The auto-dew feature on the UPBv2 is a bit ham-fisted at the moment, but it will get some improvements according to Evan of Pegasus.

I was also contemplating a Dew Buster as well before getting this, with the Dew Buster's auto-dew logic and that it places thermocouples up where the dew straps are to take the OTA temperatures and base its power level on that. The UPBv2 is different in that it has its own temperature+humidity sensor but it's not near the optics (although you can place it wherever its length of cable allows you); it's very much reflective of the ambient air around the OTA, not the temperature /of/ the OTA.

But really, in the end that doesn't seem to matter. The UPBv2 seems to ramp up the dew strap power output early enough such that dewing has never been a problem. Like I mentioned before, I'll set my rig up in the afternoon and just let it chill until it's time to start imaging later in the night. I just set the auto-dew to on and go about my day, have dinner, play with the kid, wrestle him to bed, clean up, and finally when it's astro-dark and I can turn my attention back to imaging, the dew heaters are already on with power output in accordance with the how close ambient temperature is to converging with the dewpoint.

I say it's ham-fisted in that it's very coarse in its incremental ramp up, and it seems sometimes that it will ramp up too fast and drive the dew straps at higher outputs that is really necessary for the conditions. One tactic is to let it auto-dew early in the evening, then turn the feature off and manually set the power output for each strap in accordance with your own intuition. The next version of the UPBv2 control app will have a new "Auto-Dew Aggressiveness" setting which will let you control this more. It's already available in an update to their smaller PPA product, and Evan at Pegasus says that it'll appear in a UPBv2 update soon as well. For what it's worth, I use Dew-Not and Kendrick straps, and the dewing levels I experience are typical of what you'd find in a mid-Atlantic suburban environment.

guiding min/max question

richard payne
 

Hi, I have a simple question, first I have a 11000 mount, guiding with a 50mm f5 Borg
and a Starlight Express Costar.  Using either the Sky X or Maxim   for camera control,
if anyone is using something close what are your min/ max settings and aggressive #'s?
I understand seeing affects everything just curious to what others are using.  I have tried
several different numbers .02/.2 min/ max to higher numbers. Thanks
Richard

Hi Axel, you should be able to see it here:

https://drive.google.com/file/d/1jQXRltbI9mJDYR5YmSh3fTPXKPKJgC7X/view?usp=drivesdk

I've had the MDS dovetail on the top of all of my scopes for years, it's light and it allows me to add my larger guide scope, with MDS clamps, to any scope.   With the advent of smaller guidescopes and small pixel guide cameras, I use a small, focuser mounted,  60mm guidescope for many of the smaller scopes now, but still have a need for the larger guide scope, which keeps me from implementing a general solution of all top mounted accessories.  I really want '1' thing I can move from scope to scope.
This plate uses MDS clamps bolted to a piece of aluminum (1/8") which is overkill and adds about 15 ounces.    The bend in the plate is limited to my  largest diameter scope which is what it's on now, an 11" Edge.   On the plate are an 8 position powerpole strip, a focus boss ii (rugged but heavy), a reliable usb hub and a dew buster controller.     After reading Dale's post, I may take the plunge and give Pegasus a try.   Being an EE and 'tinkerer', it's kind of in my DNA.    The current setup is very reliable for me.. so reliability is important.    With the through mount cabling on the Mach2, the cables on the tele don't bother me so much.    This setup with the 11" is for planetary imaging and not deep sky imaging.. so nothing is really tied down very neatly right now and as long as it doesn't drag, i don't worry because I change scopes pretty often.

Hi William,

I'm going to check out VHB.

Also, I ended up buying a a 3D plate from Joel. He had one in stock with the right hole locations. The plate it is light, strong enough to support my gear and highly affordable ($18). In addition, he sells thumb screws 1/4-20 for $2 to secure the plate to your rings.

Now, I just need to see when I can afford a UPBv2?

Best,
Alex

Hah! I used 3M VHB (very high bonding)! That suckah ain’t going nowhere! After all, that’s what they use to attach architectural panels to the outside of skyscrapers!

 VHB™ Architectural Panel Tapes are commonly used in architectural panel applications. It reliably bonds a variety of materials with strength and speed for permanent applications. 3M™ VHB™ Architectural Panel Tapes utilize multi-purpose acrylic adhesive on both sides of a conformable, foam core.”

Why don’t you buy one from ADM Accessories (admaccessories.com)? He makes them himself, are high quality, and I think he’s got lots of stock (if not, he can make more)

Hi Ron,

Thanks for the link to the Celestron plate on Amazon. Right now, the link leads to a Amazon page with the Celestron Universal Mounting plate but it mentions the plate is currently unavailable. Later, I will check out the Celestron store on Amazon and see if I can locate something similar that is in stock. 


Thanks,
Alex

Hi Dale,

Like Brian, I was wondering about how well the built focus controller works versus the Boss II unit. It appears to work fine, which is making me seriously consider this path to minimize clutter.

Thanks for all of the info!

Re: Manage Cables Which Plate to Use for Top Mount Hardware?

Hi Brian,

This is a impressive unit. I like the brackets for a Losmandy plate and the software interface, plus it can control my starlight focuser. My only issue is I already have some hardware I plan on using in my system like a USB hub, starlight boss II, rigrunner, etc. If I had seen this first, I might have gone for it. I might still, if I run into problems.

Thanks again,
Alex

Re: Important Update from the ASCOM Initiative #APCC #ASCOM_V2_Driver

 

It really depends on your setup. If what you have works, there is very little compelling reason to change. Here is the change list from the release notes that users can be concerned with, from the release notes. Personally, I would update because I know what a pain it is to support software when everyone uses outdated versions. For users, there have been some quality of life improvements and some very minor updates to precession precision. Since there is a clean revision to the 6.4 platform, I don’t think there is any significant harm.

Changes for Everyone

  • Device Hub
    • Side Of Pier and Destination Side Of Pier will now be calculated by Device Hub if not available from the downstream driver.
    • The dome shutter can now be opened and closed when slaved.
    • Exceptions are now trapped and logged during dome slaving calculations.
  • All references to the Yahoo ASCOM Talk forum have been replaced with references to the new Groups.IO forum.
  • All links referencing the ascom-standards.org web site now use HTTPS instead of HTTP.
  • DeltaT predictions, good to December 2021, have been revised based on the latest IERS predictions.
  • The SOFA component has been updated to use the latest IAU 21st July 2020 - Version 16 SOFA release.
  • Chooser Properties Button - detailed failure information will now be provided if a driver does not connect correctly.

Platform Issues fixed

  • A serious bug was introduced in the Astrometry.Transform class during Platform 6.5 implementation, which prevented a single instance from being used for multiple transforms. The bug has been fixed and Transform now works as it did in Platform 6.4.
  • Clients will now see the correct type of NotImplementedException (PropertNotImplementedExceptiony or MethodNotImplementedException) when Alpaca devices report that a member is not implemented.
  • Diagnostics:
    • Now correctly reports the Windows 10 operating system version.
    • A rare exception that occurred when recursing registry keys has been fixed.
  • Corrected a typo on in the message given if a disconnect fails when using the Choose and Connect to Device form. Thanks Marco!
  • Platform installer:
    • Works properly on machines whose PC Name contains a space character.
    • Handles unregistering drivers more gracefully.
    • Checks that the Windows Task Scheduler is enabled before attempting to create the earth rotation data update scheduled task.
    • Sets the required registry Profile store ACL on every install rather than assuming that it is correctly set when upgrading from a previous Platform version. Access to the Profile store is confirmed after setting the ACL and any issues will be reported by the installer.
    • Now detects whether controlled folder access is enabled on the user's Documents folder and aborts installation in this scenario.
    • Removes simulator COM entries when uninstalled.
    • Provides clean reversion back to Platform 6.4.
  • Device Hub
    • Improved support for locales that use comma as the decimal separator.
    • Profile settings will now be preserved when upgrading.
    • SideofPier exceptions will now be forwarded to the client.
    • SlewDomeToAzimuth now responds with the correct exception if an invalid azimuth value is requested.
    • The telescope Slewing flag is now correctly maintained when the mount is pulse guiding.

Basically, update if any of this sounds important.

Important Update from the ASCOM Initiative #APCC #ASCOM_V2_Driver

 

Good news, everyone! 

There is a new update from the ASCOM Initiative! Looks like the latest version fixes some of the bugs introduced with 6.5 that affect plate solving in APCC. Here are the details, straight from the source. 

Hi all,

We have just posted a release candidate for ASCOM Platform 6.5 Service Pack 1: https://github.com/ASCOMInitiative/ASCOMPlatform/releases. This addresses a serious bug in the Transform component that was introduced in the initial Platform 6.5 release and which is known to have manifested in the Astro-Physics driver and in the AstroTortilla application. Other drivers and applications may also have been impacted.

If you have installed the initial Platform 6.5 release, we strongly advise you to update to the service pack 1 release candidate.

If you have already installed an early beta version of the service pack 1 release, we also advise you to update to the release candidate because it includes further fixes and supports clean reversion to Platform 6.4 SP1 if required.

In addition to fixing the Transform bug, service pack 1 includes several Device Hub and installer fixes. The Platform releases link above contains a full list of changes.

The Platform and Developer Components installers have been submitted to VirusTotal and are passed by all major anti-virus scanners. SHA1 and SHA256 checksums are listed immediately above the installer executables in the releases link above.

Best wishes, Peter

Yep, I did the switch. The FocusBoss controller, as nice as it is, is no longer used. The UPBv2 drives the HSM35 motor now using a cable I made based on the pinouts provided by Pegasus. It works like a champ. I did not use the thermal compensation feature of the FocsusBoss controller and its ASCOM driver. If you do, you would have to give that up to use the UPBv2 to drive the motor. Since I have NINA trigger an automatic autofocus operation if the HFR has trended more than 10% from the previous AF operation, I never had a use for the temperature compensation feature of the FocusBoss anyway.

When I decided to go for the UPBv2, the one thing I was ultra hesitant about was using its built-in stepper motor controller to drive the Starlight/Optec HSM35 motor instead of the rather substantial FocusBoss controller, and I also just really like the Optec ASCOM driver for their focusers and moving things to the UPBv2 would mean not using those anymore. All the other changes - going from a 8x  powerpole hub to the 4x coaxial power connectors, a fantastic Starlink USB3 hub to the one built into the UPBv2 when I have a QHY600 spewing 120MB frames over the wire... those things worked and adapting my powerpole cables would be simple. But it was that focuser controller that I was wary about.

The focuser controller on the UPBv2 can drive any number of stepper-based systems and the setup of it in the app has presets for some popular ones, including the HSM and PosiDrive series from Starlight/Optec. The only thing is that you need a cable to convert from the UPBv2's pinouts in its 8-pin modular jack (aka RJ45) to the pinouts of the RJ45 connector on the HSM motor. You can buy a ready-made cable from Pegasus, or make your own with the pinout diagrams provided by Pegasus. Since I wired my house with cat6 ethernet a few years ago and I still have an ungodly amount of cable left over from that project, I opted to make my own and it works fine and the Pegsus ASCOM driver for focusers implements what I need, so I'm not missing the Optec one either.

When I set up now, I just slide the 130GTX into the DOVEV10 on my Mach1, connect single USB and power cables to the UPBv2, remote desktop in to my mount-side miniPC and turn on the auto-dew feature of the UPBv2. It will monitor the dewpoint and start ramping up the heater straps as ambient temperature and dewpoint converge. When it's dark enough I tweak my polar alignment in SharpCap and get on with my imaging once it turns astro-dark. Breakdown in the morning is just as simple.

All in all, I'm very happy with it. I subsequently bought a Pocket Powerbox Advanced from Pegasus, which is basically a mini version of the UPBv2, to go on my airline-portable setup (CFF 92 f/6, RST-135 mount) so that I can elide the separate USB and powerpole hubs from that rig and add a dewpoint-controlled dew heater in the same motion.
