Re: Park 4 or Park 5 using ASCOM V2 on AP900GTO #ASCOM_V2_Driver

Hi KHursh and Mike
I have the same setup CP3/V chip and ASCOM V2 driver does have the position 4 and 5.. The problem is that it just doesn't go to that position .. Very odd. I am not sure if this needs some kind of setup (I just setup the mount in the new observatory and didn't really change anything

I don't use hand controller (it is not connected) and I control the mount just with the PC. 


Thanks
Anis

FWIW, I looked at the .fits files from projects earlier this year, when I was using the Baader Vario-Finder for guiding instead of the QSI's OAG.  The guiding results were at least as good as what I'm getting now.

I have a 900GTO with a CP3 and V chip. I use the ASCOM driver to set "Park to" and I tell it to park to Park 5. Works every time with SGP or NINA when it's finished with a session.

I have a CP3 controller and I can go to Park 4.  I have upgraded my hand controller to the latest version and the ASCOM V2. Park 4 shows up in my hand controller and I use it to take my flats.

Hi All,

I have been using my AP900GTO with CP3 (V chip) for few years. now and it has been very good. I always used Park 3 position and operated with just SGP and ASCOM driver (not APCC).

I am working on setting up in a remote observatory and I need to set the scope in Park 4 position (For roof park detection and operation). However, whenever I try to use Park 4 (or Park 5), the mount doesn't seem to the horizontal CW position . The RA just swing a small amount and the scope basically. wants to twist 180 degrees. But It goes to Park 3 correctly (Plate-solving etc are all working perfectly).
I have the pretty new  ASCOM V2 (may not be absolute latest but may. be a month old). I cant do user defined park position as well using just the ASCOM driver.

My question is: Do I need to get APCC to get this working properly? I do see park 4/5 as options in the ASCOM driver so I thought it should be working .

TIA and Regards
Anis

Lock it down is what I do. Some may smile at my method, but it works: <http://astronomy.mdodd.com/observatory.html#Autoguiding>

My 60mm f/5 guide scope no longer has a focuser mechanism, and the camera is bolted to a bracket on a dovetail plate. I loosen the bolt, and nudge the camera while my wife at the computer tells me if focus is better or worse.

It takes about five minutes. I tighten the bolt, and we're done for many months.

Clear skies.

You can create custom park positions in APCC to point anywhere.

Thank you Rolando. 

If I get APCC, can I use Park 1 as custom park position? I just need it to park in the same spot everytime for park confirmation for roof to close and for flat panel position on the wall.

I tried the Baader fine focus but in the end I bought a helical focuser which is much easier to use. Screwing and unscrewing the front lens to focus was a pain because it unlocks the lens which has to be locked again.

What is best practice for using the fine focus?

Assuming you use MaxImDL, what is your Min Mov?  What is your guide camera?  I have the SX Superstar.  Back in 2014, when I was planning to buy the Baader, I was advised that the smaller pixels of the Superstar (compared to the version of the Lodestar available at the time) would be better suited to the Baader Vario-Finder.  Right now I'm inclined to think that one of the newer CMOS cameras with even tinier pixels might be the better bet.


Re: Unguided tracking with a 1200?

Joe Zeglinski
 

Hi Peter,
 
    I’ve been regularly  doing 15 minute unguided photos with an RCOS-14.5 an my old AP-1200/CP4, and APCC PRO.
However, this was only after dedicating several hours over a few nights to running my PEMPRO for polar alignment, and PEC curve generation.
 
    I very strongly urge you to wisely invest in a copy of Ray Gralak’s  PEMPRO – it’s a no-brainer, even if you don’t have APCC, and no matter what other apps you use.
 
    You should  also have kept the APCC, just for ease of using the mount, and more importantly,  keeping an eye on the 3D view  of where it is actually pointed – to avoid unexpected collisions caused by some apps situations. I always keep a mouse button finger resting on the Emergency Stop button, whenever I slew the mount. After one crash, it is probably the best reason I bought APCC.
 
    Anyway, never go on long trip without checking the car, and likewise for Universal sky trips with the scope.
Joe Z.

My first AP mount was a Mach1. I purchased APCC Pro with to use the pointing model. I was not successful in using that with my camera at the time and returned it, and also because SGP by itself met my need for accurate goto's with its auto centering. I am wondering now about unguided tracking with my Planewave 12.5 and AP1200? I now use only dedicated astro cameras, I still use SGP, which is the platesolve program for APPC Pro in any case. My need would be for 10 minute exposures, probably never more than 15 minutes. Should I try APPC Pro to try for unguided tracking with the 1200? I also have not yet purchased Pempro.

George, what do you think of the Baader Vario-Finder for guiding?  I know in 2013 you seemed to have some success with it.  What have seven years of experience taught you?

Guys,

 

Use the Baader scope’s fine focus, not a helical focuser…flexure can enter into the guiding.    The point of the guidescope design was to eliminate all flexure.

Huetech used to sell a nice helical focuser that didn't rotate the camera. You can lock down all of the adjustments with thumb screws so once locked down there is NO flexure or unwanted movement. I have had that setup (with a 50mm guide scope) since about 2005 and it works great with my 152mm and 80mm APO refractors. I have another 70mm guide scope with a longer focal length  and different focuser that I use with both the 152mm APO refractor and a 11" SCT. The trick is to eliminate ALL possible loose/soft connections....once you do you will get great guiding. 

I don't have the part number of that Huetech focuser anymore so can't help there.

I've reviewed most of what you've posted about guiding in this forum, going back two decades.  That's not to say that maybe I haven't missed something important.  In the past I ignored the Advanced Settings in MaxImDL  I never looked at them.  I got what I got.  Having studied your advice, I believe my results have noticeably improved on nights of good seeing.  It's the nights of bad seeing, like the last few nights, that still trouble me.  Fiddling with the Min Move and aggressiveness, I've been able to get good results (= approximately round stars) on NGC 7293, which -- even for me at 33.5 deg N -- is pretty far south.  But guiding on something straight overhead, like M33, has been less successful.  That's where I ordinarily expect the best results.  So I'm still trying to get things worked out on nights of bad seeing.  As we speak, I'm still using the QSI's OAG.  But I may go back to using the Baader Vario-Finder again.  There are always guide stars, and I don't have to recalibrate if I rotate the QSI from landscape to portrait orientation.  But I assume the Min Move has to be increased significantly.
