TAC Visual / Re: Advice needed for Pinnacles East
« on: Today at 05:01:02 AM »
its been quite a long time since I've been  to the Pinnacles East campground, but I'm remembering the bulk of the camping area is deep river sand, and it gets really dusty if its windy.

do let us know how the road and sign situation has worked out, because SCAC wants to visit Pinnacles West on July 22nd...

and in fact, after spending 2 days trying to find a group site or any campsite  within 2 hours drive of Glacier Point, the Santa Cruz Astronomy Club is canceling our appearance there.  I suspect we won't be the only ones this summer.

TAC Visual / Yosemite club weekends this year...
« on: June 12, 2017, 05:52:45 PM »
heads up, all you folks who join various astronomy clubs Glacier Point weekends.   The Bridalveil Creek Campground where they normally bunk 'us' won't open until August ....  and they aren't doing what they did in 2005, which was to put us at Badger Pass in an overflow parking lot, so my club, who has next weekend, is scrambling to find alternatives... EVERYTHING is booked solid except some $$$$ B&B kinda places in Oakhurst or Coarsegold (2 hours+ from Glacier Pt, ugh!)

yeah, got a good naked-eyeball on it for a few mins, but didn't feel like dragging out a scope.   my grab-n-go 10" needs mirror cleaning badly, my Discovery 17" requires too much setup time, and the Obsession 20" f/5 I just picked up, also needs a through dusting and optic cleaning before I can assemble it for the first time.   plus it too is a monster to setup (likely WILL be at GSSP this year, however!!)

TAC Imaging / Re: Using Astro Cameras on the Eclipse?
« on: June 02, 2017, 01:28:34 AM »
I'm fairly convinced I'm going to forgo any complicated photography attempts in favor of just watching and enjoying the eclipse.    I've rigged a white light solar filter for some 40x100 binoculars that have a 2 degree field of view, I figure I can remove the filter for the 2 minutes of totality then replace it

apparently the west road will be closed all night all june, with incredibly bright flashing signs facing the visitors center area.

NGC/IC Project / Re: Corrected NGC v0 online

I think trying to implement Astrometry on the web server is a bit ambitious for now.   The current graphics are all static JPG files, and I think our initial goal should be to get back to the level of content that the old site had, all the background material and such.

TAC Imaging / Re: Lunar imaging question
« on: April 26, 2017, 03:18:47 PM »
I'd just adjust one factor, the gain, at least until you run into some sort of limitation....   lowering gain shouldn't increase noise, which is your biggest enemy.

1/200th is 5 milliseconds (1/200 = 0.005)

of course, I have no idea how to correlate your "gain" setting to ISO.

using a regular (DSLR) camera, I've based my lunar exposures on daylight. good old 'sunny 16' rule,   shutter speed == ISO at f/16.    f/10 (your C8) is about 1 stop faster than f/11, so if you're using ISO 100 equivalent, then try 1/200th.

NGC/IC Project / Corrected NGC v0 online

I've crudely organized the raw NGC html files I got from Akarsh in folders per 100, and put them up here, http://www.ngcicproject.org/NGC/  so at least there's SOMETHING here.

So who has the IC data?

I'd prefer the people with server access all be locals known to us long timers, vs who knows who from cloudy nights.

so who's good with web scripting?      we need someone to take point on building a simple framework for the ngcicproject website.

the server is centos 6, can run php, perl, python, and I can probably setup most anything else, but I'd prefer any development is in something relatively mainstream and not new wave stuff like node.js or ruby, so I don't need to learn a new language to fix it.    I personally would prefer using a postgresql database, but I can manage mysql too.   I should be able to take the raw notes and munge them into database format, if you want to go that way, or just run with static .html files for each object, whatever.

you can probably pull a lot of the static text off here, https://web.archive.org/web/20170102050935/http://www.ngcicproject.org

I already have .htm files with images for the entire NGC catalog courtesy of Akarsh, and hope to cobble up a lookup page for that in the next day or so.
