Really pretty image Tom! I'm just learning PI myself and have the same challenges with the image going soft during the noise reduction. Steve's comments are where I'd go too - a tad soft, maybe back off the NR or do it in PS while you refine your PI process.

Hi all,
Been a long time since I posted here. Been way too busy getting used to
retirement and getting set up at Sierra Remote Observatory. Also

some levels tweaking and getting it ready for the web. While I like the
overall look and think it is a pretty picture, I am a bit worried that I
may have gone to far on the noise reduction, maybe it is too smooth. You

be very interested in comments (I have a very thick skin).

Let me know what you all think:

Tom,

 

Very nice image with a great deal of detail. Smoothing is a bit strong for my taste. Which process did you use for smoothing/noise reduction? Sometimes I’ll take my image into PS and create a separate layer and use a mask to just apply the noise reduction. This can also be done in PI. Make a star mask and try using it both inverted and not to see what is being reduced. This is a great image though.

Re: USB to Serial cable

That's correct assuming you want to attach USB-to-Serial adapter directly to serial port of CP3.

Qestion about Meridian mapping and delay in APCC

Wayne Hixson
 

I finished my horizon mapping and meridian mapping today. I enabled both and set the delay to 6 hours to test. I did a GOTO Betelgeuse and it went there on the east side with counterweights up as expected. I then tried to change the delay to 3 hours. I clicked Set and the delay turned briefly to 3 hours then back to 5.98 hours and it seems to be stuck there no matter what I try set it to or clear it. I don't understand what it's telling me


Re: USB to Serial cable

I may be wrong whether the electrical pins are female but it uses nuts instead of screws and won't be able to fasten to serial connector of CP3.

Be careful when you choose the adapter and check for male/female pins and how it's connected. The one you link appears to use female pins and uses female nuts instead of male screws. This will not be able to attach to serial port of CP3.

The one you link will not be able to connect to serial port of CP3 that adapter uses nuts instead of screws to fasten to serial connector of CP3. Also make sure the electrical pins are male.

Hi Joel,

That other black box is Starlight Instruments/Optec Focus Boss II focus hub to control Handy Stepper Motor (HSM). This has an ethernet port as alternative to Serial. I have tested ethernet and it works. I am currently using the Serial port (via US-to-Serial adapter) because the way I setup my cable management, it is nicer.

The FTDI adapter you linked looks good to me. Made by the same company as one of mine.

Hi Joel,

There are many good FTDI products and I have two different brands and they work very well:

http://www.amazon.com/gp/product/B00EDU4G0I?psc=1&redirect=true&ref_=oh_aui_detailpage_o03_s00


I am currently using the second link. See how I use it at:

Re: CP4 power connector

topboxman
 

I am also curious about the polarity of the power connector on CP4 as well. I received the power connector from Mouser.com and I already soldered the wires to the connector but the other end of the cable that connects to the battery is still open.

Thanks,
Peter

Resurrecting this thread, I am soon taking possession of a Mach1GTO and plan to upgrade to CP4.  I have an observatory and power everything via household AC power.  I don't relish the idea of needing a bulky 13.8v AC to DC converter, or needing to take that along to dark sky sites that use AC power as well.  

With other mounts I've simply used a good quality AC power supply that outputs 12v 5a DC power which are readily available with standard 5.5/2.1mm power tips.  

I'm comfortable wiring powerpoles, but what I don't know is with the new CP4 power connector I don't know which pin is positive and which is negative.

Is it possible to get an AC powersupply with this power tip?

Re: Bug between Hand Controller and APCC on Park 3 position.

Ray Gralak
 

Hi Wayne,

I have the latest 4.19.2 firmware. I've found that when I start with the hand
controller and select my location and resume from previous, then end up parking in
Park 3, when I then open in APCC and look at the 3D view, the scope is upside
down; that is pointing north but with the scope under the pier and the
counterweights up. I end up parking to current position then unparking from Park
3,then is seems all is well. Anyone else run into this?
If you are not initializing from APCC then you may need to Re-Sync the 3D view at least once. Have you tried that?

Re: Using Ethernet in the Field Questions.

Ron Wodaski <rwodaski@...>
 

Your USB to Ethernet device would be one way to add wired Ethernet to your computer.

The basic design would be to run wired Ethernet from your existing router (or any Ethernet switch that is closer to your observing location) to a switch, and then to connect your devices to it. As long as the wired and wireless (wifi) networks have the same IP range (e.g., 192.168.xxx.xxx), they will all talk to each other. You would not need the USB to Ethernet adapter if your laptop has wireless in this arrangement - it would talk via wireless to the router, and wired Ethernet between router and observatory would allow the equipment on the observatory switch to talk to wireless devices and vice versa.

To make a normally wired device wireless, you typically want a box that communicates over wireless, but that also has a wired socket that can connect to a single device (not to a switch, typically). You run wired from device to said box, then the box, when powered up, uses wireless to connect the wired device. I typically use an Apple Airport Express for this function.

Thanks Ron, you mean add an Ethernet port to the laptop? That actually would probably mean a new laptop. Which is ok if needed. Could I then add a switch to go to the devices? What I don't know is having simultaneous connections to the equipment and to my WiFi for Internet access.

On the wifi front, are there devices to connect wirelessly to my computer and wired to the devices? I just don't know enough about networking.

Thanks again

Wayne
