  1. Here are the star faults near the edge? Field curvature?
  2. Curious about what I assume is tilt in the m42 picture (NGC300 was almost at Zenith so makes sense there would be no tilt here) and the way stars are a bit hollow and have a kind of halo that points centrally at the edge of the field. I'm thinking a field flattener screwed into the drawtube might eliminate these issue or at least minimize them?
  3. Yep. I set up from scratch each time. The longer exposures I've taken seem to be dominated by light pollution. Maybe dropping down the ISO to 400 will help? I was thinking lots of shorter exposures would be better than a few long ones?
  4. This is more as result of finally getting everything working rather than as fully fleshed out images. M42 is comprised of 26x 1 minute exposures at ISO800. M30 is comprised of 4x 2 minute exposures at ISO800 and NGC300 is composed of 10x 2 minute exposures at ISO800. For M42 30x 1 minute Darks and 30x Flats (with Bias frames subtracted) were combined into a Master Dark and Master Flat. For M30 and NGC300 the Master Dark was comprised of only 10x 2 minute Darks and I used the same Master Flat. I processed the image in Nebulosity: subtracted darks and flats, Normalized Intensities, Batch Demosai
  5. Again not that this will be of much relevance to most but by specifying the Vendor ID of my Serial to USB cable in the properties box of the USB "new filter 1" I created in VirtualBox (ports/USB menu) to detect and access the cable in my virtual Windows machine I got EQMOD and the camera to work together and Cartes du Ciels slewing as well. Rapt! I'm assuming the blank filter in virtual box didn't allow the other filter to function properly. It could just be that I plugged everything in the right order too: scope on the everything connected before starting VirtualBox and Windows? Anyway it's g
  6. Setup: ProStar LP Mono (Touptek GCMOS01200KMA) Camera and Virtualbox 5.0 running Windows 10 (32bit) virtually on a 2011 MacBook Pro running OSX 11 (El Capitan) and (but not together!) EQMOD running a Skywatcher HEQ5 Pro mount. Seems almost pointless posting this as there are so many variables around which drivers are being used, which version of which software is being used, the age of the computer and its ports etc. etc. Anyway for what it's worth I did finally manage to get guiding but have one significant issue I'm hoping to solve! The Good The setting in VirtualBox 5.0 with
  7. This is the bigger image. Saturating the colour seemed to help bring some detail out.
  8. Starting to explore the processing side and tried the layering of images in GIMP. Seems like an iterative process of adjusting various sliders to see how they bring out detail, distort certain elements or clean them up. Lucky to have a tiny bit of time to try some things! Anyway below is what I managed to get from the the center of the nebula. The colour helped differentiate some elements is the end. Welcome suggestions though. As for being bitten by the AP bug, well the HEQ5 Pro is on its way :-) Still going unguided though....
  9. Astroplanner, Stellarium, SkySafari (on my iPad and iPhone), GIMP (free Photoshop like programme). The imaging I'm planning on (literally spent two nights on this!) is DSLR based, unguided, and basically without laptop. The image processing is what use the Mac for once I'm back indoors. If I have my Mac outside then it's usually in conjunction with my 12" Dob running Stellarium (finding stuff) and Astroplanner (recording observations and working through lists of objects) although mostly now I use Skyfarai Pro for both these tasks on my iPhone 6 Plus. The other thing I use on my Mac outside is
  10. I've started with Nebulosity and followed Astronomy Shed's video in regards to familiarizing myself with a workflow. Given all the hassle of trying to work around Windows I figured this is the simplest solution. I enjoyed trying it out first too and foun d it easy to grasp.
  11. Thought I'd attach an ISO800 2 minute unprocessed image, which I like more for colour. Colour is probably the area I feel least comfortable with and I'm really dishing up what Nebulosity is giving me. Is the processed image's whiteness due to overexposure? Would it have been better if I stacked more ISO800 images rather than included the ISO1600 frames?
  12. Bit more than a sketch now but after drift aligning the rest was kind of easy and I spent about a half hour processing it. Still hit and run so I figure the more efficient I can make everything the better
  13. The end result after combining 3 of the ISO1600 with 3 of the ISO800 pictures and subtracting the darks in Nebulosity.
  14. Yes, I am trying to avoid the laptop. It's another thing to carry and then that big 'ol slippery slope into AP proper!!! I spent a lot more time tonight drift aligning and got much closer (finally got all the W, N, E and S correctly Identidied) and my homemade Bahtinov worked a treat through live view on the camera. Only real issue is the time this all took (maybe an hour and a half or more) but figure if I have my Dob as well I can get some quality visual time in while I tweak the alignment. Got some shots of Eta Carina but from the moment I turned on the camera the battery warning started fl
  15. The other slight cheaper option and comparable to the Delos are the Vixen LVWs. Slightly smaller FoV but that's about it. Baader Hyeprions also have 20mm of eye relief, although the edges of the FoV are slightly softer than the Delos and LVWs, but are also cheaper again. I really quite liked my 5mm Hyperion when I had my f6 Dob, although it was pushing the maginifaction a bit. My absolute favourite though is the Pentax XW 7mm (214x for me, 171x for you) and occasionally, when conditions suit, my Pentax XW 5mm (300x for me, 240x for you). These all have the same 20mm eyerelief. Wonderful premiu
