narrowband IC2177

Hi all,

Been a while since I have posted any images. Too busy with grading and research. cwy

Here is one of IC 2177, AKA the Sealgull Nebula. 60 minutes each, Ha SII and OIII. SBIG STL 1001E and a 5" f/5 refractor. Processed with ESA palette. Still working on an HST palette version. (still too green!)

Cheers,

Maurice

comet 2009 p1 Garradd

Posted By Maurice Clark
Hi all,

It might not be quite the same scale as Lovejoy has been for the southern hemisphere, but comet 2009p1 Garradd is putting on a nice show in the early morning now.

Observing it this morning at around 6.30, it was easily visible in binoculars and showed a short, faint tail in the telescope. Total magnitude was around 6.5. The image below was taken with my 5" Apogee refractor and STL-1001E CCD. Combination of 5, 3 minute subframes with red, green and blue filters.

Cheers

DSLR Modification options

Posted By Maurice Clark
Hi all,

I have a student who is looking at getting a DSLR and having it modified for astro use. He was just asking me which modification is better... Baader or full-spectrum. He would be wanting to use it for normal photography, but mainly for astro.

Anyone have any thoughts on this?

Thanks

Maurice

Posted By Maurice Clark
Hi All,

Emily Lakdawalla over at the Planetary Society has posted a link to a series of photos of used Soyuz spacecraft. Quite interesting. Only one problem........ the discussion is all in Russian! cwy Still, the photos are interesting. The link is below.

Geostationary Satellites

Posted By Maurice Clark
Hi All,

I ahd an unusual observation a couple of nights ago. I was checking out M42 for fun with my 18" dob, when I noticed 3 objects moving across the field. I quickly realised that these were goestationary satellites as I have often had images of this region ruined by these things!

What really struck me though were 2 things. Firstly the 3 satellites were in a nice straight row.

The second was how the brain worked. I stopped moving the telescope to keep them in view, but even though I KNEW that it was M42 that was moving across the field, the brain kept trying to tell me to move the telescope to keep the SATELLITES in view!!!! 8O

It was fun watching. The were about 9th - 10th magnitude.

Anyong else seen this?

Regards,

Maurice

Another one quits

Posted By Maurice Clark
Hi All,

I see that Perry has finally realised he was not getting anywhere and pulled out of the race, backing Gingrich, calling him a "conservative visionary". 8O

Wonder if this will make any difference in South Carolina this weekend.

Hi all,

The Sun has just had a fairly large coronal mass ejection that is heading our way. According to SpaceWeather.com, there is a chance of aurora on Saturday night.
