Hi all, Got my off axis guider working last night with the 14" SCT at F10 pointed at the Box nebula, (NGC 6309) in Ophiuchus. It is 0.3' x0.3' Magnitude 10.8 . I did a quick search on the web, but couldn't find any deeper images. This one does show a faint hint of 2 extentions out at 2 and 8 O'clock. Would be interested to see what others can record.
This is only 9x6 minute exposures with Astro 40D at ISO 800.
I must add, although the off axis/flip mirror is a great concept the design leaves me a bit dissapointed. With only one grub screw holding the front and rear, where the camera attachment and 2" fitting to slip into the focuser are. Each of them have to be Very tight, otherwise the camera can fall off. Thankfully now I always have the camera with its strap secured to the rear of the scope. So If it falls, will only swing in mid-air without hitting anything. I am thinking of glueing the front and rear sections to the unit. This will mean I have to rotate the whole set-up to find a guide star.
Why such a well thought out instrument has to have just this small oversight. To have added 3 grub screws to the front and rear would elliminate any camera falling off.
You "Wolly" Lester. I had a closer inspection of this device and found 4 small grub screws, 2 at the front and 2 at the rear with pointed ends to be tightened with allen key and secure everything. So all is good. Camera cannot fall of if the device is secured properly as designed.
Great pic there
Ive done 1 hour on it with my 10 inch f5.6 and came up with this, got the faint extensions on it. I pushed the processing a fair bit Taken in sept 2010 with modded 350D, 10 minute subs
