Yep, the 67 flatteners that came with my 155 f/7 and 180 f/7 create a lovely 100mm image circle with minimum vignetting and great sharpness across the entire circle. A large array for that full covera

The telescope was Roland's fabulous 254mm f/14.5 mak cassegrain. Perfect collimation and superb if not borderline perfect optics. Imagine having a 9-inch refractor to look through. 600X? No problemo.

My first ever digital imaging using the Mak Mars attacker. Shocked to see I actually picked up the largest known volcano in the solar system from my backyard. - j

Lovely shot. The only problems I have had with 1 hour subs is temp change, resulting in focus change during the long sub-exposures or running into the dreaded "mount flip" before the exposure is compl

I don't think you need to do full sky modeling. Model on the area you wish to image from the POD, and run with that. Seems simpler.

Will you have someone nearby to assist with troubleshooting and repairs? No such thing as autonomous. If it can fail, it will. Speaking from experience. jg

Interestingly, the MaximDL camera control window shows 515 of 600 sec.

I would expect the Mach 2 would carry your 180, but moment arm vibrations at the eyepiece is why folks recommend the beefer 1100 bearings. The 1100 also breaks into very tidy lightweight components fo

My ap 180 f7 rides on my 1100 and losmandy hd tripod no problem. 3, 18lb weights, plus rings, saddle, dovetail plates, finder, diagonal. 20 ethos, no problem. I like the losmandy hd for the flexibilit

Just noting that there is vertical banding visible in the image. (and I realize this is just a test image). Might be worth looking into when you want to take a "pretty picture". ;-) jg

Mo, You might be surprised to learn you can use a small guide scope and guider array where it becomes easy to find a guide star. Just say'n. J Sent via the Samsung Galaxy Note9, an AT&T 5G Evolution c

I totally agree with Bill Long and Roland. For many years I used the AP 180 F/7 EDF on my 1200 mount. By the time I added all of the accessories for imaging, including guidescope, I found the 1200 to

Wow, that looks great, although a little low for a refractor. J Sent via the Samsung Galaxy Note9, an AT&T 5G Evolution capable smartphone

It's all about the moment arm. Long tube, weight on each end. The Mach 2 will support the weight. But it may have the Jello effect because of the long moment arm. Sent via the Samsung Galaxy Note9, an
