This is the Intes-Micro M603 6 inch Maksutov. This premium, moving-mirror Mak with lots of focus travel sells new for more than $1000 and has received rave reviews.
This scope is three years old. The secondary mirror is well-collimated. Primary mirror collimation may need tweaking. The following conditions should be noted:
If you look closely, you can see that the OTA has a small amount of dust in it (far too little to impact optical performance). Some of the dust specks look like OTA paint that probably entered when I loosened several of the mount rail screws in an attempt to remove the rail to have it measured for a set of dovetail clamps.
One of the mount rail screws at the very front of the OTA has a damaged head. The screw is still firmly in place.
The two mount rail screws at the very back of the OTA no longer screw firmly into the OTA. The mount rail is held firmly in place by the seven screws that do firmly attach, however, and I have had no problems with stability of the scope on my altaz mount.
The above conditions have had no effect on my use of the scope, and the scope is in otherwise excellent optical and mechanical condition. I am selling because I need more aperture for deep-sky, and I have purchased a larger scope. The package includes:
Caps for front and back of scope and finder
I am new at astromart, but I have an excellent reputation elsewhere. I have reduced the price to $500 firm + $20 FedEx shipping. I have more pictures available on request. Thank you.
