What CCD can see

[kochu]

It was a lousy night as usual ,last Saturday, at Jurong west. Very hazy, though not cloudy. I could hardly see Deneb, Well, my CCD camera could see some thing, when I tried out my Meade AR-6 Achro which I never had an opportunity to try out. It was in Sale Market for the last 4 or 5 years and no one bothered to look at it a second time even though it was offered for a throw away price.

Now I have decided to keep it as I see that for HA images CA is not a problem.

This is not a CCd standard image, but I think for the quality of the sky on last Saturday, it is not totally disappointing. At least , the stars are round for 15 minutes guiding with my 2X barlowed 350 mm FL Toy-scope.

Image details- Pelican Nebula- Scope Meade AR-6 Achro @ 1200 mm FL, Camera QSI 583, Filter 5 Nm Astrodon Ha,
Guide Camera Meade DSI, 6 subs of 15 minutes each,
Mount Atlas contolled by EQMOD, Imaged and processed using Maxim DL 5.
Now I am hopeful of getting good result on a decent night when I can atleast see stars visually .

Problem was always the weight of the Achro Unfortunately while I'd love the 6" of unobstructed aperture, the mounting requirements was also increased due to its weight. Otherwise I'd have bought it 6" of Achro shoudl outperform 3-4" of APO on DSOs any day.

Hi Kochu. Very nice attempt! Don't get to see photos from 6" achro so frequently. Thanks for sharing.
