Comet C/2010 U3 Boattini - at last!

Recommended Posts

During February I have made three attempts to observe C/2010 U3 Boattini. The first attempt was a fail. The second attempt left me with two possible outcomes but I had a feeling for the "small fuzzy blob" that I had found but could not re-find!

Finally, I confirmed my sighting last night and I was very satisfied when I did :)

I use Sky Safari to control my push-to dobsonian and I am not convinced that the location in the app is spot-on. This comet has been a challenge to get into the field of view which is not usally the case with comets & Sky Safari?

Either way, if you are looking for this comet then I can confirm "IT IS THERE"!


My observation notes from 13 Feb 2018

C/2010 U3 (Boattini) – I set about searching for the mag 15 comet. I centered up the push-to with the ethos13 (x150) inserted and then moved to ethos10 (x200). I could not find the comet for definite. There were two possible glimpses (1) I did spot a small fuzzy blob near a patch of stars but failed to re-find it (it did not tally with the Sky Safari location but it was close) (2) I thought I saw a tail cutting through the fov (this was the same experience that I had on Sunday when searching for the same object) but the scale of the tail seemed too long and wide to be true. I will keep trying but could probably do with some better conditions. :( 


My observation notes 20 Feb 2018

C/2010 U3 Boattini – I can finally say that I have seen this comet! I managed to confirm the sighting from last week, it had only moved a slight amount and I confirmed this morning that it is very slow moving comet. In the E10 it was a faint small fuzzy patch below a small group of stars (which I recognized from last week). In the E8 (x250) it was an improved fuzzy patch (but still hard work) and finally in the E6 (x348) I got glimpses of a “dot” core but it was very hard to focus as this was too much magnification for the conditions. Still, I am pleased to have finally tied it down!


Here is the expected path for C/2010 U3 Boattini...

Congratulations of finding the comet. Sounds like even a 20" dob struggled with it, so little point in me going out with the 6SE.....lol  Do you know its due to brighten at all?

We measured the magnitude last night from the Northolt Branch Observatory. It was mag +17.5

Shame, I can't get the obs'y scope on it at that elevation and it looks like it's going to lurk around the pole for a while.

      A spectrum of Comet 46P (Wirtanen) with the ALPY600. 

      The raw spectrum image before sky background subtraction. Note as well as the comet spectrum, the bright Na D line from local light pollution and other auroral lines from natural airglow
      The coma extended beyond the length of the slit so a separate sky spectrum was recorded and subtracted

      The Spectrum of the bright central region is dominated by the scattered light from the sun while the spectrum of the extended coma is mainly emission from excited molecules such as CN (The very bright line in the UV), C3,  C2 (The Swan bands which give the coma its blue green colour) and NH2
      By removing the emission component from the spectrum of the central region and dividing it by the spectrum of a sunlike star recorded the same evening, the reflectance spectrum of the dust can be extracted

      I'm still dizzy after processing this one for each LRGB filter.
      Comet 21P meets open cluster M37 in the night/morning of 10/11 September, at perihelion.
      This is a combination of 60s x 30 x 4 subs, taken through the SW130PDS with an ASI1600MMC.
      No deconvolution applied, only noise reduction. About the remaining noise?! ... yes, please. Unfortunately the light pollution at home didn't let me record more.
      Thanks for watching and clear skies!

      500 x 4 second frames at 20 fps. 33 minutes timelapse. Taken tonight with an evolution 925 at F/6.3 and an altair astro GPCAM3 385c camera. Mount decided to be a dick towards the end ?

      I just tried to see the moving of this object. I made 20 frames with my Huawei P10 smartphone, with the monochrome camera. My star tracking is not so sharp, I have alt-az mount, I used only 10 sec expositions at ISO 1600. The shots was taken in every 10-12 minutes in this time intervall: 00:16-03:53am 2018. 08.16. Celestron Nexstar 8 SE, 25mm plössl eyepiece (magnification 80x). Of course I used a good adapter too. Frames has added with Gif maker pro mobile application.
