Here is my latest image from November. This was a target that I avoided due to
halos on Alnatak. But after finally getting filters that do not halo (Astrodon
Gen2) I was able to capture it.

Hope you like it.

Re: Confusion After Installing the "S" Chip

Check out the link below from their website. It says Q or earlier. It also notes that the keypad info will not change so date time location is still in there, but that info has to be downloaded to the servo firmware for it to be reinitialized into the mount.

Hope this helps.

Hello anyone who can help.

I have just received and installed my "S" chip replacing one which is version "O".

There seems to be a contradiction in the two instructions sheets received with the chip. The one titled "Installing New ROM Chip into GTO Control Box-Model GTOCP3, Chip Version "R" and later", in the last paragraph with the subheading titled "After the ROM chip replacement-Versions "R" and later", it says "If your previous ROM chip was version "Q" or earlier, you must perform a full initialization on your first power-up, and you will also need to redo the mount's PEM. Etc."

In the second sheet titled "Your first observing session" it says in the next to last paragraph titled "After a ROM chip replacement-GTOCP3-Version Q and earlier", "Install your new chip and proceed normally as if nothing had changed. Etc."

I had the "O" chip, do I need to do an initialization on first start up and redo PEM or not?

Re: Guide system suggestions

Jeff Crilly
 

I'll second the "OAG is the only way to go".

However, to start, I would suggest doing ~unguided~ imaging w/ the C11 and see how that goes. You got nothing to lose, and it will be a good exercise.

Here's some thoughts based on my experience with long FL imaging...

1) at 2800mm i suspect you will be "chasing the seeing".

2) Additionally focus is critical w/ temperature change if the tube is aluminum.

3) As for mirror flop -- i think this might depend on which C11 you have.. the later models have mirror locks and carbon tubes, iirc.

Hence I would suggest a OAG w/ reducer... and depending on the C11 focuser, add an aftermarket between the OTA and the OAG.

I've been using a meade 12" "RC" aka "ACF" OTA on an AP1200. (with various cameras: CCD and DSLR).

I started out simple -- piggyback guidescope, using the moving mirror focuser. No go.

Upgraded to lumicon Giant easy guider w/ reducer. Better, but focuser / mirror slop was still ridiculous..

Upgraded to Clement 3" focuser. This worked.

It is indeed a challenge to find guidestars, etc, with the OAG.

(I have more fun widefield, or with apo refractors (Tak, sadly no AP refractors in the house) at about 1000mm.)

Btw, as for "guidecamera + guidescope" combos (assuming imaging with a refractor)...
I am using a 400mm camera lens + meade-dsi-pro (mono). Mainly cuz this was almost zero cost for me.

Hi Dan,

Would you be tempted to put a Takahashi FSQ85 atop your C11 with something like an Orion StarShoot camera? You can guide your C11 with this setup for narrow fields; or do widefield imaging with the FSQ, letting the mount do unguided tracking.

Hi guys,

I'm an owner of Mach1GTO.
I'm very interested in APCC but I don't fully understand what exactly it is.

Is APCC an application using the AP ASCOM driver or some sort of driver?

I'm using Sequence Generator Pro and several other planetarium software such as SkyTools and Cartes Du Ciel for image capture, plate solving and syncing etc. These software uses the ASCOM driver to move the mount and send the Recal command.

For example I do an initial Recal with Cartes Du Ciel for a star and use Sequence Generator Pro to do plate solving to go to the target to match the image from the previous night or go back to the target after re-focusing. Sequence Generator Pro do the plate solving using PinPoint or Elbrus.

What would be the work flow if I use the plate solving feature of the APCC?
Can APCC work with the other software using the ASCOM driver (other software sending the RECAL command)?

My setup is not a permanent setup.

Re: seeing, and optimum guiding

roywellington
 

Morten,

Please find a spreadsheet in the Stark-Labs yahoo group called "Guiding Worksheet". The spreadsheet was designed to test the effects of the PHD parameters Aggressiveness and Hysteresis. I got an estimate of Seeing from the PHD log which is likely exposure dependent. The spreadsheet does not directly address your question but I hope you find some value nonetheless.

I usually use a guide camera exposure setting of four seconds. I feel I must reach for "Star Mass" at least as much as minimizing fluctuations from seeing.

I put a copy of the spreadsheet at http://goo.gl/sc1SC

One of the problems autoguiding AP mounts is that the corrections needed are small compared to the fluctuations of the guider centroid caused by seeing, at least in my area. One way to reduce centroid vatiation is to increase guider exposure time. In order to optimize the parameters without wasting preciuos observation time, I need an empirical relationship between exposure time and centroid vatiation.
If some of you already have made that exercise I would very much appreciate the conclusion, and/or the data. I.e. phd og maxim guidelog files with different exposure times for the guider.

Re: Guide system suggestions

Kent Kirkley
 

Off axis guider (OAG) is the only successful way to go.


At 2800mm differential flexure will, if not sooner, then later, rear its ugly head.
Unless you can lock the primary mirror in the C11 there will also be 'mirror flop'..
which is the mirror moving on its 'thimbell' as the the mount tracks across the sky.
All of this will result in trailed images..and be very frustrating.


Now, since you will be trying to use a Canon 60Da....your exposures will not be
very long, probably shorter than 5 minutes...and a separate guide scope might work.

Hi Jim:

that I just used dated 9/5/12 for Windows 7 and 8:

http://www.tripplite.com/en/support/downloads/downloads-by-model.cfm?txtKeyword=USA-19HS

I don't know if you can update the driver while the Keyspan is still
attached. It seems like you could eject the keyspan in Windows, update the
driver, then restart the computer?
