You might also post a picture of the AF curve you are getting. Definitely do your experiment with Bahtinov mask and have NINA measure all of the image HFR values. Goal here is to see whether there is

OK so I measured 1000 steps = ~4mm (no calipers but I have a set on order since I need them only) = 4/1000 mm per step = 4um/step My scope is an AT60ED so f/6 = 6 x 6 x 2.2 = 79.2um Width of zone =

Thank you Edward, this is amazing info! Yes, the ZWO has some backlash and I am hoping the NINA "Overshoot" method will minimize this I am going to do the calculations you present above and see what I

Recommending settings as absolute numbers is meaningless. I still suggest you start by?computing: (1) how many microns your focuser moves per stepper motor step. You can command the focuser to move a

I am using 1.10 HF3 - I have had enough to worry about so far without being on nightlies :) I also use overshoot with 300 as the backlash, which seems to work - I dont get flat curves, just ... not

Yeah I may turn off the trend part - I read that over on Cloudy nights this morning My scope is small so I am actually not flipping -- if there were no cables I dont think it would ever hit the tripod

For me Trends and Hyperbolic caused issues.? I use Hyperbolic. Which Plate Solver are you using?? ?What are your Losmandy and NINA meridian flip settings? ------------------------ Jim W Phoenix,

I have the ZWO focuser and thinking my step size is too big (although the NINA folks told me to increase it even higher than I have now) Initial step size: 4, Step size: 25, Exposure 10 secs, Method:

That’s great news. What autofocuser hardware? I put together a DIY system called “myFocuserPro2”. The documentation has good explanations of critical focus zone and backlash that helped me tune

Great news Nick.? What release of NINA are you using and which plate solver? ------------------------ Jim W Phoenix, AZ. USA Losmandy GM811G, NINA 1.11, ASI2600MC Pro, Sky-Watcher Scopes

Hi all, Good discussion on balancing. To recap: 1. Slew or position your counterweight rod to be horizontal. 2. At that position, there is zero weight on the DEC clutch pad, so carefully release the

Only with your amazing help! Found a Bahtinov mask in the basement so I am going to check out this focus I have a few trips to Bortle4 coming up in July/August that I really want to take advantage of

Nice work Nick. you've done a great job with this wrote:

Just wanted to say a huge thanks to everyone that offered help & suggestions over the last couple of weeks. I am really dialed in now. Had a great session last night, all automated with NINA (focus,

Question.. Doesn't the Wavy Washer require a machined groove that not all mounts have?? Not positive, but I don't believe my mount will accept one.. Derek _____ Sent: Friday, July 02, 2021 11:04 PM
