Re: Upgrade to new keypad version (was RE: [ap-gto] Unguided imaging with Mach2) #Keypad

Roland Christen
 

The new keypad requires a CP4, will not work with the CP3.
In order to take full advantage of all the new keypad features, the CP4 will need the latest software download which is quick and easy to do over the internet.

Roland....I have both a 900 CP3 and 1100 mount with CP4. Once the keypad is updated to this new version will it still work with the CP3 box? Both CP 3 and 4 and hand controller are already updated t the latest version of firmware.

Thanks Ray, I have made note of this.  Since your last comment and my checking of that advanced setting, has been opening and closing properly. 

The code snippet is helpful anyhow as it is another piece of programming know-how to archive. 

I'll be posting a few more questions as we are fine-tuning the system. 

Thanks again,

Re: Questions about APPM

Ray Gralak
 

Hi Bryan,

1. Page 214 of the APPC-Pro manual says "For additional tips and unique ways to use APPM, see the
Advanced Topics section."
I cannot find an Advanced Topics section anywhere in the APCC-Pro manual. Can you point me in the right
direction, please?
That sentence should probably be removed. The idea behind APPM is just to collect data points that can be used to create pointing and tracking rate models.

2. If I generate a PNT file in APPM and then load it into APCC-Pro, is there anyway to revert to the pre-existing
pointing and tracking in order to compare images with and without the model. Just unchecking the 2
Corrections boxes in the Operations section of the Point Model tab does not seem to have an effect.
Unchecking the boxes will change the rate and pointing position. If you look at the values on the tab and the rates sent to the mount, you will see that they change. The tracking rate change can be subtle because the modeling is only a refinement over the already excellent tracking of the mount.

3. Is the pointing model that is loaded into the mount stored in the mount or just in the APPM files, i.e. after
parking, closing APCC-Pro, and shutting down the equipment, then restarting everything, do I have to reload
the model?
APPM creates output files with a PNT file extension. The PNT files essentially store data points APPM captured throughout the sky.

The actual pointing and tracking rate models are created by APCC Pro when APCC Pro loads a PNT file, which automatically happens when APCC Pro starts. You do not need to reload the model by hand but you do need to start APCC Pro to be able to use the pointing/tracking rate modeling. These models are not stored in the mount.

I have a Canon T3i and a 6D.  I went back and checked and you are correct about the 'limitations.'


1. Exposures > 30s = Bulb mode
2. Exposures between 1s and 30s = Manual or Bulb modes
3. Exposures < 1s = Manual mode

The program allows you to track the variation in RA and DEC drift from sidereal in a chosen sky location, and then either set the corrected rate on the mount, or pulse it over time.  So it corrects for drift that a good PA won't correct.  But if you are guiding, I think it is superfluous.

I'm a newbie so it's nice to be able to contribute!

Power Supply Ripple

Fritz K
 

Power Supplies:
The older I get, the lighter I need to travel.  PowerWerx recently came out with a small 'brick' supply rated at 13.5 VDC and 4A continuous, 5.5A intermittent (and with Anderson Power Pole connectors).  As expected, the smaller and lighter the supply, the more AC ripple it has.
With 3 A draw the ripple is ~ 200 mV PTP at several hundred Hz
At 1.5 A draw the ripple drops to ~ 140 mV PTP.

By comparison, my old Pyramid 13.8 VDC, 5A supply yields:
Draw = 3A, ripple = ~25 mV PTP, 60 Hz
Draw = 1.5A, ripple =~ 5 mV PTP.

So:  How much ripple can the CP4 handle?
(I only slew at 600X and at temperatures no colder than the high 30's F.  I expect the 4A continuous is plenty for my Mach 1 and AP1100.)

Thanks,
fritz k

I found this in the MaxIm user guide: "ASCOM Direct connects to an ASCOM
telescope driver, and uses the PulseGuide method to send autoguider
commands to the telescope."

I configured MaxIm to use ASCOM Direct with my AP1200, and disconnected
the ST-4 guide cable. It works great! Now I have one fewer cable and two
fewer connectors to worry about.

It's built into MaxIm, and no other program is needed. Search your MaxIm

Re: Invalid ISO error when running APPM to SGPro PlateSolve

Joseph Beyer
 

Dale,

I can only speak for Nikons but I believe it is dependent on the model of camera.  The different exposure modes on my D7200 are accessed by turning a mode selector on top of the camera so it's a mechanical selection.  The exposure modes with the D800 are accessed using a single switch on top and toggling through the different modes using one of the wheels on the camera.  I use at least one piece of software that will allow me to change between the different modes from the computer screen.  From memory I thought Bryan was using a D810 which would have the same controls as the D800.

Hi, Bryan,

This is a timely topic as I have just finished doing a renovation of the Canon driver in NINA and have learned and been reminded of the peculiarities of operating Canons via the Canon-supplied EDSDK library. Nikons handles its cameras in similar ways.

First, I think you must be mistaken about the Manual mode and exposures. Canon does not allow software to set the camera exposure mode - the mode that is set by the physical dial on the camera. One can retrieve the camera's currently set mode as well as a list of modes that are supported by the camera, but a mode change cannot be set via software. The user has to physically change the mode dial to switch modes. This is important to note because:

Second, Manual mode allows for exposure lengths to be specified up to, but not over, 30 seconds. For exposure times over 30 seconds, the camera must be set to Bulb mode. Bulb mode can make exposures under 30 seconds, but it does not support making exposures under 1 second in length. So, to summarize:

1. Exposures > 30s = Bulb mode
2. Exposures between 1s and 30s = Manual or Bulb modes
3. Exposures < 1s = Manual mode

There are no exceptions to this for any of Canon's DSLR line, and both experience and the EDSDK documentation from Canon make this clear.

On Canon cameras where Bulb mode is not selectable on the dial (xxxD/Rebel cameras and most, if not all, xxD cameras), one must set the mode to Manual and turn the shutter speed selection wheel until the shutter speed is reflected as "BULB" on the rear display. This is the only case where Bulb mode can be specified programmatically as it is considered to be a shutter speed rather than a mode setting on those camera models.

Canon xxxD cameras of the 400D (Rebel XTi) and older do not support remote shooting in bulb mode, and require an external shutter trigger such as the Shoestring DSUSB.

Looking at the 6D's manual, it does feature a mode selection dial with (B)ulb mode. This means that the camera must be in Bulb mode for exposures > 30s in length, and can be in either (M)anual or (B)ulb modes for exposures between 1s and 30s in length, inclusive. In an astrophotography context, since the usual exposure is going to be over 1s and usually more than 30s, it is typical practice to leave the camera in Bulb mode.

I read that section a few times this afternoon, but it is not completely accurate. For instance my Nikon is not in the list of long exposure cameras yet it didn't need a DSUSB for long exposures in testing I did this afternoon.

here is the section from the SGP manual on cameras that "explained" it
https://www.mainsequencesoftware.com/Content/SGPHelp/Cameras.html#CanonCameras


Canon Cameras - There are many features in Sequence Generator Pro that are unique to Canon Cameras and require special consideration when using Sequence Generator Pro. Such as:

LiveView - Cameras that support LiveView will have the option to turn on LiveView in the Frame And Focus Module
Bulb vs Manual Mode - If your camera has a dedicated "Bulb" mode on the Mode Dial then you should use this mode for any exposure over 1 second. Also exposures under 1 second are not reliable when using Bulb mode so if you require reliably timed short exposures then you should switch the camera to Manual. For cameras that DO NOT have a Bulb option on the Mode Dial these options do not apply.
If your camera supports "Auto Rotate", you should turn this off while you are using the camera for astro-imaging (the mount will hold the camera in all sorts of odd positions and possibly create images that are difficult to stack without manual manipulation):



For NikonNikon Cameras


When connecting a Nikon camera, it is normally as simple as connecting the camera via USB and, if needed, with a Nikon shoestring adapter. When only one camera is connected you may simply click the "Connect" button on the sequence form. If multiple Nikon cameras are connected, use the options dialog (below) to tell SGPro to which camera you would like to connect.


Some Nikon cameras require a shoestring DSUSB adapter to exposures longer than 30 seconds. Other, newer, Nikon cameras can take long exposures without an adapter (via direct USB connection).


Long exposure ready (bulb mode) cameras: D810, D810A, D800, D750, D800E, D7100, D7200, D5200, D600, D610, D5, D500, D5300, D5500, D4, D4S, Df


If your Nikon camera is not in the list above, you will require a DSUSB adapter.



Image Data Formats:
Single Image (CFA FITS): Stores the CFA (Nikon Filter Array) data in a 2 dimension FITS file. The data remains Bayered (mosaiced).
RAW Image (NEF): Stores the native Nikon Raw format
RAW + FITS: Stores both of the formats above
AF Binning: DSLR cameras can sometimes have difficulty determining star centroid on AF frames (due to the bayer matrix). If you are having difficulty obtaining a \"V\" curve with AF, try experimenting with different software binning levels.


Note: RAW Images will not contain meta data found in the FITS format.
