Good start. I've never tried this before- how did you achieve focus and how long was that exposure?

Wow, amazing dimensionality to this photo! Going down to the Southern hemisphere for astronomy is like going through a secret door to another part of the celestial candy store.

Canon 60Da

Posted By Ivan Ong

IC434 and M45 are large objects and your NP101 should do it easily. ISO 1600 at 5min exposures from dark skies would do. Take at least 20x frames, use darks and flats. M1 is very small- you can try it with your C8, but it will need good tracking. Might want to use the reducer lens.

Good luck

I am looking at purchasing a 60Da. Anyone have experience with the unit on objects such as IC-434, M1, and M45?
I have a Televue 101, 102 and a Celestron 8 to try it with and reasonably dark skies.

Thanks

Pronto Vs Televue 60

Posted By Ivan Ong

Hi Margaret,
I have owned two TV 60s. They are optically great scopes, but the aperture is small and thus it's good mainly for quick views of the night sky. For birding they are great!

Orion Vixen 102FL Fluorite

I upgraded mine to a two speed Feathertouch. It tool them a while to machine the adapter but the end result looks nice and blends well with the original black Vixen tube. And yes, it is a huge difference to the original focuser.

Canon 60D

Depends on ambient temp. If hot (above 60F), maybe try ISO 800 for 3 min. If cold, you can go to ISO 1600. Also shoot in RAW. In RAW there is no need to worry about white balance. Don't forget dark and flat frames!
