AP1200 and POTH

Gianluca
 

Hi,

I intend to connect both TheSky and MaxIm DL 5 to the scope using the POTH as a hub. Since POTH offers the possibilty to pulse guide the mount instead of using guider relays, I would like to know if this is correct so that I can dispense of the guider cable!!!!!


Thanks

Re: New Book, "Best Targets for Astrophotography" on AP mounts

Dean S
 

Very nice Ruben, wish I would have had this earlier in my imaging hobby.

It looks like it covers most all of the popular targets season by season,
and a few I have somehow missed over the years. I always wished for a book
like this giving a 'schedule' of when objects where at their best.

A great idea book for those nights when there seems to be 'nothing' in the
sky to image or observe. Good imaging pointers and advice along the way
too. Your quick processing tips should be helpful as well.

I would recommend this book, and already have to several people.

Dean

Hi group,
After ten years of using AP mounts for astrophotography, I have put
together a book of my experiences, published by Springer. All 115 images in
the book were taken on AP mounts, including the AP400GTO, the AP900GTO, and
the AP1200GTO. I used a variety of telescopes and camera lenses with focal
lengths from 180mm to 2300mm.

The full title is, "The 100 Best Targets for Astrophotography: A Monthly
Guide to CCD Imaging with Amateur Telescopes". For each target, the book
walks you through the steps of choosing an object, acquiring the image, and
then processing the data. A second section of the book, entitled "Getting
Started in CCD Imaging," begins with the paragraph, "The most important
element in astrophotography is accurate tracking....one minute of poor
tracking ruins the most pristine view." The excellent performance of the AP
mounts is described.

The book is available from a variety of book vendors and some astronomy
stores. Amazon.com allows a preview of several pages of the book, and has
reader reviews.

Nice one, Dave! Especially for being from Yorba Linda. Your scope was probably pointed right in my direction for that one (Ontario).

Got a trailer hitch?

Your local hardware store has a bolt that will match the CW shaft. Thread the shaft on, then place your counterweights on the shaft.

No floorboard? You have an SUV with folded rear-seats? Floorboard of front passenger. Passenger complains? Tell them to buy you a truck. :)

Really folks - case or not, put those cw's on a floorboard. That case isn't going to stop the force (F=M*A) of that cw package slamming into your gear all that well. All a padded cases does is make for more rounded dents. :)

Re: Transporting counterweights- best method?

Hi Fernando,

I'm in the same boat... trying to figure out the best way to transport a few things, including the counterweights and shaft, in one case. My plan right now, is to line a toolbox with dense, closed cell foam and create two compartments, one large for the counterweight shaft and three 10 pound weights (mounted to the shaft), and a smaller compartment for the hand controller.

I may put a plank of wood at the bottom of the large compartment to better distribute the weight so they don't sink through the foam.

I used to place towel-wrapped counterweights in a soft bag and place the shaft on the floor, but things move around too much and I've had the threads on the shaft cut some grooves into the rubber floor mats... hence the idea for a consolidated hard case. :)

Best,
Danny

Hi Guys,
I just couldn't resist.
I simply wrap mine in an old towel and place in the floorboard, trunk, or truck bed. Cost = $0, Worth = Priceless! Time = 0 minutes

If everything is working so well, that you have time to design counterweight carrying boxes, you have made it to the top!
Thanks, Rick

For a truck or trunk of a car that is true. I have an SUV which I put down the two backseats to form a deck to transport everything. There really isn't anything to hold things from sliding back and forth between the back of the front seats and the tailgate. Scope (in carrying case) and other equipment including lap top all share the same flat surface.

Don,

Right, but I don't keep people and scopes on my rear floorboard - which
is where I put the cw's. Of course, scopes and mounts get wrapped and
packed properly. In 8+ years of toting these things around, I've yet to
have a scope fall onto the floorboard and hit one of my cw's, and a cw
has never rolled up off my floorboard and hit a scope or person. I don't
think they ever will, unless the truck flips - in which case I don't
care about the cw's. :)

cheers & beers,
Chris
