I don't know if it's better/same, but USB is definitely easier for us

Hello Ray,

No, I have not seen that referenced anywhere. How do I do that?

Thanks,

Have you tried the USB port?

Connecting directly to a device with an Ethernet cable usually requires that you set up your laptop to use APIPA (Automatic Private IP addressing 169.254.0.0-169.254.255.255).

Have you done that?

Sometimes you have to hit the refresh button a few times to get it to locate it. 

If that is still not working, it is possible the cable is faulty, or the network interface is older and wont support a connection without the use of a crossover cable. That I would doubt, but something to consider.

In APCC you can have the software search the machine to locate the correct interface and IP address. Have you used that utility? The + sign magnifier glass is what I am talking about:

I doubt that it is the CP4 that's the problem. I have alerted our software guys and they should be able to help you out.

I also sometimes cannot connect my laptop to my scope via Ethernet. In some cases cycling power on the CP4 allows the laptop to "find" the new connection and then i can connect. It seems the software in my laptop gives up after a couple of tries and won't find any Ethernet connections until i do the power cycle.

Hello all,
I am in the process of setting up a new 1100. I have tried to connect to the CP4 with APCC pro with no luck. This is with a direct Ethernet connection between computer and CP4.
I have tried connecting with Ethernet via web browser and can't connect to the CP4. I used the math method of appendix C of the CP4 manual to determine the address for the CP4.
I also used a AP provided web site where you enter the serial # and it gives you the address for the box. Both methods give the same address.
I have used multiple Ethernet cables. All equipment is new. I am now thinking that possibly the new CP4 is defective.
Hopefully someone can help me out. Thanks, Kenneth Duncan

Re: Storage box for the Mach2 mount

M Hambrick
 

Here is what I put together for my counterweights using the short Ridgid toolboxes originally suggested by Tony (a.k.a. Harley Davidson). I need two cases to hold the counterweights for my 1100 Mount; one holds two 18 pound counterweights with room for a third. The other holds the counterweight shaft, an 18 pound counterweight, and a 10 pound counterweight. The foam in the lids is 2-inch thick. There are two layers of foam in the main part of the case. The base layer is 1-inch thick. On top of that is a 2-inch thick layer with the cutouts for the counterweights and shaft..

Both cases are heavy. I set up and take down my mount every time. I have found that if I use proper lifting techniques I can carry all of the counterweights to the mount in one trip. Carrying them piecemeal (one in each hand) requires three trips, so these cases are big timesavers when I am setting up.

The foam is closed cell high density (1.7 lb) foam. I think the grey foam is actually denser, so if you can get that it is better.

For my TEC 140 + imaging train (a pretty long imaging setup), I had to add the 8" extension to prevent the camera colliding with the pier legs, so whether you need the extension really depends on your set-up.


Re: APPM Models

Lee Dodge
 

Thanks for the reply Dale.  Using data from https://www.mide.com/air-pressure-at-altitude-calculator, I come up with a correlation at my altitude of P(mbar) = BARO (inHg) x 3.5599 x (T(C) +273.15)^0.3409.  I am just trying to verify that weather stations that report barometric pressure and temperature are being corrected for altitude and temperature for use in APPM model inputs, and that my approach is reasonable.

Using this barometric pressure at my altitude would be nonsense, as I compute the absolute pressure at my altitude and a temperature of -11 C (today's temp.) to be 725.3 mbar. The difference between the barometric pressure and the actual absolute pressure at my location is that the barometric pressure is always converted to some sea level equivalent, and regardless of how high you go, the barometric pressure is always around 1013 mbar. If the model is looking for barometric pressure, then it must be labeled barometric pressure rather than pressure, and if it is really looking for pressure, then how are folks getting that from the local weather report. Which pressure is it looking for?
I think it's pretty obvious and well-understood that the local air pressure is what goes there. How one gets that number is up to their discretion and judgement. For some, the reports given by a weather service are sufficient as those are collected from both official and private weather stations and from local airport weather equipment can be quite accurate enough. Others use local devices. I have a small Arduino-based project the size of a stick of gum that includes a BMP80 air pressure chip and an ASCOM driver that can read it. Yet others have their own weather stations and enter the data either manually or via ASCOM driver, if their weather station has an ASCOM driver that can talk to it. If you find that you need to take a local reading and modify it for your altitude, and it works for you, then it works for you.

mbar is equivalent to the SI unit for air pressure, hectopascals (hPa). The ASCOM ObservingConditions driver specification says that all its various units are SI units, and the astronomy world in general deals in SI units for all measurements. I'm not sure why there needs to be any consternation here.

If you use it for imaging, then no extension is needed. If you want to use it visually then you will want to raise it up with an extension piece.

Hello Everyone,

Anyone using the 6" Eagle adjustable folding pier? What scope do you have? and whether you have a  4" or 8" extension? 

I'm expecting my Mach2GTO to arrive soon next month. and I need to order the extension part if required.  I currently own C11 and Televue NP101is Telescopes. I also plan to purchase C14 Edge HD in near future.

Thanks & Clear Skies,

Re: Mach2GTO 6" Eagle Adjustable Folding Pier #Mach2GTO

Terri Zittritsch
 

I am using the Eagle pier, very happy with it.   I use an 8" extension as well.      I have numerous scopes I use with it, the heaviest being either a TEC140 or Edge 11" scope, not sure which is heavier.   I suspect the Edge.    I originally purchased an Avalon T-Pod, but found that a normal tripod with fixed leg spread doesn't allow the same kind of dynamics and stability that the Eagle provides.    The Eagle, with its adjustable leg spread, allows for a pier-like functionality when used with an extension or not.   I use a maximum spread before leveling and an 8" extension to keep height.   I find it very stable no matter the scope size I've used.   I've also done a dual setup with TEC140 plus Stowaway, and it balances nicely and very stable.     What I found with the T-Pod, with its fixed leg spread, is that with an extension to get good clearance I had to shorten the legs else the tripod was far too high for me.   When the legs are shorter, the footprint is proportionally smaller and less stable.    To get the stability on a fixed leg spread tripod I had to extend the legs to the level where it isn't practical to use an extension (I'm tall but  not that tall).   I could not find a level that I was happy at with the T-POD.   Now I use the TPOD with a 6" discmount for visual.    For A-P, you can't beat the Eagle.    The other thing I found much easier with the Eagle is leveling.    By loosening one leg at a time and pushing against that side of the pier, I could easily provide fine adjustment to the level and the single knob tightens easily and solidly.

Re: Storage box for the Mach2 mount

I use a Maxcase 540.
It is a Peli like case produced in Italy, very high quality and right price.
I have changed the original foam with the same material used by AP for shipping, very easy to cut.
I keep the dovetail and bar separated to limit the weight.
