I do... ;) albeit in miniature... still allot of fun though...
ETA: lots of good plans, formulas, et al. on the interwebs if you're serious about building one.
And teasing the holy heck outta my dogs… sit on the steps outside the patio door, looking through the window and flipping their tails back and forth, while the dogs go absolutely bonkers…😖
Interesting note re. the illumination… I was also rather disappointed with the illumination in the DFP 1.5 -15, definitely not as bright as expected for illumination in the 2nd focal plane. Was expecting it to be at least as bright as my Mk 6 1-6; it is not ☹️.
