M33 - First Light w/ST2000XM

Here's my first attempt at imaging M33. I used the ST2000XM with my
Takahashi TSA102/G-11. The image is a stack of 10 lum shots @ 120s ea.

What a cool shot. The FOV is really nice and the detail is certain there.

Looks a lot like my first film shot of it back in about 1963. With
curves you should be able to cure the burned in center. More time to
the exposures using the guider chip should get rid of much of the grain
though galaxies and nebula nearly always fade to noise at the edges I'm
finding. Note Stefan's comment the other day that his G-11 guides best
using a 2x guiding speed not the 0.5x default value. So some
experimenting may be necessary when setting that up.

Nice picture Scott. Camera and scope suit each other well, stars look very
good even at the edge of the field.

Cool image Scott!

Is the TSA 102 a new model? A few years ago at Stellafane the owner of
Optical Guidance Systems set up next to me with his personal scope (not an
OGS!!) - it was a 102mm Tak refractor on a Tak mount. Around 11pm his kids
starting acting up so he left the scope to me for the rest of the night. It
provided some really impressive wide-field views.

George,

I believe the TSA 102 designed has been in the retail market for a little
over a year. It is the replacement for the venerable Takahashi FS102. The
TSA 102 is a triplet design similar to the TOA series, whereas the FS series
were doublets. Specs are he

Ah, yes..... The scope I had the pleasure to use for a night was a FS102.
Great little scope! It was particularly nice on M-4 and M-22. The new
triplet must be even nicer. The same guy the year before had two scopes: one
of his own 12.5 RC's and a Tak 6-inch refractor.
