Re: plastic/ vinyl storage shed used as scope shel

Posted By vladimir steblina

I have a roll-off roof and a Pro-Dome. The roll-off is wood and it does get moist during winter. I just leave on a Delonghi heater during winter and it works fine. Keeps the computers warmed up.

Not sure how to get rid of moisture in the summer time as our humidity in the summer runs in the teens so it hasn't been an issue.

In the dome humidity hasn't been an issue. It's in an off-grid location so electric heaters are out of the question. Not sure why the dome has less of a humidity issue since it is in a more humid environment (a mountain meadow). Maybe its the fiberglass and better seal.

Hope this helps.

AP900 Height of Pier Question

Posted By vladimir steblina

I am getting an AP900 mount. But I am wondering what height pier to get with the tripod. I plan to place a C11 on it. The inside wall height of my observatory is five feet. I need to make sure that the slide off roof will close. I would also like to use with the Kendrick tent.

So what do I tell AP for the height? Any help would be welcomed. I do have their spreadsheet, but I'm looking for a quick and dirty answer.

She's pretty intense during hunting season. However, as soon as season is over she is pretty chill.

Meteor and possible meterorite in eastern Washingt

Posted By vladimir steblina

This was the Wenatchee World article today on a meteor in eastern Washington. Note the pilots comments about it striking the ground and becoming a meteorite!!!

The country around Lind-Coulee is mostly wheatfields with a little bit of sage in the draws.

Should be fairly easy country for a recovery.

SPOKANE (AP) — A meteor streaked through the sky over the Pacific Northwest and apparently landed in Eastern Washington early today.


A Horizon Airlines pilot reported seeing the meteor hit Earth with a flash and a burst of light near Highway 26 and the Lind-Hatton Road in the southeast corner of Adams County about 5:25 a.m., said Mike Fergus, a Federal Aviation Administration spokesman in Seattle.

Sheriff's dispatchers said they had no reports of damage. Washington State Patrol Lt. Robert D. Kerwin said there was no indication of a traffic disruption.

Fergus said he did not have the pilot's flight number, point of origin, destination or altitude at the time of the sighting.

A number of pilots reported seeing the meteor streaking through the sky from Boise, Idaho, into Washington state, an FAA duty officer said without giving his name.

In Wenatchee, RiverCom dispatchers started getting calls right after the meteor apparently hit at 5:25 a.m., said Millie Tirapelle, the Wenatchee dispatch center's director.

"We got calls from Entiat, Monitor, from motorists that were out towards Crescent Bar, Badger Mountain and Waterville," said Tirapelle. "Everyone, of course, seemed to think it was in their backyard, but of course it was observed statewide."

She said no record was kept of how many calls were received, but that "the phones were ringing off the hook."

People reported seeing "at least one big light, then another one," said Tirapelle.

Wendell Holve, a Chelan County sheriff's deputy, said he was in his patrol car at a parking lot in Monitor when he saw what looked "like a fireball, almost like a shooting star but a lot closer."

Holve said he was looking southeast and the object looked like it was going right over Wenatchee. He said it had a very white or bluish-white tail.

"It was extremely bright. I mean it lit up the sky," Holve said. "It was pretty impressive."

Ray Eickmeyer of Entiat told a KING 5 Seattle TV reporter this morning that he was traveling southbound on Highway 97A when he saw what he described as a very large shooting star come down east of the Waterville Plateau. He said the object was "traffic-light green" in color and that he saw several flashes of light on the horizon after it apparently hit the ground.

Television stations in Spokane reported getting viewer calls from across Washington and northern Idaho and parts of Oregon and southeastern British Columbia starting at about 5:30 a.m.

The callers said it resembled summer lightning, a rocket, a satellite or an exploding transformer. A woman in Walla Walla, about 55 miles south-southeast of the reported crash site, said she heard a sonic boom and felt a shock wave not long after seeing the streaking meteor.

McCain's and Obama's College Transcripts

Posted By vladimir steblina

When I was hiring people one of the most informative documents were people's college transcripts. It was interesting to see how their selection of classes changed over their education. Grades were important in showing trends over time.

So where can we find McCain's and Obama's college transcripts??

Anybody have an on-line source? Since they release their health and financial statements I suppose their transcripts should also be available.

Binning in DSLR Camera's

Posted By vladimir steblina

I posted this note in a photography forum. Nobody had an answer. Hopefully I will have better luck in this forum. Thanks.

I come from an astronomical imaging background. My astronomical CCD camera allows what they call binning. That is, when I bin the CCD it increases the pixel size and the sensitivity.

I notice on the new Canon D50 that they have two sRAW setting which result in much smaller sRAW files. Does anybody know if these sRAW setting are achieved by binning the CCD? This would result in much greater sensitivity than the RAW setting.

Since I am interested in using my photography camera's for pretty pictures of the night sky I would be interested in knowing how they work. The astronomical CCD camera's have certain parameters that have to be met to meet scientific standards.

So the question is "Does anybody know how the sRAW settings are achieved?" and "Does using the sRAW setting result in greater sensitivity?"

Then I found this comment on the web about the Canon 50D.

* Pixel binning for high ISOs. A new technology enabled by the complexity and processing power of DIGIC IV where they can bin 2, 4 or 8 pixels together at the raw level and average out the noise between them. This is seen by Canon as a key technology in balancing very high resolution sensors (in the 50mp range) with low noise at very high ISOs. Right now they are not pushing this too much with the 50D so as to not create confusion in the market (they see more potential for the technology as sensors get larger and in the pro-market).

So does this mean that you cannot bin with the older DSLR camera's but you can with the new Canon 50D??

What is it??

Posted By vladimir steblina

I got this as a gift with a bunch of astronomy stuff. It looks like a telecompressor.

Very well made. No identifying marks at all. It just smells like a Astro-Physics product, but I cannot tell for sure.

Threads do not fit my ED-80. Large lens side is 2 3/4 inches at the threads. Small lens side is 1 7/8 inches. It comes apart as shown in the photo's.

Any guess??? It is probably a product of the late 80's early 90's judging by the other stuff. It was just in a box.

Red cap plug says ED-40 on it. Also has number NAS-813-40. I am NOT certain that this belongs with the item.

I have a couple more pictures on the classified site.

Thanks...all guess are welcome and will be treated with respect.

Binning in DSLR camera's

Posted By vladimir steblina

Sony and Fuji just offered new cameras that incorporate binning for low light photography.

Here is the article:

Unfortunately, they are point and shoots. Any guess before this feature is offered in a DSLR? The other question would this be just a firmware fix??
