Re: Mach 2 + 12.5" AGO iDK?

Well, I've never tried that scope, but I have loaded my Mach2 to the limit and imaged/guided just fine. Balance is critical and is easy to do. Weight makes for larger moment, which makes the mount

Re: GTOCP4 Caps

Hi Karen, Now I see ... in the KIT, those are actually all, in fact, desert “Dust Caps”, but I like to use them to keep any contaminants, wet or dry, off the pins. Makes sense now. I mistook

Mach 2 + 12.5" AGO iDK?

What say ye? 12.5″ Imaging Dall Kirkham | AG Optical 46lbs, but would need to add focuser (8lbs), TCS System (1lb), and camera/accessories (call these 5 lbs). The OTA is about 18" tall (maybe 17.5"

Re: 119FSA attachment

Hi Pete, I’m kind of new to the forum, so take my thoughts with a grain of sand. I’m building a pier to which I will attach the 119FSA for an 1100GTO I hope to have soon. I plan on using all 8

119FSA attachment

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

Re: GTOCP4 Caps

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,

Re: APPM model how many points portable?

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

Re: APPM model how many points portable?

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

Re: GTOCP4 Caps

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

Re: Interesting Behavior with APCC Pro and Pegasus Astro UPBv2

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

Re: Powering Remote Imaging Systems

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.

Re: AP1100 park position question

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

Re: Interesting Behavior with APCC Pro and Pegasus Astro UPBv2

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

Re: Interesting Behavior with APCC Pro and Pegasus Astro UPBv2

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

Re: More APPM Results -- Can Someone Help Me Understand This?

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.

Re: GTOCP4 Caps

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

Re: GTOCP4 Caps

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)"
