Simeis 147 ( Sh2-240)

H Marciej,
A truly difficult object, dim, wide field and lots of filamentary detail. I think you have done an excellent job here!, Dave

Linear, Encke, ISON, Lovejoy Oct 27, 2013

Posted By Dave Erickson

Attached are four taken the morning of November 3 within hours of each other. Each is a single 6min Exposure using a Sloan Yellow Filter and the 4.5" F/4 astrograph. Image scale is preserved. Linear is 8th mag, Encke is 7.8mag, ISON is 8mag and Lovejoy is 10th mag...
I think its amazing there are (4) reasonably bright comets appearing so close to each other in our sky.

Left to right comets: Linear...Encke...ISON...Lovejoy

Same night I viewed ISON in 10X70 Binoculars...

Lovejoy sketch

Posted By Dave Erickson

Nice sketch! Lovejoy is considerably higher in the sky than ISON as well...

Best regards,

Hi Russ,
Good comments the only thing from a setup perspective I can add to Floyd and Roland is that it looks like there might in addition be slight field rotation from polar alignment, was the guider in the upper right of the image. Also a couple of dust motes that a flat field at that rotational azimuth will take out?

All of that aside, very nice first light images! Congratulations on realizing your 40 year dream!! 8) Looks like a great imaging setup. Imaging remote for the first time is a combination of terror, joy and relief. Seeing the first images come down is an amazing experience, like the first view through a telescope that hooked you on the hobby. After more than two years of remote imaging I still get a thrill every time... Again congratulations, and keep those images coming...

Best Dave

Well....... Here is an image from SOHO a few hours ago the tail is reported as dimmer than earlier but is about 9 degrees. Thats Antaries in the lower left. Got Paul's opinion anyone else venture a guess??? Like Paul, I am not as optemistic as I was... :S

Here is another SOHO Image from this morning showing ISON and Tail after its solar encounter. Will we see a comet? Sure looks like something made it albeit a lot worse for wear... 8O

Here is a link to the SOHO site...
