Thru the cheap but great in my opinion Nikon 70 - 200 lens a heap of 15 second exposures with no darks etc.
I liked the detail of the various dust lanes.

Thanks for the attempt to help me Bojan but the colour blindness prevents me even seeing a difference in many cases.
Blue can be purple or green can be brown..I just cant tell unfortunately.
I play with the colours until more detail jumps out..to me..which may not jump out for others..I dont know.
I try to get my daughter to help but I have exhausted her patience it seems.
I said somewhere else here today I am probably best just imaging in Ha so I get detail and dont mess up the colour.
Good job Alex, although I personally prefer the cross upright.

Which way is upright Raymo?
The thing rotates and stands on its head at times
But thank you for the encouragement I sure do appreciate your taking the time to do that.

Thank you Peter..the Deep Sky Stacker count was about 13000 stars I recall.
Please tell me do you see anything that indicates a problem with the lens..Its a $200( approx) Nikon 70 - 200 lens and well I really like the results I am getting but I am not sophisticated enough to see the flaws..Can you detect something that says spend $1000 on a lens to replace it.

Here is the image as it can out of DSS downsized to upload it only.
alex
Oh yes... that one is almost perfect.
What could be the purple band at the bottom?
Mirror vignetting?
As to uploading... you can reduce the quality in jpg (higher compressing) while retain the size.
Also, forum will accept 1~2MB, and the image will be automatically compressed further, down to ~200kB

Only one problem Alex, the price. Nikon's 70-200 ain't $200 ish.
Nikon's only 70-200 is the 70-200 f/2.8 (and more recent 70-200 f/4) which has existed/exists in various Full frame versions and depending on model is $2000-3500 new. Even second hand they are $1500-2000 depending on which model/age. You may mean the Nikon 55-200 or 55-300 or 70-300 which are all good lenses and designed for the DX / APS-c format. Unfortunately they are not in the same league as their fullframe friends the 70-200 f/2.8 VR or VRII or their predecessors 80-200 afs, afd, af, BUT they are extremely good and very sharp. I have seen remarkable images taken with some of these lenses (55-200, 55-300, also 18-140). I've also seen them coupled to an astrocam with great results.
Lookin' Good
Best
