Hello All,



I Apologize if you have already read this on the SBIG site, but

thought I'd ask for help here as well.



I'm not ready for the "sBIG-boy" CCD world just yet (I'm an old dog,

and trying to learn new tricks comes slowly! :o) but am in need of

autoguider advice for my more modest imaging efforts.



Having given up on film-based imaging (but gaining a newfound respect

for those who do it so well), I became hooked on digicam imaging,

starting out with a Nikon CP995 and now moving over to a Canon D60.



The exposure limits of the CoolPix were much more forgiving than the

with the longer shots possible with the D60, hence my newfound need

for an autoguider. I'd like to have minimal extra equipment at the

mounts (AP900 and AP600GTO) but am open to using my laptop if need be.



Any suggestions, warnings, or help you can give is appeciated!



At least the my H-a shots don't need guiding... here's one of the

first from the D60 (taken yesterday afternoon):

Autoguiders like the ST4, STV and even an ST7 can be used with any kind of

camera. However, I would guess that an uncooled consumer camera would be

limited to no more than 1 minute exposures before noise begins to dominate.

If you spend a bit of time drift aligning your mount and training the

periodic error correction, you should be able to take unguided images. With

careful setup, I have taken many 60 second and 120 second images with my

HX516 CCD camera through my 8" F12.5 Mak-Cass. on my 900 mount. A few shots

may show stars not quite round, but after combining 8 to 10 sets, the stars

do become quite round and the resolution is quite a bit better than any one

single exposure.



One other thing you might consider. SBIG has a new lower cost large chip CCD

camera, the ST2000 with built-in guider chip. This camera will be heads above

anything you will be able to do with the D60. By the time you buy an

autoguider and associated claptrap (off-axis guide mechanism or seperate

guide scope), you can almost buy the ST2000 and be done with it. With this

camera your productivity will be an order of magnitude higher than with what

you have in mind. Just ask the guys who went through the other routes and now

won't ever again part with their self guiding SBIG cameras.

I know it's "old" technology, but I just love my ST4. I'll never sell it

and I hope it lives forever. What a work horse! I even use it with my ST8

I can build the Binobacks to work for 54mm to 76mm IPD. You're narrower

than 54mm ?

If I am going to go for a 200 I would bypass all three that you have

mentioned here and settle for a TEC fluorite version, I realize that

it requires a little more pocket change, but that is what I would

consider.

#30092 Nov 18, 2005

Joe, I was attempting humor in indicating I have little space between

my eyes! I should always follow advice given to me to "tell people

when you are joking, you are so bad at it". A twin 200 apo

binoviewer would be pretty amazing. I hate to think of the mount

needed. Regards, Mark

Did AP produce F/7 version of their 8" apo? Man you are sitting on a

gold mine, if the slower version goes for 100K this one should be

worth at least twice that amount.



Thanks,

Vahe



----------------------------

#30098 Nov 19, 2005

Vahe, actually the AP206 is a F/7.9. These were made I think for a 2

year run in early 90's. The only other 8 inch AP I am aware of is a

8inch F/15, made in late 80's (this may be fable). I am not aware of a

206/f7 (my mistake in prior message). I don't know where you got the

$100,000 from,but would be nice though. Joe

Thanks to you and others for their advice on this topic. I got a lot

PS--Joe, the 100k comes from Herb York's Astromart ad for his 8" AP.

Joe: my 7" f/7 will be at WSP too ...

Since he bought Jack Newton's place at Chiefland, he doesn't get down to

WSP ...

He goes to Chiefland several times a year now that he is retired.

It was near the area where you normally are set up but closer to

the road. A little east of where the binocular Newtonian (16"?) was

located.
