If you wanna help a bit the science research you could think to install the Boinc client.
In this way you could join different research programs in a lot of fields (for example astronomy, physic, medicine, biology etc..).
Boinc use a bit of your PC's processors power (based on your settings) to elaboborate some data package, sent to you by the institute/university to help their research that needs lot of elaboration powers. In this way (distribuited calculation) every single user help a bit.
My explanation surely isn't so good (also sorry for my not so fluent english ) but you could find a lot of informations searching with google. Anyway this is the homepage of Boinc.
The list of project is here.

If you decide to join some project, in the team section you could join us searchin for the AstroAmateur@home team.
Thanks.

Hi Res Ceres (Minor Planet / Asteroid)

Saturday, March 28, 2009

Link

I was inspired by Fabio Plocostomos and Chris Go's work on Ceres at high res and decided to go for it myself near opposition or good seeing. So that single 2 day break in rain and clouds a week ago yielded some good Venus and Saturn images and also this great view of Ceres.

I had a hard time finding some good ephemeris data for angular size so calculated it myself as follows:

http://en.wikipedia.org/wiki/Angular_diameter

δ

= d / D, where

δ

is the angular size, d is visual diameter and D is the distance to the object.

So using the WRONG units I get:

1.64AU distance to Ceres and 950km diameter of Ceres gives 0.798".

I hope to not have overexposed the object which would have caused bloat or bloom in the data. I stretched in post processing and resized to 200%

Enjoy!

Titan Transit Teaser 20090224

Tuesday, February 24, 2009

Observation logs

I think there's a name for titles like that, but at 25*F and early in the AM my brain's not so straight.

Bad seeing too.. looked like the whole continental US had bad jetstream. I hope someone west of here got better as it was fairly low on the horizon here.

I forgot about the time delay in stellarium but that was OK as I overslept a bit anyway. Most of the frames are washed out by the trees but you can make out the shadow in the final 3 or so frames. I also caught Dione in a few frames riding the upper left ring, long before it's transit. So no quad transit, but I was able to get something and that still counts! Lucky me, the sky was clear.

*My* 1st light with the new setup - M81/M82

Friday, February 06, 2009

Begin:	2009-02-04 um 20:08:01-05:00
End:	2009-02-04 um 23:59:00-05:00

Weather:	S:? T: 3?/5 Clear, cold and WINDY!
Equipment:	Optics: Meade LXD55 Mount: CGE mount on JMI Wheely Bars Focusing Aid: STI focuser Shutter control: Hap Griffin long exposure cable Software: MaximDL Operating System: WinXP Lenovo T43 driven via RDP from inside the house
Comments:	MY 1st light of the Meade LXD55 and CGE!!! What a pleasure to wheel the whole rig out of the garage into the driveway! Used my Celestron knowledge to get a rough align and was able to get fair results of 90sec+ exposures. At f/5 and ISO800 there is a LOT of LP Setup on M81 / M82 to get lots of subs, staying warm inside now as the outside temps dropped into the upper 20's Align was in the double digit of minutes error after a 2x iterative align. No PEC, no polar scope, no guiding, no drift align.

"Near" the Apollo 11 Landing Site

Sunday, February 01, 2009

I think the forecast for the night was better than it actually was by a long shot. After checking the collimation I would have guessed it was 5-6/10, but looking at the focus/collimation test on Castor (great double BTW), it was a mere 4/10. I setup to grab Venus and the moon before a longish night on Saturn. One of my music buddies, John, suggested that the Apollo 11 landing site was in prime view and that I should try imaging it. I did and was happy to have a fresh target even though the seeing was poor, thanks John!

First a clean image:

Then one marked for reference:

I actually found the google moon maps useful, have a look and see if I got it or not!

2008 Solary System Review

Saturday, January 24, 2009

I recall seeing a flurry of these 'composite' shots last year but not so many this year. I was keen on getting better Icy Giants and went after Uranus and Neptune with as much precision as I could. In all my hasty planning, I let Pluto slip away. It's still a planet in my book so I'll have to give it just desserts next year! I had some photos of the sun shining on the trees in my front yard and thought I'd add that to round it out, but you might find those on my homepage just as easily and I thought it would mess with the 'flow' of the sequence.

Hope you enjoy! Looking forward to 2009!

perigee Moon

Sunday, January 11, 2009

Perigee Moon of 2009! Tonight will be the biggest moon of 2009! 14% wider and 30% brighter than a normal moon.

This is a image I got last year (12/12/08) of the perigee Moon. I took this with my Meade Etx-125.
