Park 4 vs Park 5 #Keypad

Christopher M <mirfak@...>
Hello Everyone. Thank you for the responses.
I have a Mach 1 but I assume this applies to any of the mounts other than maybe the Mach 2 who's encoders are not imacted by loosening the clutches and moving the mount manually. I run a portable setup, not a permanent one, so mount will never be in eactly the same place each time, meaning the levelness of the mount base and tripod will vary from setup to setup even with the built in bubble level on the base of the mount. That means I consider every new setup to be inaccurate until I finish proper polar alignment and star syncing. On a side, note, a RAPAS is on my wish list. Currently I'm using a Polemaster as I had one. Cheers! Christopher |

Hi Christopher
For leveling purposes does your 1100 mount have a bubble level in the mount base ? This should be sufficient to allow you to get leveled during set up because your RAPAS polar alignment should allow for slight errors in level. I would suggest having your mount in Park 2 when you set it up and take it down and don't mess with the clutches (I assume this is what you referred to as "lock knobs"). The problem with loosening the clutches is that you risk losing the pointing accuracy of the mount. Mike |

You can use either one.

Is Park 4 as accurate a starting point as Park 5? I assume it is. I ask because keypad software 4.19 (4.19.3 for me) does not have a Park 5 position. Park 4 looks effectively the same to me as Park 5 except that the OTA is pointing the other way. Note that I'm a portable observer and imager and I use the lock knobs all the time to move things around before I get it all going. ie I mount my OTA in roughly a Park 2 position then swing it around and level it in usually Park 1 or Park 4 and start up the mount from there. Thanks in advance. Christopher -- Roland Christen Astro-Physics |

I use both Park 4 and Park 5 to level the telescope and compare them. The difference is that for one of these park positions, I have the knobs for the saddle dovetail up while for the other park position the knobs are down and easy to set a bullet level on the saddle.

Sorry, I goofed. You are correct, Park 1 has the OTA horizontal pointing north. Sorry.So does park 5. Just the ota is on the east side instead of the west. To anyone reading: Here are the positions all explained: https://astro-physics.info/tech_support/mounts/park-positions-defined.pdf |

wrong, the same as park 1!!! Both 1 and 5 have the telescope looking north! Konstantin Von meinem iPhone gesendet Am 30.01.2023 um 00:00 schrieb Mike Dodd <mike@...>: |

Park 5 is the same as Park 3, but the OTA is on the opposite side of the pier. I used Park 3 many times. The only reason not to use Park 3 is that as soon as you unpark, the mount moves into a counterweight-up position, which (as I understand it) can create problems with some software. Park 4 looks effectively the same to me as Park 5 except that the OTAYes. [...] I mount my OTA in roughly a Park 2 position then swing itUse Park 4 instead of Park 5. --- Mike |
