Very new at this & struggling

Hi All,

I've been trying to process my Orion Nebula images using DSS & then processing in Afinity Photo (very similar in capability to Photoshop without the hefty price tag).

I have to admit, I have no idea what I am doing & I'm struggling to achieve any sort of result that is better than the original single shot straight out of the camera..

Attached is (1st pic) the low res cropped image from the camera & (2nd pic) the cropped result from DSS, I think it is about 17 images stacked...

When I try to then process in Affinity to bring out the nebulosity, it just gets very grainy & I struggle to get any colour adjustment, I haven't saved any of them because to be honest, they look like rubbish. I do understand that they were shot at ISO 6400 which introduces a lot of noise & grain.. it was my first attempt... I will be dialing back the ISO (when the rain stops.... one day)

My first question is about the result out of DSS, is this what I should expect?

I will have more questions to follow.. apart from having no clue about how to use the various programs I have effectively, I have no frame of reference on what I should or shouldn't be able to achieve with the data I have. I know it won't ever be as tight as some on here, I'm using an SCT on an alt/az mount...

Anyways.. hoping someone might be able to guide me along the way...
