Hi all!
Here is my first observation & sketch of the comet 168P-Hergenrother from October 8th . It's easly found with an 90mm refractor at 101x from suburban area. The pseudonucleus is almost stelar and a short, like-fan tail visible, estimated mag. ~9-10, DC-9 and aprox. ~3'.

Fine sketch.
Did you use the Neodymium filter on the comet? I tried my filter for the first time on 186P but couldn't see any improvement.

Catalin,

Very nice sketch of the little traveler. It certainly is worth a look now that it is brighter.

Frank ;)

Tanks Jef and Frank!
Jef, I didn't use this time the neodymium filter, I mainly use it for planets and moon. For the DSO observations with the neodymium filter there is no major effect, only the sky becomes darker, which might help in moderate light-polluted areas.
Frank, yes ideed! At last, a telescopic comet after 6 months of "comet drought". :grin:

Yesterday I had the chance to see the comet in it's outburst. My view at Hergenrother 4 weeks ago was rather unsensationel. With my 32 cm Dob yesterday I saw a small coma, a straight plasma tail and an large broad elliptic dust tail. Using a high magnification (144x) I could detect a streamer, which may be generated by the outburst.
The bright star is SAO 91619, time was 18:30 UT.

Uwe, that's a lot of detail! Did you observe from a dark location? Did you use filters?

Very detailed sketch Uwe, a more "under the magnifier" observation of the comet.

Dear Jef & Catalin,

I observed from a rural site 15 km from Leipzug (500,000 inhabitants) away. I usually measure the sky darkness with a SQM and get values around 20,7 in the region of the comet. That is noting special.

I did no use a swan band filter this time.
