Hi,
I like wide field and do not like spikes.

I have a 5" APO refractor. I like that telescope very much. For the money I paid for that telescope I could had bought a 12" RC telescope, then I get a f/8 or with reducer f/6.3 system. The field or image circle about 55 mm. Something you can not use today, maybe in future with medium format sensors. My 5" telescope too have a big image circle, maybe 55 mm, but only 910 mm focallength and a slow f/7.

If I buy a new telescope in future it will be either a 6" APO refractor or a 10" RC telescope. But I live in a city with high light pollution so I use my not so heavy Star Adventurer and camera lenses more, that equipment I easy can take with me out to darker places.

Small telescope without spikes or big telescope with spikes. I think Mak-Newt normally have a limited image circle and can get uggly reflections in the correction lens.

I'm not made of money and I always buy used equipment.

This was out of topic and I stop here.
