    Julian Shaw's sombrero - with a surprise!

    The Sombrero is a top five galaxy for me, and this is a marvelous example.

    Looking and learning

    Some of life's most vivid memories come from the eyepiece of a telescope!
  8. Thanks, I'll check out the link. (What a great image, here!)

    M42 in RGB and Ha

    In a well-worn word, but a fitting one, awesome.
  10. I've been encasing my laptop, mouse and camera digital remote on a small table in a vinyl container on it's side with a quick snap-on lid into which I've installed a 75W light bulb, and that bulb keeps everything dry and warm(ish). Last night (Friday) I imaged for several hours at -18C here in Ottawa, Ontario, with no issues, and a clean dry laptop when finished. It works wonders.
  11. I have Affinity on my list of potential software. Now that I have a 64-bit operating system I will look into it. What I like about it thus far is that you can buy it, rather than continuous monthly subscription, and it has good reviews as an alternative.
  12. Hi, thanks for responding. I'm beginning to realize that processing the data is pretty much everything when it comes to Orion, and that surely must be the case with all other data as well, which makes sense. I just got a dedicated laptop for the scope and data processing, as my old one was running 32-bit Windows and Gimp imaging led to crashes, so I should be good to go with Gimp, but AdobeCC ($!) will have to wait a while, yet. So much to learn, and such weather to learn in. I got 40 minutes of Orion data last night (8x5m between two trees!) but set-up was in -18C and tear-down was -20C (Ottawa, Ontario), and my limited experience and the continuous crappy weather not giving me a chance to practice, set-up was long and brutal even with hand and toe warmers! Tear-down was as fast as humanly possible, all the stiff cables and ice-cold paraphernalia quickly placed in the covered plastic container I use to keep the laptop and camera remote warm (I have a lightbulb on inside), and the whole mess then laid out in the den to warm up and dry off before repacking. My wife is beyond thinking I've lost my mind, given the fact that I've been out with the Dob so often in cold weather that she's given up trying to analyze what makes a man do such a thing voluntarily time after time. And now this. We have an unspoken agreement, I think: I don't question the strange stuff she does and vice-versa!
  13. Hello, again, thanks for the link. I checked out the video, but he does not explain how he manages to achieve the spectacular final image with such core detail shown at the end, other than a couple of hints, being 'hundreds' of ten-second images combined with many three-minute images for a total of several hours of data. He does not mention any special changes to the camera settings during imaging, which leads me to believe that he is somehow using the ten-second images for the core and the long-exposure images for the outer structure, though in what way is not mentioned. P.S. I just found his U-tube video on processing all (3h, 8m) of the Orion data in AdobeCC, and he mentions using just the default parameters in DSS and removing the final stacked image straight to Adobe without any alterations, so that tells me that his final image is achieved stricly through Adobe processing. I willl now watch that video in it's entirety, but I will not be able to use the help for a while, because I do not yet have Adobe Photoshop. I just shelled out for a dedicated laptop for running the scope and processing the data and have used up my financial 'allowance' for a while. All this info is great to have, however, as at some point this year I will have the software and hopefully the data and more experience to achieve better results.
  14. How do I prevent core blowout of my M42 image? I have 8x5minute quality light frames plus 12ds, 12fs, and 12bs. When I stack them (DSS) the core is obviously already blown, and removal without any DSS processing (I believe the recommended procedure) straight to Gimp is no help, the core is blown no matter what I do. I'm using the APO equipment listed in signature, with the modded Canon T6i (750D) and D1 LP filter. Is it just a matter of filters (Ha, etc.) which I don't have yet ($!!!) or is there something I can do during imaging or before stacking to prevent or at least minimize core blowout?

    Very nice. In my limited time at this new hobby I've only managed a try at M38 once, and your image blows it away. I hope to have something comparable in the future!
