LCROSS from yestarday with a 4" refractor

[paulobao]

Hi,

yestarday I caught LCROSS with my Tak FS102 (a 42 refractor) +
QSI532WS-M1 at -20ºC.
I live in a LP city in portugal.

here the pics and gifs (9x60s and 4x180s):

EXCELLENT.. Way to go Paulo. !!!

Very cool, paulobao!

[Derek C Breit]

Very Nice...

Now I want to try for it from Morgan Hill, CA..
-121.702767, 37.113283, 282m

I can't even remember the exact name to enter into Horizons..

Note is someone decides to do it for me, which is not absolutely necessary,
I need RA and DEC "of date", not J2000.0..

But the name would be helpful..

I will try it tonight or tomorrow night..

Hi Derek,
of course you can use Lick Observatory's MPC code 662 which will get you
real close.!

other codes are here.

good luck tonight.

Thanks..

I have entered my position.. That I know how to do..

I hope the target is LCROSS, because that is what is entered..

All my columns are set..

Now to press enter..

We shall see what happens..

:-))

Hmmm..

This says I have a 70 degree pass of LCROSS...

I thought the Northern Hemisphere was not supposed to have good viewing of
this object???

Thanks,

of course is a 4" refractotr not a 42...I wish :-).

I will try it again, if the weather permits so (now is realy nasty!).

Regards,

paulo

Grande foto Paulo!!
Muitos Parabéns pelo feito!!

Because it was expected that sky washout from the near full moon would
wash out an expected 15-16 mag object. Although no one has done
photometry on their Centaur images, clearly, the spacecraft must be
brighter than mag 15-16. The expected result - object not capable of
being imaged because of Moon light interference - is not being
experienced by reporting imagers. In otherwords, a happy, fortitous
and unexpected departure from prediction. It terms of altitude,
LCROSS is still well-placed for northern hemisphere observers. - Clear

I haven't yet blinked the images I made, but I am pretty sure I was not
able to see LCROSS..

Well, in fact I did some photometry of it (from the 20090702 data).
I used 2 different software packages and the results are the same at
mag 16.

here the pictures:

- astrometrica (forget the RA/Dec coordinates): http://wrunch.com/images/klz1246792409b.jpg
- FOTODIF (using a calibration star + a reference star of known
magnitude): http://wrunch.com/images/jdv1246792534c.gif

I concur, yet I need to reduce all my data. Got more imagery last night too
even with the bright moon.
When I reported my first observations last monday, LCROSS had passed by a
mag 16.2 star and was clearly fainter hence my estimate of its brightness.
I'm using a Luminence filter for the CCD images which is fine for doing
differential photometry. To do it properly I'd have to use a V or other
photometric filters, which unfortunately are not in the remote filterwheel.
So the magnitude is an approximation but obviously close enough.
