Ugh so it ended up way longer than I'd planned and I only did part 1 since I've been working nights and unable to get the scope out.  C&C are welcome and I might revise it regardless just because I realized after I was done that I recorded it with less than 100% screen opacity.  I'm trying to keep this just a basic guide to get folks going with guiding so keep that in mind.

 

Part 1 covers basic settings only.  Hopefully I'll have clear skies tomorrow night so I can do a 2nd installment covering calibration, drift alignment, and how to interpret the graph.  Looks like a monsoon is coming right now so I'm not feeling overly optimistic.

I was excited to watch it, but had the same experience as John, actually I was typing this when John's post appeared.

The link works now.  The video is good.  Not a lot of breaks, subject changes or stuttering and "um's"

 

The only issue I had with it is that the video is very dark.  It was almost like the screen brightness was turned way down and the screen capture picked up on it.

 

Thanks for the link.  I look forward to seeing the next installment.

Yeah I think that was the opacity thing I mentioned. Probably end up redoing it just for that reason. But look at the bright (ha) side: you can watch it at a dark sky sight without going blind!

Thanks so much for posting these! My program looks a little different as my version is 2.5.0 dev5 but it's mostly the same. I did see one setting on mine that I might have missed you mentioning and that was the check box for "Use Dec compensation." Do I need to check that? I also have a box that says "Use backlash comp" and was curious about it. I do have some pretty nasty backlash on my Dec axis when the motors switch directions but hopefully I can PA well enough to avoid making too many Dec corrections. Again thanks for these videos!

Thanks for posting your video, I hadn't realized before how important changing the aggressiveness for RA and Dec could be to the quality of guiding!

Hmm I thought I had the latest version so I guess I'll have to download and play with the new features. Not sure what dec compensation is without reading the manual.

As for dec backlash it's really not an issue with a slightly out of balance dec, a level mount, and the right settings. If those are good then your dec drift will ALWAYS be in one direction only. As you saw my backlash is horrendous as I never tuned it after taking my mount apart. I probably should but since it causes me no issues with guiding I just haven't bothered. I usually end up changing the dec guide mode from auto to north or south depending on which direction my corrections are going. It's not necessary really but it can avoid a dec correction switch.

You may have the newest version. I downloaded mine at a link on their page I believe that related to my guide camera the ASI 120 if I remember right. I may be wrong on that.

Also it is important to enter the degree of declination of the star you are following if I remember correctly? I am fixing to finish up the first video and move to the second one. I have no ASCOM connection and instead using ST4. I will be using the polar alignment tool on PHD2. I understand it is a little more trial and error to do it without ASCOM since my scope has no way of knowing what it is pointed at, but according to their instructions I can still use the tool. Thanks again!

Yeah you'll want to enter the declination manually.

I like the explanation of drift alignment, didn't like the explanation about star tolerance leave at 0.50 since 1.00  will remove the annoying alarm when the guiding star faints. The rest was very cool! keep them comming! :waytogo:

 

A video worths a billions words!

Those were helpful I changed some of the settings in my PHD2 I look forward to trying it out in the field.

I found your videos to be a real step up from the normal videos and as I've only been out a few times with default settings left, your videos will help me get to the next level. Big thank you for taking the time to help - just need some clear skies to try it all out. Haven't been out for a month!
