Sorry, one more question. Can I just bolt the standard pier adapter to
the flat surface of my Pier-tech mount or do i have to have a FSA.

thanks

Re: Pier installation for AP1200GTO

Hi Chuck
I have same setup here in UK
I would put it central so you can get your imagers or your self under it when pointing north
You will need a lot of counter weight in it too.
And dont slew too fast ie 1200 but it will take the weight easy
Have fum

Hi all.
I'm getting ready to install a Pier-Tech 3 adjustable height pier in my
Boyd dome observatory. It will have a Meade 14" with a small refractor
piggybacked. It is going to be a tight fit.
Should the pier be installed dead center in the observatory or should
it be offset(to the South)??
Thank you,
Chuck/divenuts

I don't have first hand experience with Monolith, but do own the
Particle Wave Technologies Pinnacle. It is amazingly light weight
and extremely rigid. No doubt their Monolith is the same or even
more rigid.

Hi everyone.

I know, I know... "Not another group?!" But, yes, another group.

I've started a new group for amateur astronomers and astrophotographers
residing in the southern California area. I thought it might be a good place
for us to discuss locations, equipment, retailers, and maybe set up a mini
star party here and there.

http://groups.yahoo.com/group/SoCalAstroPhoto/

If you're in southern California and like astronomy, especially
astrophotography, please drop in and consider joining.

Thanks,

Subject: RBI paper from IS&T/SPIE's "Electronic Imaging Science and Technology Symposium" San Jose, Ca. Jan 2009


Last week I presented a peer-reviewed paper at the Imaging Science & Technology / SPIE's "Electronic Imaging" symposium that preceeds Photonics West each January in San Jose.

Morely Blouke, the founder of SiTE (the makers of the SIxxx backside illuminated CCDs that were made in the 90s, such as used in the FLI Dream Machine) was the session chair. When I introduced myself to him at the beginning of the day, he commented "we've not heard about RBI in a very long time, so I look forward to hearing your paper".

The paper was well received, with quite a number of questions following it. One part of the talk that particularly generated interest was the tie-in of amplifier luminescence to RBI. I had three post-presentation discussions with CMOS image sensor researchers that are having trouble with luminescence and they were seeking ideas on how to deal with it.

Luminescence is aggravated by biasing of the source follower in the output stage. Under modest gate drive conditions with high drain to source voltages, the transistor is vulnerable to impact ionization in the drain region and that results in NIR light being generated.

The tie-in to RBI is that the NIR light generated during a power-up transient injects charge into the RBI substrate traps that leaks into subsequent images. I don't believe this was fully appreciated prior to this paper. Morely told me after all was finished that he thought that was some really excellent data and a very interesting talk.

I sent my friends Jim Janesick )author of "the" definitive technology book on CCDs) and Phil Cizdziel (key technologist at Omnivision, formerly of Fairchild Imaging) copies of the presentation and paper and Jim commented that it was what he considered to be a "perfect paper": short and to the point with lots of good images, graphs and solid data with analysis. He said that unfortunately many of the technical conferences are going light on details and are increasingly being used for marketing fluff these days. He said this is the sort of paper he would have expected 20 years ago in that it was completely focused on the technical issues and not marketing fluff.

I deinitely agree that several of the papers were more marketing oriented and less technology focused, unlike the ISSCC, where I was the Program Chair for the year 2000 and was the Memory Subcommittee chair for several years in the '90s. Kodak presented a nice description of the new 5.4 micron interline technology platform, but the paper was definitely more of a 20,000 foot flyover than filled with annoying technical details... I'd have liked to hear more about the design of the pixel and the output signal processing chain for example.

Anyway, as I promised several months ago, here is the paper and presentation: this time with no pre-publication embargo applied. Now I can share the data publicly without violating my pre-publication agreement with SPIE....

Sorry, but the above does not make any sense. What data is corrupt? The
keypad cannot make the servo run "slow". There is no connection between the
electrical signals that make the motors turn and the keypad.

Your best bet is to contact Howard here at AP and he can work with you to
clear up any confusion that you have and help you to work through any problems
that you may have with the keypad. Howard is out today but may be back tomorrow.
Give the office a call to set up a time.

I have to say that I am impressed every day by the quality of this

Just need to work out the little problems.

George Hughes





I don't know how all these problems could be related, so I'm just
going to list everything.
After a hardrive crash forced a total rebuild of the imaging
computer
(all programs and drivers). Nothing has worked right. Not even
with
just the hand control alone.
The keypad is totally separate from any external computer. It is
not affected
by any computer ills whatsoever.

The keypad has lots of very powerful tools built-in to allow you to
troubleshoot any situation including the one you find yourself in
right now. I suspect
that you probably never use the keypad and don't know really how to
take
advantage of it. I also suspect that you have set the keypad to EXT
mode, which is
a BIG NO-NO (unless you really know how and why to use this
feature). DO NOT
set the keypad to EXT, even when you primarily use an external
computer to
control the mount. There is no reason to do so under normal
circumstances.

Here is how you can make your mount functional:

1) make sure your keypad is set to Autoconnect "No", if not, set it
there (DO
NOT USE EXT mode unless you really really know what you are
doing!!). Check
to make sure that your time, date and location entries are correct.

2) set your telescope on the west side of the mount pointing to the
horizon -
do it manually using the clutches.

3) with the keypad set to Autostart NO, turn on the power and go
thru the
startup menu. When you get to the startup choices, press "Resume
from Park 1".

4) now slew to any star or object which is up there right now (you
can slew
to the sun during the day for a test if you wish). Pick up the star
in a wide
field eyepiece, center it and press Rcal. You know what Rcal is on
the keypad?
It is probably the most useful tool on the keypad, so please
familiarize
yourself with this feature.

5) you can now connect your external computer to the mount servo
and link
your planetarium program to the mount.

I felt it was important to provide adequate protection for my precious

feel more secure during transport, but at home I was still uneasy. I
decided it was important enough to install an extra security system

I have followed the post in part reply to my enquiry about 4.2 which
Richard Kinsey
placed a question which you answered in some detail.
I am still waiting to learn if the newer version will contain a polar
alignment procedure
(similar to that in SS2K) where one starts in unaligned mode,
synchronises on two
stars, the switching to aligned mode , returning to one of the two
synchronised stars
then re center that star using the Dec and Az the synchronises again.
With this very
fast polar alignment facility which was quite good enough for
autoguiding I could set
up and be imaging in 10-15 minutes. Is it too much to ask for ?
