  1. Et voila! Revisions including the DSE script - I think it is a nice finishing touch - thank you again Mark!
  2. Thank you - that script was meant to be the last thing I did, but I somehow forgot! You’re right, there are some areas in the image that could benefit from it.
  3. And here's the wider field original...
  4. Hi everyone! It's been a while... After struggling (and mostly failing!) with trying to image with an SCT for most of this year, I decided to go back to what I know for nebula season - my trusted widefield refractor! Blissful simplicity! I opted for the Hubble palette for tmy first Wizard, with a notable processing step being the first time use of StarNet in PixInsight for some starless treatment. Worked well! The final version is a crop - I'll include the original FOV in the next post. Shot from my back garden over the couple of clear nights we had this week, using a CEM25P, WOZ73, ASI1600MM Pro and Astrodon Filters. Captured using the marvellous Voyager and edited in PI. 12 hours of total integration. Full details here Thanks for looking! (And I'll come back to the SCT when I get a new mount!)
  5. I have one of these - easy to install and calibration simple. Frustratingly I've yet to produce a finished image yet with this setup due to calibration issues, but I can say that my capture software (Voyager, SharpCap and NINA) have worked perfectly with the autofocuser. I used SharpCap to find first focus and since then the other capture software gets on with it. Voyager, in particular, autofocuses intensively when producing it's V-curves at speed...the last night I imaged, Voyager must have autofocused 20 times as I specified, each time churning out a V-curve within a minute and the FWHMs were in the 1.8-2.4 arc second range on an Edge 8 aimed at M81. For imaging, I think it is a great solution. What's grinding my gears about it is that as I don't have a Celestron mount, I don't think it can be used for visual, unless I control the focuser with a computer or tablet...if anyone has worked out a way to hook up some sort of simple controller either directly to the focuser or via PC, I'm all ears!
  6. My CEM25P would keel over at that point!
  7. Thank you! I was just happy to see any stars at all in PHD2 after a night moving the ASI120 up and down on the OAG stalk to no avail! The guiding seemed incredible on the smaller scope too - was getting something like 0.2-0.3 pixels...flat blue and red lines...like the best ever! But one of the things I learned in the last few days, is what the numbers in the brackets in PHD2 means...i.e. arc seconds error...and why that is more important, so the smaller guidescope magnifies the error in arcseconds, which leads to bigger pixel error on the imaging scope at such a long focal length (if I've understood correctly). I DO think it is doable, though, as my mount has always had severe DEC backlash and I was pushing the payload too...actually when I move back to using my widefield refractor, I might think about using the miniscope for guiding, as PHD2 just seemed happier, you know? It is fun to challenge the conventional wisdom sometimes, as much as it cool to learn from more experienced imagers!
  8. Thank you! It's been painful at times before getting the first image, but I've learnt an enormous amount...both mechanically and software wise, PHD2 settings, getting platesolving to work at this scale, etc. As you say, I can definitely see where the improvements will come from!
  9. And here's the makeshift rig! My poor mount!
  10. Hi everyone, I've been into astrophotography for a couple of years now and I've largely relied on one scope - the William Optics ZS73 430mm refractor...an amazing piece of kit - I'm not sure I could've picked a better first ota to get into this hobby. I've been honing my skills and have become pretty decent, unafraid to aim my trusted frac at even tiny targets, knowing we would make a decent fist of it. So, I've only gone and got aperture fever and bought a blimming Edge HD 8! Back down the learning curve I go. For once, the new kit was accompanied by clear skies, so no time to carefully build the rig...get the thing on the mount and get outside! Ouch...clear night one was spent trying to cobble together a makeshift velcroed rig from my Z73 setup (the top dovetail was in the post), clear night 2 went utterly failing to resolve a guide star with the ASI120 and ZWO OAG (the ASI290 is in the post...eventually will move onto a Celestron OAG). Two clear nights without an image was too much to bear, so on night three, I just had to get something, anything, so stopped trying to do the right things - mount a 30mm miniguide scope (all I had!) to guide 2032mm focal length? Check. Use a barbell weight to desperately try to balance the OTA? Check. Leave all the wires hanging when imaging at F10 (the reducer is in the post)? Expect my CEM25P (no upgrade for a while) to cope with all this weight? Check. Anyway, I present M63 - sorry to break the run of all the stunners in galaxy season so far, but I am so happy to get any sort of image under my belt with a bunch of new kit and at a focal length way in advance of anything I've ever tried before. Misshapen stars, botched focus and lack of integration time, sure....but one of my most satisfying shots in a weird kind of way! Something to build on! Approx 3 hours of integration time. Thanks for looking and sorry for the long post!
  11. Hi everyone! Galaxy season is fun even for a small refractor! (Although some new equipment may have been delivered recently...with no discernible effect on the weather...) Leo's Triplet is a photogenic grouping. Apart from the three main actors, I didn't expect to see a very faint pair of what looks like interacting galaxies in the far left of the image, IC 2785 and IC 2786, which are 545-555 million light years away from us! In terms of the triplet, I think I like NGC 3628 the best visually. It is 35 million light years away and another cool fact is that its stars are apparently rotating in the opposite direction to its gas! 3.6 hours of LRGB integration time shot over two nights. Full details here Thanks for looking!
  12. I think it's stunning...I particularly love the diagonal framing!
  13. Thank you for the kind words everyone - good luck @TerryMcK...would that be the 183?
  14. And the wider original field...you can see how much I cropped in!
