Photoshop CS2 Activation Question

Posted By Chris Nisbet

I just installed CS2 and the program says it must be activated to use after 30 days which is fine. When I go to "Help" then click on "Activate", nothing happens. The "Transfer Activation" is grayed out. Also, it says there is a reminder to activate the software that should display when the program is run but mine does not. What am I missing or is it not necessary to do this anymore?

Why Does My Dark Frame Look Like This?

Posted By Chris Nisbet

Title says it all. This dark frame was taken with a ST-8XME, 5 minutes @ -35C. Why the gradient? No matter what I do, the 5 minute dark frame looks like this. All was well a couple nights ago-dark frames were normal. Any thoughts?

Nothing Better Than A Frosty C11

Posted By Chris Nisbet

Nothing better than walking out to "The Shed" after a successful imaging session and seeing a frosty C11!

(it's April 13 and I still have 2 inches of snow on the ground)

ARP 273

Posted By Chris Nisbet

Here is one you don't see everyday. Taken at prime focus of a 1992 C11 (measured focal length of ~3210mm)last fall, MI-250, with an ST-8XME, binned 2x2,40 subs @ 4 min each. Only processed in CCDSoft. Just learning about Photoshop.

M1 But With An Equipment Question

Posted By Chris Nisbet

This was taken with a C11, prime focus,Pyxis camera rotator, AO-8,CFW-10 and an ST8-XME (efl 3370mm). I had just finished collimating the scope and wanted to take a quick picture to confirm the collimation. It was cold out (-5 F) and during the exposue, the camera setup slipped but I never lost tracking. This is the image that came back. What I see in this image is that "sweet spot" of the C11 is not centered on the chip. Stars in the upper left are almost round while the lower part are clearly not. Do you see the same thing and, if so, how does one get the "sweet spot" centered on the chip?

Ammunition Depletion

Posted By Chris Nisbet

I live in the Minneapolis MN area and cannot find ammo for my 9mm and .45 Ruger pistols. The stores say that when they get a shipment in, people come in and buy the whole shipment. I've been to several Wal-Marts and sports stores to no avail. Even the stores that are charging 40-50% more than the Wal-Mart price are out. Anybody else seeing this in their area of the counrty?

Abell 53 in Aquila

Posted By Chris Nisbet

Here's one you don't see everyday-Abell 53 (PK 40-0.1) in Aquila. Took this last night before the moon came up. Here in Minneapolis MN this time of year, twilght hangs on until about 10:30pm and with the moon rising about 11:30, it didn't leave much time to image. But, it seemed to turn out fine.

Here are the details-C11 @ f/12, MI-250, ST-8XME binned 2x2, AO8 correcting every 1 sec, 10x5 min subs, darks and flats applied. Only processed in CCDSoft using Add combine. Seeing conditions weren't too bad for a change. Outside temp was around 55 deg F.

If my info is correct, the central star is at around magnitude 20.

Supernova 2009ga NGC 7678 Arp 28

Posted By Chris Nisbet

The other night I decided to image Arp 28 for no particular reason other than it was low on the eastern horizon and I could image for a long time without a meridian flip. When I processed the image this morning, I noticed a "star" seemingly in NGC 7678 that wasn't supposed to be there. A quick check on the internet revealed that it is Supernova 2009ga discovered in June. No supernova discovery for me! Anyway, it was "cool" to discover something that you weren't expecting.
Some of these Arp galaxies sure are small although I do enjoy the imaging challenge even though I am only 25 miles north of Minneapolis/St Paul MN.

Specs are as follows: C11 @ f/12,MI-250,Pyxis,AO8,ST8XME,-20C, 25x5min 2x2 subs.

Palomar 2

Posted By Chris Nisbet

Here is a globular that doesn't seem to get much attention. Nothing too special about this except knowing that this is the only globular in Auriga and it is far away from most other globulars in our galaxy. Plus it ain't very big compared to others.

Taken this morning with a C11 @ f/12,MI-250,ST-8XME,15x6 min,2x2 bin,AO-8.

Palomar 1

Posted By Chris Nisbet

I have no idea why I am trying to image such small and faint objects. I must enjoy the technical challenges of imaging small objects at long focal lengths. Or just that there doesn't seem to be a lot of people imaging these obscure objects. Anyway,not too exciting visually but just knowing what it is is kinda cool. I like the negative image better on this faint cluster. Doesn't compare to the Hubble picture though(which is cool with all the faint background galaxies)!

Palomar 1 taken this morning, 30x6 min, ST-8XME,2x2 bin,Pyxis,AO-8,MI-250,1992 C11 @ f/12. Processing only in CCDSoft. Seeing conditions in Minneapolis have been very hazy for the past two weeks.
