Even though I am planning to mainly image with Luminance until I get more of an understanding how this ccd stuff works.
I couldn't resist trying out my color filters for the first time on this easy target.
I'm telling you this is whole lot of work. this image took 4 times longer then it would have with a DSLR....and a hell of alot more processing.
Data was collected over 4 brief sessions then you have to somehow combine all your data and hope it looks ok...hehehe
Flats, Bias and Dark frame calibrated with each channel
Not as sharp as I would have liked but its not easy imaging at 2500mm F10..well for me anyway.
LRGB 50:40:40:40 all 2x2 binning
5 minute exposures autoguided with internal guide chip.
I'm happy that I could atleast complete the image and it looks like the orion but not that thrilled for the amount of time I put into it.
Looks like I have plenty to work on....I have to keep reminding myself just small step Tony...lol
Hi Tony,
Very good, and thats a mighty setup you have there, The LX200R and that Camera the 11000 is top of the range, if thats your first picture of M42 with that setup, you will be up with the Pros. soon, I might suggest an F-3.3 Focal reducer (not expensive for SCTs) and then you would get the whole M42 in, but the setup you have now would be fantastic for ngc-1365 at a good position now for early evening imaging (although theres a moon waxing), anyway that Camera is as good as they come, so wishing you all the best.
Frank..I would say its more bad processing then anything
Jim,
yes the STL is a nice camera but it's far from top of the range...probably closer to bottom of the range specialy in QE sensativity...your paying more for the size of the chip being 35mm format
Regarding a focal reducer..its not that easy...if I used the Meade 6.3 fr I would loose more then half the image due to severe vignetting the 3.3 would be unuseable for these chips.
I tried the Lumicon FR which has a 80mm focal reducer at F7 last night....thats about as good as it gets in large format focal reducers and with that I still lost a lot FOV...below is a pic of the fov I lose with an 80mm Diameter FR..imagine what would be lost using a Meade 48mm fr.
You're off to a flying start and with the permanent set up in the observatory, you'll soon master the work flow process and there will be no looking back. Great 1st light image, especially at 2.5 metres.
for a first colour image that's a great start...keep 'em coming, its great to vicariously travel with you as you journey along this particular learning curve
Hi Tony,
Yes I should have realized the chip was that big, and a problem getting a wide FOV from SCTs, I have the same problem with my LX200-10" and the Canon EOS300D (smaller chip than your Camera) no focal reducer works that I have tried, im looking into the "William Optics" 0.8 Focal reducer made for their 66mm refractors to see if this is of any use on the SCT, seems you are in the same situation as I am, The SCT at prime focus only, and the ED80 or Lenses for the rest, The Meade/Celestron F-6.3 reducer works with the ED80 (some coma at the edges but not bad).
I would really like to see what you can do with Galaxy ngc-1365 and that setup, ive tried a prime focus using the LX200 + Canon but the noise beat me for a good picture, that ST-11000 should shine at this task.
