Realising that not all image capturing and display software offers the same features, for those who do have them I wonder how many use the post-capture adjustments that they offer? For example ToupSky / Rising Sky etc. have quite a number of adjustments that can be applied to a snapshot of the video camera display. Although probably not as sophisticated as equivalent adjustments in separate dedicated post-processing software such as Photoshop, Pixinsight, etc. they are nevertheless quite effective and are, of course, immediately available for use during an imaging/viewing session. Typically I only use one or two of curves, brightness/contrast, denoise and sharpen. They take only moments to apply and can often greatly improve the camera's output. These before and after images show what I mean.
I don't recall mention of such adjustments being used with images posted here. But perhaps I'm wrong. It would be interesting to learn how often members use them, particularly when sharing their imaging/viewing sessions with others.

Nice result David! No, I don't use the post-process features in RisingSky. I've never even tried them out. As a RisingSky/ToupSky user (there's not many of us, with most people using Sharpcap ) I should have a play with these features one day.

Not having used the software, I had no idea of this,, sharpcap wise I use for my zwo but I don't use all it's features which is a shame,, I found that I don't have the time to read the how to posts on using software,, more into watching tutorial videos,, this is where howie has been a great help to me and many others with his tutorials on various pieces of Software. Me,, I personally like and prefer backyard eos,, just a pity it doesn't do likes of zwo cameras

David,I use Sharpcap but I am not aware there are any post processing features. I certainly use the histogram a lot but I dont regard it as post processing. The livestack saves the image as a Fits file . This needs to be compressed to jpeg to post it on the forum. I use Fitswork which has another histogram feature which I often use to darken or lighten the image further cheers Paul

isn't it all post-capture processing? Whether millisecond or many, you have to get an image before processing it...... The only difference is in the sophistication of the inter-face and options offered.
Hair-splitting. Still some what wet n windy here or warmer with clouds, not much of a choice. cheers all

Thanks for your replies. So far it would seem that the answer is “none'. Even 'though the sample is small the result is still interesting. It seems that the reason falls into two camps of which the larger is the use of SharpCap. And, as I understand it, SharpCap doesn't itself provide for post-acquisition adjustments. At the moment group or public viewing in a EAA session is not presently possible. Hopefully this pandemic will end some time soon and then we can get back to where EAA really comes into its own. While I enjoy the presently enforced solo sessions under the stars I'm looking forward to showing the night sky to visitors once again at outreach events. In that context my experience has been that applying one or two of the imaging software's available post-acquisition adjustments to a captured image can often create that much sought-after satisfying “Wow!” response from the viewers. As you may know, I use ToupSky as my viewing and image capturing program. The above composite image of some of its features shows the camera control / image capturing panel on the left. In the middle are the post-acquisition features (underlined in yellow) that I find to be most appropriate for EAA work. On the right is the Undo/Redo panel which can be a very useful feature in helping to convince visitors that the final view is “real” and that making any adjustments is not so very different from using a car's windscreen wipers to get a clearer view of the driver's way ahead (i.e. just clearing away the crud). Cheers David

David, I like your reasoning. When I do live demonstrations for visitors, or whenever I broadcast my Live view on the internet, I never do any post-processing. My intention is to show exactly what the camera sees, and what it is capable of without post-processing. Some say: "But why not make it look a little bit more pleasing for your viewers". Problem there for me is I like to see the excitement on their faces when they see a satellite drifting through the image, or the slow and steady movement (slow but noticeable) of an asteroid moving against the background star field, witnessing an actual occultation, etc. I personally prefer a Live show to be exactly that: Live. I could probably do a quick post-processed image to show them what could be done with a snap of an object. Might try that on visitors one night to see if they like it, if I remember. Also, your Toupsky looks different to my Toupsky and RisingSky. Mine has a black background.
I use RisingSky or ToupSky exclusively. I've used the rest '(sharpcap etc) and still prefer the Touptech software.

sorry mate, thought you would be up to speed with your favourite software of choice and threads of the last few months.... the 'drive' part is in reference to Rising Cam's link to the Rising Sky download site which they point one to for downloading said software. The ALS ref is the new live share software that was offered and discussed on the forum a month or so past, written by some French dudes. Very nice looking (the software) with features very relevant to this thread. clear enough for you now?

Ken. You are using "Obsidian Black" as your user interface style, as do I with the imaging laptop (see image at the top of this thread). The daytime-use desktop in the house has it set to the default "Windows" option.
Ian. You might like to try :

As I'm not a technically minded person, whenever I see anything technical come up, or anything to do with software, I usually go right on past and skip it. Half the threads in this Forum are beyond my understanding, or interest. I leave it to the Tech-heads to reply It's not that I am stupid, it's just that Tech doesn't interest me I'm old skool, and I like it that way
