Eta Carina

I had my first chance to image last night..full moon but who cares..was just happy to be imaging....it's been so long.

Image taken at my house Brisbane with the 20DA on the C11 with baeder UHC-2 filter.

I was also imaging through the lumicon giant easy guider that I find useless to guide with but I like the huge 80mm focal reducer which can be positioned in different area's altering the Focal ratio..anything between F4 - F7.5....so I will continue to use it for imaging and forget about guiding with it.

Total exposure time 12 minutes at approx F6 at focal length 1700mm

12 x 60 second Unguided exposure ISO 800
24 Bias frames
8 Dark frames
No Flats
All combined in ImagesPlus.

No noise reduction used.

Software used
DSLR Focus, Images Plus and PhotoshopCS

Pretty happy with the image even though there are small star trails due to my pathetic polar alignment.

Wow Tony - that is fantastic - well done for giving it a go with the very bright full Moon. Boy, did you succeed; a really great image of a wonderful region of our delightful Southern Skies.

Cheers

Dennis

Thats a terrefic image, great to see a fellow astroimager using the baader UHCS filter, its great for bringing out red emission nebulae in light or moon affected skies
Very good for just 60 sec subexposures too. I should try 60 sec shots on nights where wind and so on causes me guide errors over longer exposures.

Hi again Striker
Hope you dont mind, but I had a play in Iris with your image, using the gamma select function to increase the enhancement of the faint outer detail. I also manually "flat fielded" it by drawing a circle over the inner 2/3 of the image, then darkening it slightly so that when I used the gamma select then stretching it the illumination would remain even. The original image thus has quite a lot of detail. What do you think

You can play around with any of my Images Scott..no problem.

I can see slightly more detail i just hate the JPG compression artifacts.

I did some flats today and have have redone the image with Bias, Flats and darks....I can send you larger Jpeg to play with you if you like.

Awsome stuff Tony, you have captured a heap of detail in that image

Pathetic polar alignment, you wanna see my recent attempt at getting aligned

Can't wait for you to image it again without moonlight and spot on p/a.
