I was in Cabo San Lucas on the beach where everyone broke down in tears at this my first eclipse. Looking forward to 2024.

Best wishes, Michael

Re: APCC Pro appears to have crashed and all settings reverted back to factory settings #APCC

Chris,

I sure hope its not going to happen again. What was particularly troubling is that after APCC closed, my mount just
continued to track without protection of APCC limits. Thankfully the target I was imaging was pretty high so the
mount was just pointed near the top of the wall of my obsy, but I could have easily had a pier crash had I been
imaging to the east when this happened.
Are you sure about that? When APCC disconnects the mount will stop tracking after a short period of time. This feature is not in APCC but in the mount. That is, if the mount does not see any commands from APCC it will stop tracking in about a minute.
This was added into the mount's firmware exactly for cases such as APCC crashing, or the connection to the mount is lost.

-Ray

No, don’t go down the rabbit hole of thinking disk-backed virtual memory will save you from anything. It only delays such a problem’s eventual conclusion and is a waste of good drive space.

    _._

 

I expect my HOA is more picky than you wife (if not, well, my sympathies).  Put in the pavers with a really good foundation, then let the grass grow for a while.  They are not very visible, in fact from the side they are not visible at all except right after mowing.

 

 

Bigger pavers are probably better but it is more about how deeply you build a good foundation that is not affected by moisture. I don’t have to contend with freeze/thaw, I expect that might be difficult to reasonably counter.  But just moisture (which I have in abundance) is handled by a lot of gravel and sand (remember you can make the gravel/sand bed wider than the paver and grass covers it, if you haver it a few inches down).

 

In my case the holes accept the spikes and self center; I can set the whole thing up night to night and before I polar align I am usually within a few arc minutes just from repeatable placement (I do not remove the mount from the tripod, just the OTA, and weights, then move it on a handtruck). But cranking down a lift should work the same way.

How bad this gets for any one person depends on ther soil type and moisture and all that. I use pavers sunk into the ground but major shifts aren't really anything noticeable with my clay soils. I'll start the evening guiding around 0.3" and it'll get to about 0.4 or 0.5". I'll touch up the PA every night, though. It's usually off by around 5-10" over the course of a day or two. I PA using sharpcap through my main camera.

Last night I tried out my portable "wheely bar" setup for my FSQ106 and AP600 GTO mount. I used 1 foot by 1 foot, 2 inch thick concrete blocks under the leveling screws and did a polar alignment with the polar scope in the AP600.
My first image, 30 minutes O3 on NGC7000 was amazing. The tracking, was 0.25" with pretty well no corrections at all. Granted the seeing was really special last night, very rare.
My imaging uses Voyager and I typically focus each 30 minutes where the scope does a goto to a nearby star in the Voyager database and then continues imaging.
After the first image I started to get large gradual swings in the dec and RA, up to 4" of arc errors after which Voyager would abort and start over. After two or so tries I then managed to get another nice sub. Likewise for the third sub. After this, I was no longer really successful.
So I took a look at the polar alignment through the polar scope and polaris had moved quite a lot. Probably a good 1/8 to 1/4 of the field of view.
So my thinking is that as the night progressed, and the scope changed position, the blocks started to shift. This happened during the exposures.
So, how do you image on grass? Is 30 minute subs out of the question? Do you polar align frequently?
Thanks for any insight.

Hi Tom I'm in Calgary and image on grass as well with my AP900GOTO and a Televue NP127is on an AP portable pier. I tried cement blocks as well but found they move too much as the weight of my rig compresses the grass under the blocks. I have since gone to  three steel plates with two 8" pieces of rebar rod welded to the bottom of each plate. I pound these into the ground and leave them there. As the grass dies under them, they sink down to the dirt and are reasonably, but not totally, stable. I minimize movement by setting up my rig several hours before imaging which gives the plates a chance to settle in a stable position. This works ok since I image at between 525 and 660mm f/l. This wouldn't be very satisfactory at longer f/l. My next thought is to set up a permanent pier to which I would install my rig every time I image or drill three 6" holes 4' deep and pour concrete pads level with the ground. 
Hope this helps.
Attached is a pic of my setup.
