  1. Adobe - If you have Photoshop CC 2018 (19.x) & earlier, Lightroom (1.x) or Lightroom Classic (2015.x) & earlier, stick with Mojave tops. Don’t upgrade to Catalina. These versions will never be patched to work with Catalina - Adobe REQUIRE you to have a valid subscription to more recent versions, all of which work fine with Catalina. An upgrade to Catalina may work for some CS6 onwards app (where the apps are already installed and functioning on an earlier version of MacOS), but you’ll be unable to clean-install these apps on a fresh install of Catalina as the installers are 32bit even tho the apps are 64bit. There are known glitches in CC versions prior to 20.x as it stands in Catalina betas that won’t be fixed (and Adobe have revoked all licenses for legit use of anything prior to these anyway cos they were naughty and illegally embedded Dolby technology without paying for it). See https://blog.conradchavez.com/2019/08/28/macos-10-15-catalina-will-adobe-software-work/. Anything CC2019 (20.x) onwards - ie: current versions available to CC subscribers - will work fine. PixInsight - "The current versions 1.8.x of PixInsight are only available as 64-bit applications for all supported operating systems. Please note that no 32-bit versions will be released anymore. Note also that any existing 32-bit version will no longer be supported or updated." - should be nothing to worry about here if using 1.8.x or above. APP - "APP runs on Linux (RPM & DEB), Windows & MacOS 64bits Operating Systems." implies it should be 64bit ready, but the APP chaps don’t go into much detail on sys requirements on their site unfortunately.
  2. I’m presuming you’re talking Sidecar, which lets you use a modern generation iPad as an extension screen - massively different to TeamViewer / VNC remote control... Install Duet on the Mac from AppStore, and Duet on the iPad for the pre-Catalina equivalent - s’been around since iPad 4 days. Catalina has it builtin and not requiring a separate app is all... However, you can set any Mac to create it’s own Adhoc WiFi network, and connect direct to it from iPad using ScreenSharing and VNC Client - no need for any WiFi router involvement. Click WiFi icon on Mac, and instead of joining a network, select "Create Network"... follow the process, then connect to that new network from iPad. Enable screen sharing on the Mac, install Mocha VNC on the iPad.
  3. Erm... no. All versions of PS can manipulate 8 & 16bit, since v3.x onwards (ie: pre CS1 days). All versions of Photoshop thru CS1 to CC2019 can manipulate 16bit images. SOME functions & plugins cannot operate on 32BIT images, and image must be converted to 16bit first (such as curves). None of this has any bearing on the o/p’s issue however.
  4. Enable ScreenSharing via System Preferences > Sharing. Use any VNC client on iPad. All Macs have had this builtin for 15+ years... no Internet Access required, just a local network.
  5. Measure continuity between ground and each optocoupler. When you press RA- or RA+ in PHD, it should close the signal between the relevant optocoupler output and ground. ST4 is rock bottom basics equivalent of 4 push switches.
  6. I use 3.65.5 (beta) without issue. See http://aptforum.com/phpbb/viewtopic.php?f=16&t=2260 for changelogs from 3.65 thru to 3.65.5. Anything above 3.65.1 has the expanded object list... The _next_ release (3.65.6) should feature full INDIgo integration.
  7. They've expanded APT with a further 18000 objects in latest betas... just tick the "show expanded object list" checkbox in lower left of the Objects browser pane if you're a paid-up user with access to the beta versions. Without it ticked you'll just get "the usuals".

  9. Nope - tis the same thing... Photoshop can operate in LAB color space and split into Lightness, A (Magenta/Green), B (Blue/Yellow). Should be under Edit > Convert to Profile > LAB Color (or something like that iirc - word of warning: do this on a finished flattened image, as it'll flatten it automatically as part of the conversion). Usually I do this on a copy of the final component images, to pick up the L layer, and then drop it on top layer back in my regular RGB composite and set layer blending to Luminance.

  11. Sorry - I worded badly... have a look at https://www.overclock.net/forum/62-peltiers-tec/121488-testing-undervolt-tec-air-cooled-3.html#post1319096 The original post they refer to there (which originally contained much more data for a wide range of manufacturers, and the validated test rig etc) over on HardwareAsylum looks to have been lost (altho I’m 90% certain the original thread was actually on procooling.com a few years prior - it _was_ 20yrs ago... my memory gets hazy).
  12. Insulating all exposed coldplate will also increase efficiency - you'll be losing a good chunk of cooling power to the air. Can improve efficiency further by finding a higher wattage/voltage etc and under powering it - look to PC TEC cooling forum archives for spreadsheets of make/model testing - getting you same wattage but for lower ampage at 12v = same cooling for less power consumption... amp-load saving can be dramatic

    Eastern Veil

    From the album: Marci’s Astropix

    1.5hrs exposure on the Eastern Veil 1.5hrs @ ISO800 EOS1000D FSM & Astronomik 12nm Ha Clip Filter Skywatcher 200PDS + NEQ6 Pro
  14. From the album: Marci’s Astropix

    a 2 pane mosaic, mainly as a result of bad polar alignment and a 30min cloud causing loss of guiding and massive drift whilst unattended. Perfect opportunity to practice stitching! 3hrs total exposure @ ISO800 EOS1000D FSM with Astronomik 12nm Ha Clip Skywatcher 200PDS + NEQ6 Pro

    Milky Way Timelapse

    That’s lovely... nice one!
  16. Hmmm - wherever the stars-at-night wordpress plugin pulls it from on our astro soc’s webpage: https://wakefieldastronomysociety.co.uk/sky-status/ EDIT: Which appears to be via the Heavens-above REST API...
  17. WiFi setup in what context? I just copy the same wpa-supplicant.conf across to all my Pi’s after install... https://weworkweplay.com/play/automatically-connect-a-raspberry-pi-to-a-wifi-network/ And yes, both INDI and ASCOM documentation on authoring drivers is _utterly_ pants.
  18. From the album: Marci’s Astropix

    Lost my patience trying to process any further than this. Light pollution is such an issue with this camera that it’s a fine line between subs being usable and completely trashed. Astronomik clip-in CLS CCD filter definitely needed. 1.5hrs @ISO800
  19. From the album: Marci’s Astropix

    An absolute swine to capture with a full-spectrum camera full of pubes & no CLS filter, thus hoovers in Wakefield’s light pollution, hence this is a grayscale image (otherwise the entire thing is tinted in an unremovable orange that swamped out any natural colour). Only an hour of data... 15x 240s @ ISO800D, EOS1000D (modified), Explorer 200PDS
  20. From the album: Marci’s Astropix

    My first foray into astrophotography... Canon EOS 650D, 200s subs @ISO400... no idea what total exposure was.

    M33 - Triangulum

    From the album: Marci’s Astropix

    15x240s@ISO800 Colour (EOS650D) 15x240s@ISO800 HII (EOS1000D FSM + 12nm HII)
  23. From the album: Marci’s Astropix

    10x360s@ISO400 Ha (EOS1000D FSM + 12nm HII) 15x240s@ISO800 Colour (EOS650D)
  24. From the album: Marci’s Astropix

    2hrs with EOS650D at 18Mp shooting visual colour range (240s subs @ ISO800), 1.5hrs with EOS1000D Full-spectrum-modified (no narrowband filters) at 10Mp (120s subs @ ISO800 as core blows out VERY easily in full spectrum). 5x dark frames and 20x bias frames for the EOS1000D session. No flats. Stacked in DSS 64bit with 2x drizzle, processed in Photoshop CC 2018 (very little needed doing to it to be honest, just pull the saturation up a bit to bring the colour out). This is a heavy crop hence the apparent low resolution of the final image. This was the last outing for the EOS650D before I killed it, hence no darks / bias applied to the subs from that camera - it died in process of taking it off mount to shoot darks etc whilst I packed everything else away.
