similar.
  8. No hijack at all, glad to generate the conversation. The idea is that you have to unfortunately manually edit the photos to remove the artefacts. The nature of the beast is that it's doing a removal and replacement of things it has seen before, and it'll never gove you a "true" image from a data sense. So I've been editing files to remove stars mainly using photoshop's content aware fill and healing brush. This gets you to a clean looking starless, but it's a bit of work! The idea then is to run the ai which does 90% of the work for you, and may be able to handle scenarios that are hard
  9. As an update to this, I managed to get the python versions correct, and have the neural net training on my own data. I have about 5 images that I de-starred and set as the training data, and have run 30 "epochs" so far. Aiming for around 100 before I retry the crescent nebula again. Anyone that can help, even with unedited, good examples of diffraction spikes that I can edit would be great!
  10. That bar is for it loading the resulting autosave, isn't it? I always save out a FITS, just to be sure anyway.
  11. To be clear what the issue is, this is how Starnet++ is handling my images at the moment: It doesn't know how to handle the diffraction spikes or the coma error. I'm hoping to help fix this with the retrain! If it can be shown coma stars and diffraction lines, it can learn to remove them.
  12. So I just started to try out Starnet++, and it's a super cool way of using a convolutional neural network to remove stars. The issue, as stated by the creator, is that it's trained using a dataset from a refractor scope, and so it doesn't work that well on reflectors, or any other scope type that has diffraction lines or any other focus aberration. So to train the AI, we need as many images as we can get our hands on, both preprocessed, and after having the stars removed, but shot with a reflector scope. I wanted to see if anyone is up for collaborating on it, so that we can get a lot of
  13. Hey Still out experimenting, took a shot last night of the Crescent nebula. Generally happy with it, but was wondering what I can do to boost up the signal of the "blueness" that some people get... Do we thinking the information is in there and will come out in processing, or do I need to filter for it specifically? If anyone has any pixinsight tips, I'd be happy to host my stack.... :)
  14. Yeah I think I'll keep an eye out for a guidescope. I chose this because I figured more magnification would result in better tracking, but I am super inexperienced, so who knows. lol
