Comet 168P Hergenrother

Posted By Roland Christen
Thanks guys. This was a very small guy, sorta lost in the field. Very fast moving which did not allow much time to capture the extent of the outer tail.

Images for October

Very Nice! I'm so glad someone is doing some imaging.
I was out last night, but after 2 hours the clouds rolled in - AGAIN - ARRRRG!

AP lens Fiberglass tube? Roland, your opinion?

Posted By Roland Christen
I have never tried a fiberglass tube, so I could not comment.

Some pix from Hawaii - the Big Island

Posted By Roland Christen
After a couple days the trade winds died down and some high clouds moved in. Got a nice set of rings around the first quarter Moon, with lots of color in the inner ring and one gigantic outer ring that did not fit quite into the 18mm len's field of view.

I know this picture does not look real, but indeed that is what it looked like. There were high ripply clouds and some lower stuff off the ocean that produced these multiple rings.

I am always curious as to what the colors look like on your monitors. Every time I look at what I have processed on a different monitor, I want to go back and re-process. (There is getting to be quite a queue for re-processing.)


Clear skies,

The only thing I see is that the RGB colors don't line up quite right from top to bottom. MaximDL can fix that.

Pier Without Fine Leveling Adjustment / Photograph

Posted By Roland Christen
You don't need to perfectly level the pier in order to get perfect polar alignment. It is "easier" to achieve polar alignment via drift alignment, but you can do it even if the pier is off by many degrees. If it is off N-S then there is no problem whatsoever since drift alignment is not affected at all. If it is tilted E or W, a drift alignment takes a bit more time since you will need to go back and forth a few times, but it will converge on the pole eventually.

All you need for perfect polar alignment is to be able to point the polar axis to true north, and that is possible regardless of tilt of the pier.

Photos from a musician living in Chile

Very nice composition, but used a bit of Photoshop trickery to get there.
