M8 and M20 in 69 seconds. That's all the clouds would allow me. Just 1 frame, no darks, no flats, no guiding, no time, no nothing. ED80 running at F 4.4, Orion focal reducer, full spectrum Nikon D70s at ISO 1600, Baader UV/IR cut filter.
It would have been nice to stack a couple of hundred of these...
LOL, I think this year has been the cloudiest for all of Australia for a while. It's not uncommon for Mackay to go without sky for 9 months, but this year it seems everyone is complaining about it. Unseasonably warm here too, even for the brief periods when it is clear.
Yeah Jo getting into the micro data game. Well, basically this is "one sub" that would normally be stacked with a hundred others weather permitting. I thought it contained pretty good data though for a single sub so I put it up. Often I will see very little on 1 sub.
HEQ5 pro goto Dunk. With good PA I can get anywhere from 30 - 90 seconds unguided depending on load etc. The F4.4 reduced ED80 only has 350mm focal length so it's very forgiving of drive errors.
very nice kevin. Why do you need to use a uv/IR filter? If you were in darker skies could you go down to 800 iso? I have LRGB filters,could i use them with my canon 1000d camera? Can you use visual filter oIII etc to take images?
Thanks Mark. The UV/IR filter is needed as the Nikon contains no filter at all. It's not astro modified, it's full spectrum modified. Without it, the stars would bloat and the field would look hazy.
Actually I forgot to reset the ISO after using the Bahtinov mask for focusing otherwise I would probably have used a lower ISO.
If you have 48mm (2") LRGB filters you could try them with the 1000D. LRGB with a colour camera is not the most efficient way to shoot pics, though it can be done. Same for the visual OIII. Depending on make, some visual OIII filters let through Ha as well. That would give a kind of Bi-Colour image. Speed would suffer. OIII are usually very narrow and you would be looking at very long exposure times, giving rise to camera noise etc.
Just 1 frame, no darks, no flats, no guiding, no time, no nothing.
