  1. Excellent rework, Andrew. I like this palette more than the original. Just for kicks: apply scnr green with default settings on that last image and see where that leaves you.
  2. What am I missing here? What is the advantage of a bino telescope over a bino eyepiece? Other than comfort, that is.
  3. Did you read the edited reply? Unless you get the synscan upgrade, you won't have goto. This upgrade is more expensive than the other offers. But regardless of which upgrade you get, if it includes dec, you won't have to touch the mount to center a target. Hence less vibrations that can throw pointing off. Also check which upgrades allow guiding (st4 port).
  4. If you have an osc, and only occasionaly want to spice up your images with nb from a light polluted site, then why not. But I wouldn't recommend it as a replacement for individual nb filters. Usually the three components, Ha, Oiii and Sii are at very different intensities and need individual treatment to get best results.
  5. Go for dual. Only if polar alignment is spot on, will tracking in RA only suffice. You need dec control if you want to guide. Dual motors also make it easier to slew to targets. Without the dec motor you still have to touch the mount in oder to point to a target. This introduces vibration. Dual motors should also increase the resale value of the mount.
  6. That's a nice little gem, but I agree, a longer fl would be a better fit. If you deemphasize the surrounding stars, the double cluster will stand out more. To do this, create a star mask. Erase its cluster stars. Then apply and shrink the stars. This will shrink the stars that are not part of the clusters. A bit of artistic license. I wouldn't shrink the largest stars much. Leaving those will create a more natural night sky look.
  7. At 130 it's a bargain, imo. But the ota weighs 5 kg, and is at the load limit of your mount. Otoh, it's a standard imaging combination, sold by skywatcher resellers. It's also the combination I started with (150pds + eq3 pro). As long as your long term intention is to upgrade your mount, I'd say go for it. Just keep in mind, you absolutely still need tracking. Maybe sell the 150 pl?
  8. That actually makes sense, since with a 12 bit ADC (zwo cameras) the 12 bit output is stored in the high end of a 16 bit word; 1 ADU = 16 DN. (16 = 2^4 where 4 =16 - 12.) 0.48 e/ADU = 0.48/16 e/DN = 0.03 e/DN Good thing I wrote "afaIk" before, because I didn't then, but now I know farther. Always nice to learn new stuff.
  9. AfaIk, DN and ADU are the same, a digital unit. Otherwise, I can't help, I've never come to grips with Mure denoise.
  10. If you're imaging from a lp area (bortle 8+), you should probably reconsider the dslr as an option. Mono + rgb is generally more lp-proof than osc because rgb filters have a transmission gap at the most dominant wavelengths for light pollution sources. Some rgb filters are better in this respect than others. You may also need to adopt a different data collection method than standard lrgb, because your luminance will collect all the light pollution. Rgb filters combined with Ha and Oiii in a 5 filter wheel and a camera with a smaller sensor may be the way to go.
  11. The OP's view on that was given in the original post: Performance-wise one could go either way, imo.
  12. Another no brainer: pixinsight; since you can't do anything with your data without processing software, and Gimp crashes/is limited.
  13. Your stars are out of focus. Seriously though, nice setup.
  14. I know, hence the . The asiair pro must have a power adapter built in.
  15. So, how is this pro-gadget powered? Through usb-c with step up converters to get 12 V out? The zwo- & dslr only support is probably a combination of strategy and licensing issues. Does anyone know if it's possible to test the app without buying the hardware?
