- Fisheye lenses cost a lot more to replace that first surface mirrors.
- In time (this technology is commercially only two years old
remember), first surface mirrors will no longer be as prone to damage.
- First surface mirrors do not carry prohibitive patents.

The future is mirror projection - not fisheye  :-)

This is why I (mostly) stay quiet during discussion of quality
comparisons, namely, there is no way of knowing how well the
underlying system has been configured, what software used,
what mirror used, what projector, and so on. Unlike the
fisheye products there are more variables with the spherical
mirror and the current commercial players don't necessarily
offer the optimal hardware or software.

Well ... with assistance by myself, granted only through emails
so certainly the result he has achieved is in no small part due to
care and skill on his part.

The point is though that such a system can be set up independently
by those who feel that's the way they want to go, for budget or
other reasons. And it can be setup to yield equivalent quality to
a fisheye lens based system, at least that is my experience in my
3m iDome and 6m inflatable.

While I haven't seen Jacks dome I have no reason to believe it is
not optimal given the projector resolution he is using, namely
SXGA+. At this point I should point out that the resolution
improvement going from SXGA+ to a HD projector is significant,
all others things being equal. This is more than simple considerations
based upon the resolution difference.

Just to show I'm not totally biased. :-)

But "First surface mirrors are" much "more prone to damage
than fisheye lenses".

> -  (this technology is commercially only two years old remember),

Hmmm, I did a couple of commercial installations in the 2005
range while still at Swinburne, including Cosmodome mid 2005.

> In time first surface mirrors will no longer be as prone to damage.

Please let me know when you have these better mirrors, I'll be a
willing customer. You have no idea how much time and money I
have spent on investigating mirror technology, I thought the
software would be the weak link but it turned out to be the mirror.
Fortunately for me since I only (mostly) do research or fixed
domes I have a more controlled environment than the portable
industry so the current mirrors are more than adequate.

ps: Currently have plans next year for a steel worker to polish a
1/2 sphere from which 2 mirrors will be cut (assuming I choose
to invest some of my available R&D budget). If it works they will
be strong enough but not necessarily lower cost. Initial tests
show that the mirror quality is at least as good as the current
mirrors.

> The future is mirror projection - not fisheye  :-)

Brave statement, I would not necessarily agree with it. How about
"the future of _budget_ dome projection is a spherical mirror".

My bet on the future of digital dome projection is ... woops that's
still supposed to be a secret.

Lionel mentioned the International Year of Astronomy in his post, so
this seems like a good time to find out what everyone is doing. After
all, January 1 will be here before we know it!

In case you're unfamiliar with IYA, here's a link to the homepage:
http://www.astronomy2009.org/

First, I want to tell you all that I personally have put in a lot of
hours creating Stellarium resources to be used for IYA topics. I hope
you'll take advantage of some or all of these.

1) I wrote eight Stellarium scripts and narrations pertaining to dark
sky issues. There are four script topics, one set for the northern
hemisphere and one set for the southern hemisphere. Because the
narrations are live rather than prerecorded, I built pauses into the
Stellarium scripts so that you don't have to talk really fast or
really slowly to keep up with the script actions (the narration text
tells you where the pauses are). Script topics are:

* Apparent magnitude: What the term means; how it helps astronomers
quantify light pollution; etc.

* Finding Orion in the sky: Self-explanatory.

* General overview of light pollution on the night sky, focusing on
the appearance of Orion: As you probably guessed, this script asks
people to observe Orion under different amounts of light pollution.

* Orion and the GLOBE at Night program: For those of you unfamiliar
with GLOBE, the idea is that people observe Orion once or more during
a two week period in mid- to late March, then report the limiting
apparent magnitude visible from their location using a set of sky
charts. This script emphasizes how to correctly determine the limiting
magnitude visible from your area, so that the collected data is as
accurate as possible. Here's a link to the GLOBE homepage:
http://www.globe.gov/GaN/

All of the Stellarium scripts are set for March 21, 2009, which is
approximately in the middle of the GLOBE data collection period. FYI,
since the latest desktop version of Stellarium has not yet had the
scripting code added back in, these scripts are written for Stellarium
0.9.1.

The scripts, suggested narrations, Stellarium 0.9.1, and numerous
other resources (videos, etc.) are being compiled on a DVD by Chuck
Bueter. The DVD will be available for purchase any day now, and the
price should be minimal, just enough to cover the costs of duplication
and mailing. You can learn more here:
http://www.lettherebenight.com/pltm.html

2) I also compiled resources and stories for the Cultural Astronomy
working group. See:
http://astronomy2009.us/storytelling/sky-stories-stellariums-collections-of-cele\
stial-lore/


In early April, 2009, I'll be doing portable planetarium shows for the
public, as part of the "100 Hours of Astronomy" event. I'll be
partnering with our local astronomy club for this, and they have a set
of table top exhibits which will nicely supplement planetarium
lessons. Hopefully the sky will be clear (always a gamble here in
western Washington) and we'll be able to look at the real night sky, too.

So, that's a long introduction to what I've done and am going to do.

What are your plans?

Cheers,
Karrie

Hi Karrie,

      We too are working on our IYA2009 plans here in Decatur Illinois.
  Some of our plans include:

      Adopting the monthly themes as designated by NSN/ASP/NASA for all
of our monthly meetings being held throughout 2009.  Those monthly
themes are available here:
            http://www.astrosociety.org/iya/guides.html

      We are also working with our local Conservation District on some
special events throughout 2009.  At least 2, more likely 3 or 4

      We are going to be meeting with our local Park District in the
next few weeks to discuss some monthly Astronomy in the Park events as
well.

Decatur IL is host to some pretty big events (boat races, Farm
Progress Show, Decatur Celebration), so we are hoping that the Park
District will allow us participate in these events.

      Our local University has asked if we would assist in a StarParty
that they are planning.

      And this is just the beginning.  It's going to be a busy busy year!

      And, Yes!, I can't wait to get my hands on one of the DVD's that
Chuck has been working on.  My name is on the list and I'm just
waiting for the email to let me know that they are ready to ship!!!

      Finally, let me say THANK YOU to you Karrie for all of your hard
work in helping to prepare materials for IAY2009.  I know you have
spents countless hours working on scripts and other materials and I
just wanted you to know how much it is appreciated.

Clear Skies!!!

You're more than welcome, Bryan! I hope the Stellarium scripts and
other materials on the DVD are helpful.

Good luck with your planning. It seems like your local Park District
should be willing to include you in at least some of those big events,
but sometimes things that should happen don't actually happen. Whether
that works out or not, it sounds like you won't be bored next year!

Cheers,
Karrie

No worries at all ... I mentioned it really only to hi-light the point
that one real strength of the spherical mirror approach is that
the end user, if they wish, can in fact do it themselves and get
a good result. It isn't for everyone, some people will have the
funds to invest in the simpler fisheye systems, others may choose
the spherical mirror from commercial suppliers. It's all about
choice given funding levels and available expertise, or perhaps
the preparedness to learn given the lack of the above. The problem
from my perspective (since I am obviously associated with the
spherical technology) is when comparisons are being made with
commercial entities who may or may be exploiting the spherical
technology to it's fullest. I know the spherical mirror approach
competes favourably with the fisheye systems in some cases, I
also know the fisheye systems are superior in other cases. I only
have an issue with commercial entities on both sides who claim
otherwise. :-)

Hopefully this thread can move on to the real question, content
creation. In particular, software package XYZ supporting fisheye
and warped fisheye.

Due to recent questions on optimal resolution with
spherical mirror projection, I've added some additional
notes to the FAQ. Note that there are lots of factors
that related to dome experiences and image quality
is just one ... but might as well start with optimal
hardware configurations. I apologise if that these
additions are mostly Apple Mac based, but that is
what I use and the principles will apply to other
systems as well.

1. Significant improvements in colour fidelity can
be achieved with colour calibration.

2. There is some confusion when it comes to display
vs projector resolution when in mirror mode or using
"screencopy" methods.

Seasonal Greetings to everybody from Down Under.
On the eve of the I.Y.o.A, it is worth perhaps mentioning the link
between Astronomy and International Maritime Heritage.
Every ship of discovery sent out by the Portuguese in the 15th Century,
sponsored by Prince Henry the Navigator, carried Astronomers. Nautical
Astronomy became a Science.
As a former, pre GPS, maritime navigator and Maritime Museum Director,
these are parallel personal interests.

Actually, if you are a member of IPS, you'll the set for free.
Likewise, several
of the planetarium regions are sending them out to all their members.
Also, of course, I would suggest you go to the official International
Dark Sky Association website http://www.darksky.org

Hi everyone,

Greg here. I have canceled my account with the host of the forum site.
After checking the usage logs, and finding that the site had no
visitors for many months, I could no longer justify the expense of the
site. I was not able to back up the files on the site, and I just had
no time to clean up the porn posts. I'm very sorry if valuable posts
were lost, but it seemed that everyone just felt more comfortable with
this group format, and the other forum.

On a very positive note, it's wonderful to see all the activity here
on the YahooGroup! Paul is doing great job of moderating, and things
have really taken off. Terry, you were member #1, did you ever expect
to see so many other like-minded folks?

I'm still in Thailand for now. I will most likely be moving back to
the States within the next few months, and I can't wait to get back
involved in the group. I have too many hobbies that need indulging!

Greg

As far as I have been able to determine it is a Spitz Model A  (a "Deluxe" version with lenses as opposed to the "Standard" version that came without lenses).

Thanks Greg, although I note this is from perhaps 6 months ago.

As it happens the moderation of the group has been (fortunately)
light ... only a few instances of inappropriate posts. New members
apply perhaps 1 a week on average but they only take seconds to
process. There were some issues at one stage with photographic
uploads, which (like new members) are now also moderated.

My one concern is that the group might end up primarily discussing
spherical mirror projection, something that might in no small part
be a reflection of my contributions to the group. In any case that
discussion does seem to have reduced since I assembled the FAQ
on the topic.

I would also welcome feedback/input from members on this group,
how to improve it, what would make it of more interest to yourself,
and so on ...

One question I always get from people is if there is a master list of known shows that could be played on either fisheye or warped fisheye systems.
I think it would really help people out if that was listed somewhere.

Do you mean "shows" as in movies, or content in general?

If the former, then all movies made for fulldome (ie: fisheye)
can be played and warped on the fly. This then becomes a
question of the users computer hardware. A very brief
summary is below, noting that the comments with each one
are my personal opinions. If anyone knows of other options
please let us know.

- Apple Mac with Quartz Composer  and my "pbmesh" patch
and optional custom mesh. Can suffer in performance
compared to warpplayer for high resolution movies for HD
projection. Supports multiple movie formats (fisheye,
spherical, etc) including interactivity.
Plays "any" QuickTIme movie.
Free.
http://local.wasp.uwa.edu.au/~pbourke/miscellaneous/warppatch/

- Apple Mac with my "warpplayer" and optional custom mesh.
Supports multiple movie formats (fisheye, spherical, etc)
including interactivity.
Plays "any" QuickTIme movie.
Not free.
http://local.wasp.uwa.edu.au/~pbourke/miscellaneous/warpplayer/

- Apple Mac with Swinburnes "screencopy" software and/or
their "MDPlayer". I haven't tested these. I have doubts about
the quality of the screencopy technique for other than low
resolution projection systems. Perhaps someone at Swinburne
would like to comment on MDPlayer, in particular, whether it
optimally uses the available projector resolution.
Plays "any" QuickTIme movie.
Not free.
http://vr.swin.edu.au/mirrordome/software.html

- MSWindows. I am not aware of any movie warping playback
solutions on this platform.

- Linux. I am not aware of any movie warping playback
solutions on this platform.

Notes.

- For all platforms one can obviously prewarp the movies, most
will already be aware of my distaste for this approach.

- "mplayer". While this movie player and the warping functionality
are supposedly supported on all three platforms, I've only tried it
on Linux. I haven't found it reliable enough for production work
and in my opinion doesn't support geometry correction support
required for precise warping.

There's a fulldome Wikipedia that might be of interest to some or all
of you:

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

It doesn't break down movie content into fisheye or spherical mirror
formats, but it does have a lot of good information. I also don't
recall that webpage being mentioned here before, at least not
recently. Sorry if I simply had a memory lapse about it.

Happy 2009 to you all!
