Hi,
I have a Casio fx-115MS which is quite nice for celestial calculations:
Pros:
+ You can enter formulas and use memories (similar to the TI).
+ 9 memory places, which is enough for lunars
+ Can enter angles as ddd mmm.mmmm or as ddd mmmm ssss.sss
+ Solar powered
+ Quite inexpensive (about 25 euros in Finland, probably even less expensive in other parts of the world.)
Cons:
- Formulas are lost when turned off! (but on the other hand that helps in forcing one to memorize them ;-)
- Can display results only as ddd.dddd or ddd mmm sss.sss (but not as ddd mmm.mmmm). But I haven't found that to be too much of a problem when one is aware of it: write down intermediate results as ddd mmm ssss, and convert to dd mm.mmm for the final values.
Cheers,
Harri
