I had the good fortune of obtaining a new A/P 130 Gran Tourismo yesterday, and spent a few hours this morning configuring the dove plates & finder bracket. The finder bracket is mounted on the OTA, a bit inconvenient placement if ya ax me...but anyway...all i need now is a flattener and couple cam adaptors...of COURSE in the nick of time for SNOW/COLD/WINDY city late fall. Cain't wait to hook up some cams

Cheers

I just received an Apogee U 8300 I ordered recently, and plan to use it with my Canon
200F 2 lens. Precise parts made the correct lens to ccd adaptor, I made some losmandy
stuff...to make it easy to install robo set-up in the field, then stash in a case when done. Love the color of the Apogee

Thought ya'llz might get a kick out of this, I spent last night up by Ft. Sheridan playing with some toys

Believe it or not !! This was "first light" with my Mach 1 & 130 GT and using the Mach 1 was a piece of cake...outtta the box !

I had the 130 GT & flattener, SV 90 T, Canon 200 F2, FLI microline 8300, Starfish guider, Canon 5D mk2 ALLontop of the Mach 1 rings,plates, 50 mm finder, BUNCH of cords & cables HAD to be gettin close to 50 lbs of gear

took 3 18lb weights and the lil weight extension to balance with plenty room to spare

NO PROBLEM slewing, NO PROBLEM guiding, NO problem DAMPING, NO problem BALANCING

30 minute subframes PERFECT lil round stars with 5.4 mike pixels at 800+ mm focal length !!!

significant moment arm

BOY do those motors sound delightful during slew !!!

any of yas that ever "wonder" about the Mach 1 capabilities..... read this again and lookie at the pix

I tried out my FLI ML8300 last weekend and was SHOCKED at how cool this camera can run

The outdoor temp was about 55 F ( 12.7 C ) when I powered up, and it took this lil cam less than 5 minutes to drop down to -40 "only" a 52 degree delta

I have owned FLI max cams, IMG cams, Proline cams, Apogee Alta, many different SBIG, Starlight express

this is THE FIRST and ONLY time I've EVER seen a -40 set point achieved with "no sweat" AND power to spare !!!

I know... I know there are those who say ya don't "need" this kind of deep cooling for CCD imaging

to them I say BS the cooler the chip can run, the cleaner the FITS image is...less dark current !! PERIOD

Say what you will....but here's "the money" picture

NO darks or flats subtract..NO calibration 3 subs at 30 minutes in HA one sub 15 minutes A/P 130 GT/flattener ML8300 Baader 7nm HA

taken at Ft Sheridan 10 miles north of downtown Chicaga

This was a sum of 4 frames at 30 minutes each...down & dirty no calibration and I pushed it somewhat... I'll have to reprocess... have some noise issues to overcome

I took a few dark frames yesterday...my ML 8300 was in me closet to keep the surroundings dark
Upon power up the ambient temp was 20.1 C er 68.18 F the cam cooled down to -40 inside of 6 minutes errrr -40 in Celsius is also -40 in Fahrenheit

anyone out there have a CCD of ANY BRAND that can top this ? 8O

I doubt it
