I used just the 160 for this one. I'm using the other one to test some accessories.

That’s a beautiful image. Ha luminance worked a treat to tame down the noisy channels.

Did you use both telescopes to collect this data or only one?

Apologies Mike, I meant to reply to you before now. I looked at your website, and all I can say is WOW. Very impressive. I particularly like your use of a microcontroller. I see a lot of use for mc's like the Arduino and sbc's like the Raspberry Pi in remote observing.

Question for you, a little off topic I guess, but if your observatory was not 300 feet from your house but about 80 miles, would you feel confident in its operation? Assuming you had reliable comms between the two naturally.

Yes, indeed. It certainly is not unheard of to have a mobile app mimicking a piece of hardware. I guess the user base and other connectivity options in this case hasn't warranted it.

Then don't use the features you don't care about in the planetarium app. And BTW, the keypad has features the AP V2 ASCOM driver does not have, like an object catalog.
Yes, of course, that is obvious. And I do appreciate your other solutions. I just wanted to determine if such an app existed.

I may look at developing one now that I have some free time, observing catalog included :)

Thanks

Re: Find my CP4!!! How annoying!

Will do.

I also got a new router in the last few days, and this router does not show the IP address of the mount until it is connected. That is strange since my old one did.
I never had the issue before.
Can one put a static IP into the CP4?  I see no options to do so or is it in the web interface?
Tom


Re: Find my CP4!!! How annoying!

Pete Mumbower
 

Great to hear you got the new address. If you can log into your router, you can lock the CP4 to that address via a "reserve" function. Basically the router will only give that IP address to the CP4 mac address.

Pete


Re: Find my CP4!!! How annoying!

Tom Blahovici
 

Thank you guys so much!  The scanner worked.  I had been entering the IP address manually and gave up at 192.168.1.155...it was 157 lol...
This is nuts though.  The tool should be in the APPC or astro-physics folder.  One should not have to go through so many hoops to get this.
Anyways, you guys saved my weekend.
I'm going to write a utility to do this myself and share it here if I can.
Thanks again!!!


Re: Find my CP4!!! How annoying!

Pete Mumbower
 

If you have not tried it yet I would reboot the router, wait a couple of minutes, then reboot the CP4. The DHCP function in routers sometime puke out and will stop handing out IP addresses which the CP4 should be requesting on each power up.

Pete


Re: Find my CP4!!! How annoying!

Hi Tom,

Three things I would try:

1) You could use an IP scanner utility (such as https://www.advanced-ip-scanner.com/) and scan the entire subnet (use the 3 first bytes of your computer's IP address + .0/24. e.g. if your IP is 192.168.0.16, type-in 192.168.0.0/24 in the search bar of the scanner app). If your CP4 actually has an IP address in the same subnet as your computer, it should find and list it.

2) Use the following math (from the CP4 manual) to calculate the default IP address and connect directly to your CP4 through an ethernet cable. Then change the IP address of your network card to 169.254.0.1 with subnet mask 255.255.0.0 :


3) If you still can't find it, use the IP scanner app again to scan the entire 169.254.0.0/16 subnet. That could take a couple of minutes as it  needs to go through the 65,000+ possible adresses, but should find it in the end.

Hope this helps...

Sébastien

Well, after a power failure I go out to use my scope and the IP address is changed.  Looking through my router, there is no indication of it.
So, read the manual and I have to download a JAVA applet.
It needs a user name and password!!!
Any alternatives or do I have to wait until Monday for the shop to open?
First time in my life I have seen a network interface with no possibility to do anything except guess.

Tom,

Sometimes router have a hard time showing new Ethernet clients. A utility that can help in this task is Advanced IP Scanner. It will give all the clients on the network served by the router and if the CP4 is on it, it will find it.

Is using a USB cable out of the question?

Cheers,

Luca

Re: Flexure or tracking? (Another "cold night" from northern Indiana)

Roland Christen
 

When we had the problem in Chile I improvised by using a frame with the fans mounted with 4 rubber bands for each fan. That solved the problem and allowed us to do some imaging before new fans were installed.

An update to this...last night I had about 4hrs of clear sky and in order to test the theory about the fans causing the elongated stars I unplugged the fan from the camera.  It was still plenty cold enough to reach my -10C set point without issue.  Long story short, every single sub that came in had perfectly round stars.  The difference seems obvious to me.  With the fan operating as normal about 3/5 subs came in with elongated stars.  With the fan disconnected every sub was perfect.  

The problem is that I'm not exactly sure what to do about it.  Noctua is generally regarded as the best brand for silent and vibration free fans, but they do not make the size I need (50mm).  I did buy some fans that look better than the stock ones I have, and I'm going to try some Noctua silicone rubber mounting things that are supposed to help isolate the fan from the case (if they fit on the camera). We'll see how that goes. 

In any event, this is no longer an Astro-Physics related discussion so I'll look elsewhere.
