I am new to editing Raw photos. I shoot mainly Wildlife, but have just bought a Nikon D850 to shoot more landscapes(by the way I’m finding it even better for wildlife than my D500). I have been playing around with some of the free software(Capture NX-D), but have found it limited for my use. I have got a copy of Affinity(an impulse buy as it was half price),but have not really got to grips with it yet. Recently, I have downloaded a trial of Capture One Pro 20 and with a bit of reading up and a few on-line tutorials I’m finding it really easy to use and am very impressed by its sharpening and noise reduction capabilities. My question is, if I go down the Capture One route am I missing out on anything extra that Lightroom or Photoshop have to offer.

Hi, I'm definitely not the best resource here. But, the earth rotates and makes pictures of stars into "trails" with longer exposures. You said you don't have a telescope or star tracker mount. Due to technology we can now use, our camera sensors allow us to record multiple recorded images of a star, etc. before it is blurred by the earth's rotation. Stacking these images will combine the un-blurred images into one. Other exposures, like a dark field, will record the way that the software will treat the non-stellar areas of your image as 'black', increasing the contrast and appearance of your stellar images.
