Astrobug

When they will sell a big mono cmos (full frame or more) you will see more cmos pictures on astrobin with high end setups. Also experience how to proces images is also important. Most 1600mm user are still in the early (like me) learning curve.

Good mirrors are not cheap. It is all hand crafted. If you go for the ONCT from TS, ask for a spider upgrade. They have 2nd mirror holder with a push/pull system. They are much better in keeping the collimation. It will increase the price but you will not regret it later on. I miss one important feature on all these scopes, none of them cover the edge of the mirror.

Premium price

They have some high end scopes also. But somewhere elke on the website.

You have 2 more options: Skyvision.fr started a new range of newton scopes (8 & 10 inch). I think the mirrors are coming from Frank Griere (mirro sphere). Jtwastronomy is also selling newtons but I did not see any of them.

I use the sesto senso and happy with it. No issue to get it work with apt. Easy to change it from one scope to the other scope.

Coming from a ts 80 triplet to an esprit 100 it is a real improvement. The stars are round in all the corners of the 1600mm. For me the esprit 100 is a keeper. Also the focuser is way better. No tilt anymore when using the locking mechanism. Then some argue the tak is better but for an aps size sensor and 4 times the price (with accs) it is another story.

Well done, this one is on my list.

Thx! The OAG was easy to use. Maybe it is because i'm working at F5. Not sure about slower systems. It is the one from ZWO, it works out of the box with my cam. With the guiding scope there was some flexure visible on the stars. The small pixels of the 1600MM with 1m FL gives not much tolerance.

I added 60 min of HAlpha.

Well done.
