Hi,

Thinking of trying to get my hands on something a little better than GIMP for my Astro Image Processing (something that supports 16 bit images).
(and basically Adobe Photoshop is too expensive for me)
I expect this has been discussed many times, but does anyone use Cyberlink PhotoDirector 9 (£47.99), or Serif Affinity Photo for Windows (£48.99) for their post DSS Image Processing?
The reviews on the above programs are very good indeed on the internet (ie) Tech Radar
I look forward to any recommendations or advice from those that might know please.

Regards
Steve

I couldn't even get GIMP to load my stacked image from DSS, so if you can do that you're doing better than me. I'll be interested in what other people recommend as an alternative. I don't have a problem paying for software, but I do find the Adobe subscription model a bit overpriced for my wallet as well.

Gimp 2.9.x does 16bit and will load the TIFFs that DSS makes (for me anyway!) so we need to explore what is going wrong here :)

Give me a mo. and I'll dig out some links.

Hm, Gimp in version 2.9 is capable of working with both 16bit and 32bit images, no problem, it also loads fits files with no trouble. I've been using it quite some time now.

Gimp 2.9 is still development version (but quite stable), so you don't get compiled binary for windows on Gimp website - it offers only 2.8 version. Luckily development version compiled for windows is available here:

https://www.partha.com/

There is download section on right side a bit down the page:

image.png.0edb923fafe442cc1c7777bd6d271a78.png

So you can download Standard edition (installer) or Standard Edition portable - if you don't want to install it - just unzip to folder and you can start it there (just delete if you no longer want to use it, no need for uninstall).

Thanks @vlaiv partha was one that I was going to dig out ! The portable versions are the only ones I have used and they can be slow (on my m/c anyway) comes with RawTherape built in, so can load directly your raws (uses DCRAW)

Samj builds portable 2.9.x frequently, faster more responsive but no built in raw handler ( not a prob if using DSS TIFF output ) she is looking into RawTherapee vs. Darktable

I use Serif Affinity Photo for general photographic work and for astro post-processing.  I've never had or learnt Photoshop, and couldn't get on with Gimp.  I'm on a Mac, but I presume the Windows version is just as good.  Affinity does have a stacking mode, and if I want to stack some lights from a session - being lazy, keen to see a quick result! - I'll stack and post-process purely in Affinity.  I'm no expert though, but I enjoy using Affinity very much and find its capabilities more than enough for my needs.  I also reckon its excellent value for money.

PS Partha only builds for x64 so if one wants to use a heritage x32 m/c for imaging whilst the domestic staff use the new one-  :)  -Samj does both in the same zip, so download (look for the téléchargement bit !), extract, delete the not needed bits and use economically.

Slowly the domestic allows me time ! : to find&post some of the other ones :)

http://www.astro.louisville.edu/software/astroimagej/

a variant of

https://imagej.nih.gov/ij/

and not forgetting classical IRIS ( but if you thought Gimp was a learning curve beware!) http://www.astrosurf.com/buil/iris-software.html very good but needs time to sus out all its capabilities.

There is a newcomer variant to IRIS - SIRIL   https://free-astro.org/index.php/Siril which I have not yet tried so ymmv.

All the above are free BTW

I too vote for gimp... Latest version should load all 16bit data for you. Yes it's a rougher version of Photoshop, but one you're used to it, it'll do everything you need... 

Alternatives are really only photoshop and PixInsight IMHO.

Affinity isn't too great on automatic hot pixel removal - I didn't realise this was a feature on Photoshop until I stopped using it when the subscription model came in. Granted, stacking can do the job but it was an nice feature, especially on single sub astro-widefield lanscape stuff.

Apart from that, I have adapted Affinity products into my profession and can say it really passes muster. It also supports 16 bit and 32 bit RGB HDR.

Adobe creative cloud is only £12 a month and you get lightroom and photoshop for that.you also have access to adobe portfolio where you can build your own free website. 

I tried paintshop pro couldn’t get on with it

for me I’d choose PS over any of the others out there it’s a lot easier to navigate.

Paint Shop Pro is a lot cheaper than PS, and 'some' of the PS plugins are compatible... 

But if you can get hold of an OLD version of PS (I use v7) i.e. non-subscription, it is still possible to install & run on windows 10

I consider processing software an important part of my imaging setup. And as such, I saved up to "buy once, cry once". PS had (has?) two main disadvantages:

1, it isn't a complete package; you still need stacking software. And you may also need to buy plugins or "actions".

2, it uses a subscription plan, which makes it more expensive in the long run.

These were two important reasons why I bought PixInsight, other than its extensive list of features.

Alternatives to PS and PI are startools and APP (astro pixel processor), but I have no experience with either of these.

I have not used it myself by I have heard good things about APP.  As stated above you can often find an older version of PS on Ebay anything from CS2 onwards should be OK.  I use CS3 and works fine.   Might be worth a look.

I use paintshoppro and StarTools with DSS or Sequator for stacking.

Psp I can use both hasta le vista green and gradient exterminator. It is ps scripts that won't ruin in psp but plugins generally are ok.

Every now and then a full license of psp is on offer at £19.99.

Cs5 is a bit of a disaster on win10 pro. Plenty of erroneous 'not enough RAM' warnings and very, very slow.

I moved from Photoshop CS6 to Affinity photo because PS would not support my new camera RAWs and to be honest I struggle to find a blind bit of difference in features and operation between the two, if anything Affinity has more.

I use the tiff saved from StarTools into PSP. Is that not 32bit? I need to go find out.

Edit: Startools saves as 16bit tiff.

Looks good for £48 ... but only 16 bit filters.

IF I had a clue how to do it I would write a program just dedicated to doing stretches, levels and curves on 32 bit images, with statistical analysis to automatically maximise dynamic range without clipping.

I expect DCRAW does, use that to convert to a format that suits PS if you like doing things in PS

is it your 80d ? dcraw lists it.

      This is maybe my 3rd attempt at a galaxy and I am trying to figure out the best way of doing it since I live in a red zone of London suburbs.
      I took this over 2 nights (well, 1.5 really, as my guiding wasn't working and plate solver wouldn't comply after meridian flip...) with my 8" EdgeHD SCT with 0.7x reducer and Atik 490X. Around 20 Luminance subs at 10 mins each  (1x1) and around 15 RGB subs at 5 mins each, but binned 2x2. I use Astrodon filters but also have an LP filter permanently in my image train. 
      Question: should I only use RGB and create a synthetic L channel, given LP, or continue trying with the actual luminance? Gradients are horrible with luminance but RGB doesn't have as much detail (only red filter seems to be more sensitive).
      My stars are all over the place (colours pop out everywhere, in the wrong way), how can I control this better?
      Also, as I wrote, the red filter seems to have much more detail than the rest and when I add all the channels into PS, the red colour just overpowers everything (and in general, how can I keep the star colours as they are and not have the red and blue go crazy - I am not sure the name for it, but it looks like chromatic aberration on steroids).
      Any other general tips would be great...
      Thank in advance. GFA
      PS: I cheated with the core: just changed the temperature to make it look a bit more glowy; for some reason, I barely had any yellow colour from the data...I will post stacked images, if of interest.

      I wasn't sure where to post this tip....it is probably of most use here....
      Many of us with observatories or indoor Mission Control use Windows 10 Pro Remote Desktop to control a scope side computer running camera and scope control software from a second computer indoors. This works superbly at 1080p resolution.
      However, I have struggled for a year trying to perfect a wireless solution that works with 4K UHD cameras terminating in a 4K UHD display.  Until now, whilst cat 6 cable does work fine, wireless even at 5Ghz 802.11ac has struggled with some lag and poor performance. I have spent a fortune upgrading wireless adapters and range extenders, but this isn't the issue!
      Here is a solution;
      1.  Seperate your dual band network into distinct 5Ghz and 2.4 Ghz channels.
      This is easy with  (say) a BT Home Hub. If you don't do this, it can be a bit hit or miss whether your 5 Ghz wireless adapters connect to the right channel. You will now see TWO channels, one at 2.4 Ghz with a suffix like <hub name> and another at 5 Ghz named <hub name -5>. Connect your 5Ghz adapters to the latter. If your internal adapters are merely 2.4Ghz, you can disable them via Device Manager and plug in a USB version costing around £5. Note that at 5 Ghz wireless range might drop. If so, a Netgear EX8000 wireless extender is recommended as it employs 'mesh' technology. 
      2. ONLY if you have a fast network, and powerful CPUs and quality graphics card, try DISABLE 'RemoteFX compression' in RDP.
      This allows uncompressed screen data to flow across RDP.  I have found this improves performance whether using 802.11ac wireless or cat 6 cable. What RemoteFX compression appears to do is limit effective RDP speeds to under 10Mbps (due to translation times). That is crazy if you have 433 Mbps adapters,  and an 802.11ac network (or catv6 cable). Unleash the beast! Send across uncompressed data! The issue is not with speed or bandwidth, it is an artificially imposed limit in RDP.
      To do this type 'Edit Group Policy' in the Windows 10 Pro search box (doesn't work in Win 10 Home). You need to drill down through about five levels of Windows Configeration Folders, and Administration Templates and Remote Desktop Services/Host folders to find a utility named <Edit RemoteFX Compression>. In that, your options are <disable> compression or <enable> a compromise mode.
      If you don't know how to do this try Googling 'Disabling RemoteFX Compression' to find a lengthy Microsoft tutorial. Or visit https://docs.microsoft.com/en-us/windows-server/administration/performance-tuning/role/remote-desktop/session-hosts .
      I deliberately don't here state the quick route sequence to access this deeply embedded network utility command because you are delving deep into developer/administrator territory and do need to understand what you are doing and how to revert to your original RDP settings if your network can't handle these levels of uncompressed screen data. We don't want any novice attempting this on a cheap Compute Stick on an inadequate network!
      3.  When employing RDP from your computer indoors, select <WAN 10 Mbps> or <LAN 10 Mbps> as appropriate via <Options><Experience>. The default <auto-select my connectivity> often selects too low an option. The irony here is you can select this and still not enjoy faster speeds unless you have edited/disabled RemoteFX compression.
      I now have Atik Infinity plus CPWI software running in an end to end 4K UHD system terminating in a 4K UHD monitor. Over 802.11ac wireless it is now rock steady.  Over cat 6 cable my system is now turbo powered. If you don't need RemoteFX Compression, don't let it restrict your network performance. It is evidently set to ensure it works on lowest common denominator networks. If you have a fast network/CPU, disable RemoteFX compression and finally release the beast of 4k UHD over RDP.

      I gave a demonstration/workshop at my local Astro Group* about a simple way of removing light pollution from an Astro Photo. 
      The description I gave was deliberately for beginners, using a wide angle tripod shot photo and using one of the easiest packages to get to grips with (Paint.net). 
      The attached pdf covers the basic technique. 
      I'd appreciate any feedback on it.

      Hey all,
      I took some really rough images of M42 the other night, alignment and focus was by eye, heavily light polluted, no calibration frames and I have a dusty corrector plate. However, this was the first time I have shot a deep sky object and for how rough it was I was pleased, see attached.
      I watched a lot of DSS tutorial videos last night and I decided to stack the 16 images I have just to see what I get. Now, I am under no delusions as to the expected quality of the final image however, stacking made all the stars vanish and the overall quality of the image was less that that of a single frame. Any suggestions? I do not have an example image saved, sorry.
      Thank you.
