  1. Here's my modified HOO attempt. Good luck to everyone, there's already so many stunning renditions! Processing done in Pixinsight. Here are my brief steps that I took for Ha and OIII: Deconvolution StarMask Extract Lum, stretch and create range mask for highest areas of signal Get PSF using PSFImage script Applied 20 iterations of deconvolution Stretched Lum out to 75% along the histogram for an MLT mask Applied a subtle amount of MLT to both filters Non Linear Stage: Stretched using HistogramTransformation Used Jon Rista's masks method for TGV for both filters Applied small amount of TGV to Ha and a little more to OIII PixelMath combination of R = Ha, G = OIII*0.5+Ha*0.5, B = OIII Starnet++ to get rid of stars Curves transformation for saturation and overall brightness ColourMask for the blues RangeMask and CloneStamp to get rid of residual background and only exposing the crescent itself Curves just for the blue outer shell ExponentialTransform to brighten nebula LocalHistogramEqualization for constrast UnsharpMask for more crispiness DarkStructureEnchance StarMask and MorphologicalTransformation for smaller stars
  2. Just received my new EAF for my TS Optics 90mm CF that has the 2.5 inch R&P focuser. Issue is that there's no direct holes for the focuser bracket to go into, so I've had to take the grub screws out and replace them with longer ones so the bracket will go on securely. The other issue is that because the focus lock is in the way, I've had to take that out but now since it blocks the bracket going on, the focuser wobbles Here's a picture of before I installed the bracket The only idea I have is to drill out a hole in the bracket big enough for the focus lock screw to go in. Any help would be appreciated Matt
  3. Always had some kind of trouble with guiding and I'm wondering how can I further improve it? I have a HEQ5 Pro and my payload is around 7kg with everything attached. I ran the guiding assistant in PHD2 and the backlash came back at an insane value of 9000ms, so my best guess is to only guide it in one direction. Just how do you know which direction to guide in? I have the rowan belt mod and I've adjusted the worm on both RA and DEC and did tension the DEC a bit more as it did seem a bit loose. This guide log is only after the worm adjustment and not the tensioning. I'm going out tonight to see but I want to try and get the total RMS to be stable below 1 arc second if possible and was wondering if anyone could help? The log isn't very long as it was a test run before things got cloudy the other night but should give a good idea Matt PHD2_GuideLog_2020-09-15_004500.txt
  4. Me too, gives a different feeling to the image Matt
  5. NGC 7000 North America Nebula Imaging telescope: TS Optics TS Photoline 90mm f6,6 Triplet FPL53 Apo CF Imaging camera: ZWO ASI 1600MM Pro Mount: Skywatcher HEQ5 Pro (belt mod.) ZWO Ha 31mm 7nm: 30x300" (gain: 139.00) -15C bin 1x1 Integration: 2.5 hours Managed to fix a few issues with tilt but it's not totally gone, rather it's acceptable. Would like it gone, but there has to be some compromises and I also can't seem to undo the 2 inch compression ring adapter and put a threaded connection in place because the threads are extremely tight and can't undo them at all.
  6. I have a 1600mm linked up with my fw and guide camera and I'm using kstars with ekos on the latest stable astroberry version on an RPi 4 I went out the other night and the some of the images started popping up only being half downloaded it looked like. I've set the highspeed to 1 and checked auto bandwidth but nothing would fix it. I've attached an image of what it looks like.
  7. I had one last go at this data and wasn't able to get a better result than my previous, especially in the core which is what I wanted to focus on. This challenge has really pushed me and this was the first time processing in SHO too. Thank you FLO and IKO for making this possible and working with such good data. One thing I would've loved was to get a drizzled integration so you can push the resolution and limits in the core to make it nice and crispy and defined. Here's a rotated version since I like it more and a cropped, zoomed in one Good luck everyone!
  8. Had another go with more time on it. Tried hard not to go overboard on the sharpening this time and focus more on the core If you zoom in on the core, you can tell a noticeable difference, although it's less apparent zoomed out
  9. First try at the data. Might have another go before the 4th to see if I can get more from the pillars but happy with the result nonetheless.
  10. Ended up coming back to this data and reprocessing it. Was such a monster of a mosaic to do
  11. I'm buying a DSD DC Hub 2 and a Raspberry PI and wanting to mount them to the side of my telescope. Is sticking velcro on the telescope it being a round surface safe for not falling off okay? Also will peeling the sticky side off, damage the scopes cosmetics? My other idea would be getting an aluminium plate, drilling a couple of holes and mounting it where my guide scope would go, allowing space for mounting both. Anyone have any other mounting ideas?
  12. Ah yes, I suppose so. Well now it's just a bent piece of metal so can't do much about that
  13. Just had a go again and ended up snapping something on the end, although I don't think it was a critical part, just a ring threaded on the opposite end of the focuser. I'll just have to cope with the fact that I'll probably never get it undone, but oh well, living with a bit of tilt won't be the end of the world
  14. Would it be also worth to put it in the freezer for a few hours and try then?
  15. The most pressure I was able to apply was just after I made it very hot with the hairdryer was have my dad take one strap wrench and turn that clockwise at the bottom while I go from the top and turn anti-clockwise. I put all my arm grease into that, and it still didn't budge at all. This might be me being stupid but surely if you heat it and make it expand, will it lock the threads together more?
  16. Just tried heating it up with a hairdryer until hot and trying with the strap wrench but that still doesn't work
  17. I'm unable to unscrew the compression ring adapter on my focuser to be able to have a threaded connection to mitigate tilt. I've tried a strap wrench, soles of shoes, rubber gloves, table tennis bats but it's that tight that it just won't come undone. Has anyone got anymore ideas how to get it undone?
  18. Was rather humid and there was a lot of dew on a box I left out there last night
  19. I want to be able to do around 10 hours (5 Ha, 5 OIII) if the weather let's me but that might take a while seeing as it's England
