  Summary: Comet 17P/Holmes shocked astronomers on Oct. 24, 2007, with a spectacular eruption. In less than 24 hours, the 17th magnitude comet brightened by a factor of nearly a million, becoming a naked-eye object in the evening sky. Look for a golden 2.5th magnitude fuzzball in the constellation Perseus after sunset. [sky map] [ephemeris] [3D orbit]

Comet Holmes in the UV wavelength shows both Cyanogen emission and reflections from the sun in that narrow band. It is also a useful way to improve the contrast against the background stars to see more details on the outer areas of the comet. These images were taken through a Celestron Onyx80EDF telescope with a SBIG ST2000 camera and Baader 2" UV filter. Exposures were 5x300s and guiding was done with MetaGuide.

Comet 17P/Holmes located near the Mirphak (brigth star on the left). On the image are nebulas NGC 1491 and Sh-2-205 (to the right) and open cluster NGC 1528 (close to right margin),too. This is 48-min exposure (12x4 minute exp.) by Canon 20Da with 135mm camera lens at f/3.5 (ISO 1600 ASA).

This is the deepest shot of any comet I have ever taken with my 12.5" newtonian. Clearly seen here are delicate internal rays comming from the nuclear regions, a bright jet and a brilliant sunshine yellow core. The outer green envelope recorded as a stunning emerald color. ST10XME, 120 minutes RGB

Comet Holmes is getting Huge. In this Nov2/07 image you can see how the solar wind is forming the Coma. Rays of comet dust seem to expand out from the core. I took the photo with a 8 inch Celestron and an Olympus digital camera.

The comet is growing and growing. My estimation is about 12 arcmin. I think on Sunday the comet has half moon diameter. Very good to see with the naked eye.

Now the size and the brightness of the comet make it a veritable urban comet. The comet structure is visible just with the naked eyes. Also, it was visible in same photo field with Moon in conjunction with Mars. Just without a tail, this comet is a fantastic one!

This long exposure (1,200 seconds) was need to capture the faint but well defined streamers of the comet Holmes. This negative view aids to see better the tails at the left of the comet in this image. Canon EOS 350D modified with a Nikkor IF-ED 300mm, f/2,8 lens plus a TC-301 2x teleconverter.

Amazing Comet 17/P Holmes and Iridium flare from Santiago de Compostela (Galiza-Spain). Both shots were taken with a compact digital camera (Canon PowersShot S400 4Mp)from my roof. Wide angle has 15s exposure and close up shot (13s) was taken through a 7X50 binoculars.

The comet continues to grow larger and larger each day. It looked huge through my 14.5" Starmaster and a 12mm Nagler. I took this image through the Starmaster with a Canon 30D.

This is a 4x mosaic with each frame of the mosaic containing 15x40 second subframes. Turned negative to show the complex tail structure
