ASTRO: Adding more frames to my Holmes scale image
I had a few sucker holes open just long enough to get shots of Holmes
though clouds dimmed it somewhat. I now calculate its diameter as about 1.6 million miles, nearly twice the sun's diameter and it is still growing. It's now too big for my system. If centered the edges are completely out of frame, even in the corners. So I decided to concentrate on the tail area on the 18th rather than center it. Alpha Persei causes the mess at the bottom right. It is just out of frame. This was taken the night before closest approach. It snowed that night, then rained. Winter just can't make up its mind if it is coming or not. I see little gas that was seen earlier. No blue tail showed at all though the night wasn't as good and it is fading. Though the haze of the 18th the comet wasn't bright even in binoculars and was lost naked eye to the moon lighting up the foggy haze. This image is at 4" per pixel, half of what I used before as the image was just getting too big at 2" per pixel. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

ASTRO: Adding more frames to my Holmes scale image
Yep, this one is getting bigger and bigger. Last time I imaged it I decided
to use a 300mm lens to get some of the nice star background in Perseus. Stefan "Rick Johnson" schrieb im Newsbeitrag ...

Rick, astonishing images as usual from you.
I'm taking the liberty to use your pics to show the evolution of 17/P at our next lecture at our astronomy club, I hope this will not bother you. I'm citing the Author, of course. Keep up the good job and clear skies, -------- Beta Persei 45° 35' N 08° 51' E remove "_nospam" to reply "Rick Johnson" ha scritto nel messaggio ...

... ........ Alpha Persei causes the mess at the bottom right....... Rick, Actually I think the bright star adds some "character" to the image! This certainly is a neat presentation of how Holmes has evolved. George N |
