I've got barlows and powermates but no way to use them with the STL-11000, same as I use for my deep sky stuff. Everything there is set for a 3" opening and no way to mount even a 2" barlow in my set-up. I need to get a good web cam but haven't as yet. I used the STL-1100 as it is the only thing I have RGB filters for. I have an ST-7 but its got photometry filters not RGB. The 9 micron pixels are large for trying to work at pure prime focus. I don't recall the exposure. It was under 0.01" as my header says 0.00". That's a display rounding problem. The exact value is in the header if I want to dig for it. CCDSoft's default display of the header rounds to two decimal places. Still Mars hit an ADU count of 25000 which is about the max and still be linear with this AGB chip. I didn't lack for light!

Nice Jupiter. I've not even tried it. Maybe in a few months. It's rare for my seeing to be very good and since I can only snap one frame every 40 seconds or so getting even an RGB series with Jupiter's rotation rate means I gotta hit perfect seeing three times in three tries. Not likely to happen. Mar's turns slower giving me 4 tries each color before it rotated too much. Fortunately, the sharpest of the bunch was an L image so went LRGB to hide the problems with even the best color frames. Actually, I should have used the Guider chip as it's readout is very fast. Noise is high but with a bright planet that shouldn't be a problem. Then I could get dozens of shots a minute. Didn't think of it until now. Even isolating a small part of the STL-11000 results in a very long delay before readout begins. Doesn't really help much. Though moving it to the guide chip gets the image out of the zone of highest resolution. So maybe that wouldn't work well. The web cam is the cheapest route and I can use that with a barlow very easily.

I'm not much of a planetary shooter so hard for me to get all that interested!
