hi this is Graham from Jenham's Astro. Here in the UK over the last week
we've had some high pressure as you can see from this barograph trace so once
the full moon's got out of the way I've taken the opportunity to try and do some
imaging. Now there's an object in the night sky the moment called comet ATLAS
now this was supposed to be the next big thing the next bright comet potentially
a naked-eye comet later in the year but from all accounts the object is fading
now and it's possibly possible that the nucleus is disintegrated so I'm going to
try and take the opportunity to capture a comet and
see what I can record with my William optics GT 81. Now looking on Stellarium
before setting up I notice that there's another comet in the same part of the
night sky which is comet pan-starrs so in fact this video is me trying to
capture two comets in one night
okay so that's it two comments in one night the processing to do tomorrow
we'll see how the images compare okay so I taken 30 one-minute frames and I've
put them through deep-sky stacker and I've chosen to use the comet mode which
I always find a little bit fiddly but after getting used to it again you can
get a good result so this is the image of Comet Atlas it shows a nice tail the
central nucleus of the comet though it's quite diffuse and I guess that's
indicative of the nucleus breaking up
compare that with pan-starrs is lower in the sky for me bit murkier looking in
that direction at that height a brighter nucleus although the actual object is
fainter than atlas but a more concentrated emission of light probably
a little bit easier therefore to capture but no tail and then comparing the two
pretty happy to have captured two comets so they were six degrees apart in
the night sky very different the top one is no longer going to be the next big
thing! So I hope it's been useful thanks for watching if you liked videos like this
one then please subscribe to Jenham's Astro and talk to you soon.
