This one: http://www.ceravolo.com/astrograph.html Mine is customized with Invar rods - if I don't change the camera I only have to refocus seasonally!
Presenting the Leo Triplets in monochrome. The seeing condition was poor and surface gusts didn't help. This is 60 second exposure using Stack Pro™ for a stacked four to total 240 seconds. Four such runs were taken and these stacked on the PC for a total of 16 minutes. Under better conditions, will frame the galaxies properly as I had used a star to center the FoV. Nice feature of Maxim D/L is ability to plate solve, calibrate the CCD FoV and then one can mouse-click on the taken image where to move the scope and better frame the shot. Tim
