David Malin stayed at Noel's home back in 1987 on a visit to N.Z. David set his 10x8 of NGC 253 next to ours and we stood about 4m away. The colour was the same, but even at that distance the grain structure difference was obvious. One through a 12 inch f/7 Newtonian, the other through the Anglo-Australian 48 inch Schmidt! But the colour was good so we were happy.
I first saw the Fornax Cluster through my first telescope, a 4 inch f/9 on a wobbly mount bought for just over $100 from a camera shop. That was a surprisingly good deep-sky 'scope considering the small mirror. The f/9 setup gave great contrast which was important when I was living in the city back then and viewing from the subburbs.
Now for the big question. What is your next target?

Yes I had a close meeting with David a year or so before you, he gave me a signed copy of his book Colours of the Stars and took a few of my negs and processsed them for me - amplified and unsharp maksed'em
My next target..?...with the new 16803 chip on its way...maybe another but bigger galaxy cluster

..hard though, depends on so many things
