Just wondering as I prepping to mount my 1100GTO. I have removed the old CGE-Pro from the pier and getting ready to mount the 119FSA adapter and wondered if everyone used all 8 1/4-20 bolt positions

Hi Mike, If anyone still has the original CP4 released WHITE case – consider drilling the two bottom corner holes, as Tony (a.k.a. Harley-Davidson) shows in his CP4 video. My original,

Sounds like it is more measuring the accuracy of the mount and closed loop slew than the plate solving. I would think you want to take a FITS image and plate solve with ASTAP and compare the

189 points. Can I do dec-arc modeling with the current APPM version? Is it as simple as making a model with just a bunch of points on my target's declination? Or do I need to wait for the next CP4

Here is my proposed experiment to measure accuracy of different plate solvers. 1. Choose a star (A) mag ~9, plate solve, re-sync, and then slew back to it. (in SkyX they call this closed loop plate

Hi Joe, In addition to Mike’s comments regarding bugs, I would add that some folks use their astro equipment in desert-like settings where dew is not a significant problem, but dust is. Hence

How many sky data points? 10-minute exposures at 0.88 arc-sec/pixel may be a challenge without Dec-Arc modeling. -Ray

George runs a Shuttle fanless in his observatory. AP has one in our observatory, and there is another one in our office. All 3 have been absolutely flawless. I haven't looked at the newer versions.

Don, It should be adequate. A friend of mine used a single 1000 Newton DL2 for his observatory and he had a Meade 14 on a Celestron CGX mount. It worked well. I opted for a dual column and I

My mount is an AP1600GTO-CP4 with Absolute Encoders. The scope is an AP130GTX. The camera is a QSI690-wsg8 at 0.88 arc seconds per pixel. I'm doing 10 minute exposures. On the next full, clear

Hi Wade, Remind me, which scope, image scale, and exposure duration are you using? If you are going to do a validate, you would want to do a "Model 5x and Park", which is an option in APPM. This

One more update: tl;dr: Inconclusive. The last couple of nights has been tough. We had a weather change and Wednesday night was a loss. Early evening was clouded over, so when NINA started the

Hi Don, USNO B1.0 is over 80 GBytes, consuming too much bandwidth to download from the USNO website. Unfortunately, that leaves A2.0 as the outdated alternative, so UCAC4 is the better choice now.

To Joe: I believe I read or saw somewhere (Maybe Tony's video) that plugging the holes will keep bugs out. This would only be a factor for those who leave their mount set up in a permanent

Thanks Mike, I'd be curious if your model number has a D in it, as I think there's maybe a confusion in model numbers between Mouser and Digi-Key? Howard's link from yesterday was for "RM15TR-C(71)"

Question to the group. Can anyone think of a logical reason to plug “drainage holes” with those rubber cones? Do we really want to make sure that any dew or other source of moisture

Hi again Ken I just received a shipment notice from Mouser for the RM15TR-C(71) caps. I was worried that they might substitute the same one that they recommended for you, but they are sending the ones

Thanks, Rolando. Should I vacation near a Black Hole, I will “heed your advice”. Bob ⭐️👽😳

What is the best way to test the accuracy level?

Hi Pete Those cone shaped plugs are used to plug the drain / vent holes in the bottom of the GTOCP4 housing. Tony (a.k.a. Harley Davidson) made an excellent video a couple years ago about the need to
