M45 imaged 10-11-09


Recommended Posts

I tried M45 as a mosaic trial target but due to clouds and problems with guiding was unable to get a second image but I thought that the new mod to my 400D seemed to help with the nebulosity WO 90 13 x 5 min subs unguided ISO 800 captured and processed with Nebulosity and PS

It would have been a great mosaic if this one is anything to go by :) And 5 mins unguided, nice going :rolleyes:

The nebulosity around this cluster is reflective, rather than an emission type. As such, the mod to your camera probably wont show much difference on this type of target, but just wait till you try it on the Horsehead, or M42 which are rich in hydrogen emissions which will now be picked up by your cameras chip.

Thanks for sharing this one with us, I hope you get to complete the mosaic. Looks like you have nice dark skies too?

Hi All Thanks for the feedback I just started imaging with the 400D un-modded last year and found it a good foundation for this year with the mod I also started to use Nebulosity to focus and capture images on the laptop and I think that has helped me also.Hope to get the guiding going next time and maybe increase the subs exposures.
