Subject: Re: [Astro_IIDC] Help-12,5 days Moon Disk needed to identify a moving object (Geosync Satellite?)
Hi Alberto;
Interesting images and thanks for sharing.
I'd love to help, but it was overcast / windy / rainy during that period, so I don't have any lunar disk images to share.
On a side note, you can save about 50% disk space if you compress the movies for archiving. You can use Apple's built in .zip compression (i.e. from the finder, control click on a a movie and them choose "Create Archive of " which makes a .zip file of it) or perhaps Stuffit or some other utility.
I use Stuffit because it does a better job of compression (saving 10 to 20 % more than Apple's .zip) and also allows me to browse or extract single items in .sit archives too. Then I archive the files onto DVD-R disks (I have about 70 gigabytes of backed up movies). I can't wait until the blu-ray drives come down more in price (they are about $500 USD now) so that I can archive up to 50 gigs of data per disk.
HTH..

Hi to all,
since i casually tracked an unknown object (almost surely a geosynchronous satellite) while i
was focusing the Moon using a C8 + orthoscopic eyepiece projection 6mm i need a moon
disk taken on April 29 in order to overlay with precision my videos and eventually to share
them.
Since my AstroIIDC was set to grab only 300 frames at once (: i had to continuosly restart the
grabbing losing some seconds of object translation.
The seeing was awful for such magnifying but i think that a good composition could be
interesting.
I grabbed an experimental complete mosaic in IR (900nm) on April 28 (11,5 days old moon)
but today i realized that ...i trashed the movies because i needed disk room!!!!
I was sure i did the backup but i was wrong (crying...sob sob).
It could be enough the side from Alpi's valley to the near pole.
As alternative it could be enough 12,5 days old moon even if grabbed in different period of
the year.
I posted an image in the file section with a rough and fast reconstruction of the event.
Anticipated thanks.
Best regards to all
Alberto Mayer
