Grus galaxies

Posted By Maurice Clark
Hi Inge,

The galaxies in Grus are some of my favourite objects for winter. (southern hemisphere! grin ) From Australia, most of them are visible in an 8" telescope.

You can see some pictures (film and CCD) on my website at: http://www.montgomerycollege.edu/faculty/~mclark/public_html/galaxy.htm

These are not the best images, but they will give you some idea of the appearence. I am currently re-processing all of my images (40 years worth!!!! 8O ) hopefully I can get them posted by the end of summer.

Cheers,

Maurice

LRGB question

Posted By Maurice Clark
Hi Paul,

Personally I choose to get all of each colour at the same time. ie I shoot all of the reds, then all of the greens then all of the blues.

The reason I do this is because the autoguider often gets confused when swapping filters, especially the blue because of the changing brightness of the guidestar in each filter.

Cheers,

Maurice

Annual Spellcheck reminder

Posted By Maurice Clark
Am I the only one who finds a long thread on spelling by Americans both amusing and colourful? grin

If only the spellchecker would give the correct spellings for so many words. wink

Hi all,

Emily Lakdawalla of the planetary society has a few of the latest images of Iapetus and a good discussion of them.

Hi all,

Seems like China's moon probe launch this morning went well.

Here is a BBC news report on it with video footage.
