Re: Off Topic-NUC Computer
Steve Reilly
I started this thread back in July and here it is September and I’ve finally built the deck and have the dome almost finished. I need to install the motors and controls but I’m back on the NUC again as the ROR computer seems to have an issue with the USB ports not keeping the SX guide camera active. I was headed this way anyhow so what I’ve found is listed below and could use some feedback from those using NUCs o run their systems.
Shared Product: Industrial Fanless Intel Whiskey Lake NUC With Dual LAN Shared Configuration Memory (Select QTY)
Does this look to be capable enough to do the job without being underpowered? The size of these M2.2260 drives are small and expensive but my thought was to use an external 1TB hard drive located in my ROR control room connected by an USB2 active extension cable. The NUC will be mounted on the pier close but not so close it could be in contact with the mount/telescope. Cabling would be minimized by using a powered USB hub on the telescope for cameras, focuser, dew controller, rotator, and whatever else comes up. It has guided well with the cables as is but this should minimize cabling substantially.
I’d appreciate and thoughts/concerns/comments you before I order. I’m way more use to building desktop systems for observatories and this will be the 1st NUC.

Hey Gang,
In the process of setting up a 12’ Astro Haven dome and moving my 12.5” RC and AP1200 mount from the ROR to the dome. In the process I’m contemplating replacing the observatory computer with a NUC to both shorten the cabling and have a more compact unit. I counted the ports as the computer is now configured and have the following needs:
Serial ports=7 I have a StarTech ICUSB23241 4 Port Industrial USB to RS232 Serial Hub but that still leaves 3 needed ports (focuser, rotator, AP1200 backup, Dew Heater Controller, Flat Panel, Boltwood, and dome controls)
USB ports = 4 including the one for the Serial Hub, Guider camera, Main Camera, mouse and keyboard
Network minimum=1 then use the 8 port Gigabit switch I have ( 1 AP1200, 1 Computer network, onsite pan cameras (3), etc.)
Display port=1 HDMI or DVI
Anticipating fiber optic internet connections in the next month or so I also ran Cat6 cabling for network switch and mount.
So with that in mind the ports, mainly serial are what have me second guessing the NUC. I have, almost ready to ship out, a OnLogic NUC for a friends SRO system but that’s way more then I care to spend although it has all the necessary ports to hook everything up directly with hubs and so on. So based on this what would be a reasonable budget for what I’m looking for in a quality, reliable NUC? Even if I use the existing desktop computer I have now it will be without all the extender cables I’m using now as the computer is in the warm room 20’ away but the idea of a sealed fanless computer really appeals to me for this type of usage. Hence I’m looking for ideas to explore while this project continues, in of course, the hottest time of the year.
Thanks,
Steve

Re: Unguided dumbbell stars insights
Roland Christen
Just run a guide graph in PHD2 with guide corrections turned off. Run it for 15 or 20 minutes so you can see the tracking rate over several worm cycles. Then you will know what you are dealing with. These older mounts sometimes had small subharmonics which roll thru at different gear angles and do not respond to PE correction. It's probably just a few arc seconds +- but shows up easily on any long exposures.
To do proper trouble shooting requires digging a bit deeper. Just posting a picture with eggy stars only shows the problem, but doesn't show the why.

Re: Transfer of APCC Pro license with sale of a mount?
Chris White
On the APCC FAQ Page:
I just sold my mount and the new owner would like to use APCC. May I transfer the license? Note: According to the license agreement for all licenses issued prior to 08-16-21, transfers were not allowed. We are providing the ability to transfer these licenses as a courtesy and they are subject to our approval.

Transfer of APCC Pro license with sale of a mount?
Patrick Spencer
There was a thread recently that suggested AP was looking into changing the licensing terms to allow transfer of an APCC Pro license with the sale of a mount. Was that change ever implemented? I'm getting ready to list my Mach1 for sale, and I no longer need that APCC Pro license because I got another license with my 1100GTO-AEL. I want to make sure I don't give bad information to potential buyers.
Thanks, Patrick Spencer

Re: Mach2 RA Judder
Here is a single short 20s sub showing the elongated stars. A sub from 5s to 60s showed the same shape. At first I thought it may have been vibration in the camera fan, but it made no difference with the cooling fan on or off and it is in the exact direction of RA.

Mach2 RA Judder
An issue with my RA axis has developed with my Mach 2. Everything starts off fine and then I begin to notice egg shaped stars across my whole image and are elongated in the same direction as RA. It does not matter if I expose for 2 secs or 30 secs, the shape is the same. Tonight I was imaging saturn and the same issue suddenly started. In the video below you can see saturn juddering back and forth while the mount is sidereal tracking. The last few seconds in the video, I slew in RA at 1x and you can see it smoothen out. I am not using tracking correction in APCC, in fact if I don't use APCC and the ASCOM driver only I get the same results. Counterweights and shaft are tight. I have an AP 18lb weight near the top of the shaft and a 10lb weight about halfway down. The issue is happening frequently but is intermittent.

Re: High Res Planetary imaging with the AP1100
Rouz
Daniel,
Thank you, glad you liked them. Yes, that technique is a very good way of doing it, probably better than RGB as you said. I also tried many combinations like RB only to make synthetic green, using IR as R or even IR-RGB and RG610 long pass. It amazing you can do some much to squeeze out the most possible resolution. I actually had an 18" f/15 classical cassegrain order but cancelled it and decided to pursuit deep sky imaging instead. Overall a very additive hobby we have :) Clear Skies, Rouz

Re: High Res Planetary imaging with the AP1100
Rouz, These are truly amazing images indeed. Now, as per your filter sequence, you write: From: Rouz Over the time I have modified this classic sequence " Mine are as follows: RGB-BGR-RGB-BGR and so on. Why? Two reasons: first, for derotation an RGB-BGR sequence provides an RGB set with two images per filter, where the three monochrome images end up at approximately the same time. This avoids limb artifacts. And if something is bad in, say, the RGB run in this doublet, well, just take the following BGR-RGB group to get the same result. The second reason is that it saves two filter changes per sequence. This is a plus for me since my filter whell is manual ;-) All my compliments again!

Re: Keypad Recalibrate with CP5/Mach2
In the PDF:
toggle quoted messageShow quoted text
Recalibrate Recalibrate is used to correct the calibration of the mount if an object that you just slewed to does not appear in the center of the field. Recalibrate can be used even when the object is past the meridian and the telescope is below the mount. Simply press the RECAL and NEXT> buttons simultaneously to recalibrate on your object. The keypad will beep to confirm that the command has been issued. In the GTOCP4/5, you can send the mount to an object via a GoTo slew using an external planetarium program, then center and recalibrate using the keypad. NOTE: You can only use the recalibration option if the keypad has the target object in its memory, i.e. you just gave a slew command via the keypad or external program and the keypad already knows it should be at that object. You CANNOT use this option if you manually move the telescope to another position, since the keypad would have no way of knowing what that object is. Grüsse Konstantin v.

Keypad Recalibrate with CP5/Mach2
I have an updated keypad with my Mach2 but for the life of me I can't figure out how to get recalibrate to work. The only Keypad manual I can find is the one from version 4.19.3 and a LOT has changed since then. Am I missing something?? Thanks!
