HI J, Sure lay 'em on me! I do not think anyone memorizes a Lunar form! I also have my own multi-body form. There are infinite combinations of forms but the bottom line is for the forms to contain the same info. Thanks much. Mike Burkes My rote memory "forms," for both 229 and 249, have one duplication copying only Ho from the Hs-Ho line to below the Hc line to get intercept. I suppose I could forgo this duplication, but it would be a bit more mentally taxing to look at numbers from either different columns or far down the same column (I often do one or the other). Otherwise I do no other duplications. I tend not to use pre-made forms as I find them limiting for different kinds of sights. I pretty much run along for what I need to do and adapt as necessary. For example, for a sunline verses an ex-meridian, I need to calculate LHA (or t) for both and use the same basic "form" but I don't pre-print anything to accomplish this task, as it varies from there. I just "download" it from my head for each kind of sight. The only "form" I use these days is a Bruce Starke Lunar as I am too much a newbie with them to memorize the form yet. If you'd like, i can try and photograph or scan one of my nav notebook pages to show you how I do it. Jeremy ________________________________ Gas prices getting you down?
