I have found Comet Hartley difficult to catch here in my light
polluted back yard in Vernon.But last night with my 15" scope the hunt
was over.I have sketched what I saw with my 7mm Nagler at 271X.I was
happy to see that I have captured it very closely to what Sky and
Telescope have published with there photo.I like it when I sketch
stuff that I have no previous image of and find out that I have
captured it very closely,it is very fulfilling.Here is a link to a
photo of it from Sky and Telescope.

Nice sketch! The comet was an easy target with my 8 inch dobson few nights ago under suburban skies so your light pollution levels must be very horrible! For me the comet only showed a brighter core and a little tail behind it, nothing as fine as your sketch shows! Good catch, nabbing a new comet is always rewarding - especially with the naked eye which is my favorite way of doing it.

I also got to see the comet, last night though. I also found it to be hard to find. Finally, I just skimmed by it using my 25MM ( yields 1 degree of field, which is sometimes really helpful ) , and once that happened it was over. I pushed the magnification to 200X, which felt a little awkward, because it was just so small/dim for being a naked eye comet! Anyway, I like your sketch, it closely resembles mine from last night.

John, glad you catched Hartley. It's no easy object in light polluted erea. In dark regions he's visible in binoculars. Keep following, because the comet is brightning. I hope to see another nice sketch in the future.

great sketch of the comet, i searched for it in binoculars from my light polluted suburban location but didn't see it, the lp here is horrible.

John,

Very nice sketch of the comet. :bow:
I spent the time two nights ago to track down this visitor.
Like you I was surprised at how dim it was. I think I'm spoiled with all the other bright comets in recent years.

Frank :)

John,
Nice rendering of this faint fuzzy--you captured its dim appearance nicely. I like that rhombus of stars that surround it. You can add to the observational quality of your drawing by including the date/time of the drawing in UTC, instrument and magnification used, FOV, and cardinal directions.

Jake is the first person I've heard call 103P/Hartley "easy" but he is an experienced DSO observer. However, Hartley is getting a little brighter now and the Moon is less of a factor. Still, it is a large diffuse object with very low surface brightness, so reported visual magnitude estimates are deceiving. It is in no way a naked eye object at this time.

The comet will be passing within 1° of the Double Cluster in Perseus this coming weekend--that might make it easier to find.

Elizabeth Warner of the Amateur Observers' Program is looking for sketches of 103P/Hartley in support of the EPOXI mission to Comet Hartley. I suggested she announce that here on CN. More info on AOP and EPOXI can be found here.

John,

An excellent observation of Comet Hartley (P/103). It appears to exhibit a diffuse nucleus and coma as well. The large aperture used must have made it easier. Thank you for sharing it with us all.
