    Will do. It’s based entirely on AstroPixel Processor, nothing fancy just working through tab 9

    I suppose it depends on what you are trying to achieve, but 30-60 minutes total integration time doesn’t seem very long for each image? This doesn’t seems right. I had an EQ6 pro and it really didn’t drop any subs due to the mount itself, but depending on the load, the wind would have an effect. 300s-600s were my normal duration. I did the rowan belt and this improved the mount a little, reducing backlash etc. But I wouldn’t do the mod until you have worked out why you are losing 50% of your subs. Unless it’s calm, there is a good chance you will lose quite a few subs, been there done that, but in the dome it’s perfect. The image scale is pretty low at 0.64”/px, not sure how the EQ6 would work out. But I love my SW250, it’s my galaxy imaging scope.

    I did crop it to the middle 1/3. There are some really funky galaxies in the full image, should post it later.

    I love M104. It’s just so low. You’ve done a really good job Mick.

    I'm working through my data, and after spending two evenings on this, I just cant get anywhere with it. There was haze in some of the later subs, so I chucked those, and ended up with far less data than I had hoped for. Plus the stars are bloated in the raw unstretched stack so I definitely overexposed too much with 300s subs. Just getting my bearings with the new camera. Here it is anyway Adam

    It looks pink overall, particularly noticeable in the galaxies (looks like the yellows are pinkish). I’ve attached my image as a comparison, but I think mines just slightly on the green side
  7. tooth_dr
    That’s good to hear, I do like APP. Did you run star colour calibration? I only ask because the image has a pink tinge to it
  8. tooth_dr
    What sort of exposure are you using? I can see my line moving between exposures presumably due to seeing. I would use 3-5s exposures with region of interest selected and just select a small area around the star in question.

    Lol not as much as that! Would you mind posting a photo of it fitted? Do you think I wound benefit from one too?
  10. tooth_dr
    I agree that’s amazing. Can’t beat a bit of aperture
  11. tooth_dr
    I’ll look into it 🤩🤩

    Thanks I follow the routine that you showed me for processing colour data in APP, and I have to say it's fantastic. Gone are my yellow images, and finally I have something that is vibrant - those blues and purples just pop out! I have some data on M108 that I took a few days ago, and I did a quick process with the same routine, and the colours just shine out. There is some tilt - it's worse on some targets and disappears on others depending on whereabouts in the sky I'm point. The focuser is a possible source, but the metal is so thin I think it could be from the metal tube itself bending/flexing around the focuser or even the mirror cell. I think I'm happy enough to live with it though, just glad to be getting something! The reflection has appeared before - do you remember my NGC4565 image last year there was similar streak? The secondary edges are not blackened at all, so that would be a good starting point, a job for the summer rainy days. I think it's one streak, but with dithering of 63 frames it has been smeared over a larger area.

    I was using SC myself with the camera, and definitely nothing like your green image.
  14. tooth_dr
    Some sort of electronic fault, at least it's getting sorted Incidentally all my images are green when I open them, but at least they are consistent lol

    I've never seen anything presented like that before with the constellations mapped out on the arms of the MW - totally fascinating and I've learnt something new today. Thank you.
  16. tooth_dr
    Cheers Dave. Thats bad about the camera. I'm sure I've only had about 20 hours of use from the camera in the past four months, and 95% of that has been in the last week.

    It's not specific to photoshop, it's a measurement of the pixels, where pure black is 0 and pure white is 255. If you go too low, then background value is close to 0 aka black. I find the values are useful to refer to because it gives me an actual value to aim for, takes out any guess work, and means the image 'should' look ok on a range of monitors. I dont know what software you are using, but there should be a mechanism in it to check areas of the image for this value.

    I've been trying to image a couple of galaxies per night, one pre and one post flip. On early Saturday morning at 1:30am I changed over to M82, and acquired 63 x 3 mins subs, OSC, totalling 3 hours and 9 minutes of data. Camera: ZWO 2600MC at -10 deg C, gain 100, offset 50 Telescope: Skywatcher 250PX (blue tube), 1200mm F4.7 Mount: Mesu e200 Guiding: ZWO OAGv2, 290MM, PHD2 Filters: None Software: APT for capture, APP and PS for processing I havent really had a chance to get much use out of this camera since I bought it in December, and I havent processed many OSC images before. I've a bit of work to do, but still very happy with the quality of the data for just 3 hours of integration time. I would like to add some Ha to this, but purposely didnt bother during the recent clear spell, as it was moonless nights and I gathered some broadband data on other targets instead. CC welcome. Adam

    This is a huge improvement over attempt #1, looks fantastic with all the detail. I opened the image up in PS, and the background value is about 3 or 4. Although M51 stands out, the background is just a little too dark for me, and I personally aim for 23-30 depending on the target.
  20. tooth_dr
    I've always noticed this too, end up going with what looks 'average'
  21. tooth_dr
    Very nice indeed. Just currently processing some M82 data myself, and I agree it's a fantastic target that deserves a bit of focal length.
  22. tooth_dr
    Thanks for sharing this one, hadnt seen it before in photos, it looks to have quite elongated arms.
  23. tooth_dr
    Damn nice looking scope that RC6, if it a heavy for the size of it?
  24. tooth_dr
    Looks good, was always intrigued by these scopes. If you dont mind, I think your flats arent right, and appear to be overcorrecting, and havent removed all the dust bunnies.
  25. tooth_dr
    Had a go myself at this too in 2019, I was equally amazed as you are @tomato
