CCD autopilot vs ACP

Started this discussion. Last reply by Marc Basti Nov 11, 2014. 6 Replies

Kind of liking CCD autopilot. Have both systems, but I'm preferring CCD autopilot. Just easier to understand. Now that my guider is picking up stars easily CCDAP seems to be doing the job. Of course…Continue

Best telescope tool I ever bought. Little pricey, but got a discount. My scope was way out of collimation as I was overscrewing around stars at night trying to get it perfect. Thing was way out of…Continue

Plate solving

plate solving is an advanced technique where the telescope will slew to exactly where it previously was to line up with the stars in a shot perfectly, so as to continue a shot or start again a new night, etc.

"Sounds like it'll be plenty solid Charles. I went 40" deep and 24" square on both of mine and the only movement I got was during the last couple of earthquakes we had. No damage so life is good :)"

New deck and observatory install

Got the deck taken out, and my buddy and his small crew put in an 18 inch round pier with a T base 5 feet deep. The dirt in my hill is super strong and solid, and I'm guessing that pier base isn't moving at all if much at all. Just levelled the J bolts (except he used screws with flat square 3 inch plates on the end. It'll be solid. So, that part is done. Monday they install the actual deck, should be done my tuesday. Wed. my observatory shows up. Can't wait.See More

"SGP seems like a decent program to try out-I've only heard good things about it and a good price. On my to do list 2015. Marc"

"I might switch to ACP.. Lane and McFarlin are killing it using that program and swear it's easier than CCDap but harder to figure out at first. Maybe I'll switch when I set up my observatory again in a month."

"Since I switched to Sequence Generator Pro I have no issues at all, I set up a time for it to start tell it the target and let it go. Great little program."

Switching to ACP

Posted on September 25, 2012 at 4:20am 6 Comments

CCDap is so unstable. Actually going to try the free program Steve Coates turned us onto tomorrow, but man CCDap is just unstable. When it works it's awesome when it doesn't it blows a night, and it seems to be 50/50. ACP apparently much more stable.

Wonder how much it would cost to have your own like 20 inch orbiting telescope.

Not too big a deal, but I'm pretty stoked. Irony is, I share a step mother with David Goldstein but I've only met him once or twice. funny.

Hi Charles
If you are looking for a Ha Solar Scope there are a few nice options you may wish to consider. Solarscope http://www.solarscope.co.uk/products.html and Daystar http://www.daystarfilters.com/Quantum.shtml have Premium Ha filter systems that will mount to your existing refractor to turn them into very high quality solar instrument. One of my friends has a Solarscope filter system that just blows away the Coronado or Lunt scopes. I have heard nothing but good about Daystar but have no experience with them.
Something to consider since you tend to like the best

Interesting you said that because I've been of the same mind. I considered starting small and stretching to better, but finally after all I've read I decided to go for a higher end from the get go - an aplanatic 11" with CGEM DX mount. My only hesitation was a) it may be more than I can handle (I'm quite fit now at 59, but in 15 or 20 years a 110 lb mount may prove daunting to haul around) and b) building that old 6" from scratch was an adventure. Buying a 'ready to go' scope may leave less opportunity for creativity and discovery. But I suspect I will have ample opportunity to tweak and upgrade and I get my feet wet in this. Time will tell.

At 7:12am on July 8, 2012, Frank Bastian said…

Well... maybe I can grow into something that ambitious! What do you think of the Celestron CGEM DX mount?

At 9:56pm on July 7, 2012, Frank Bastian said…

well, forgot to mention that I have a 6" ~ F6 newtonian I built years ago and also picked up a used 3" refractor that have both languished for lack of a decent mount. a priority is to get a good solid mount. my skies are pretty good when clear (mountains of Pennsylvania)

At 9:30pm on July 7, 2012, Frank Bastian said…

that's part of my dilemma - both. So I wanted something I can enjoy viewing with and cultivate a serious AP hobby too. I was torn between a large aperture SCT and large newtonian. I'd read that for viewing a short F newtonian was not ideal, but a 10" F5 newtonian would have a 48" tube - kind of cumbersome on for viewing with an equatorial mount.

I think where I've settled is the reality that there is no one perfect scope for both viewing and AP - I'll eventually want an SCT and a newtonian; maybe even a big dobsonian. I'm strongly motivated to go with a SC to start and build from there.
