Corrections to OITHv4

Glad you made it here!

Thanks to Jim Kaminski and dogged perseverence, a number of mistakes have been found that will be included in the next version. This page is for you to transcribe into your current copy. Some fixes are relatively minor but others could cause frustration if, for example, an object is not where the books says it's supposed to be.

If you find a detail in need of repair, please let me know. Thanks!

In the next version – and you're the first to know – every RA/Dec address will be updated to 12.2010 locations. Voyager 4.5.4, a wonderful program, is being used for these new addresses. Again, most of these changes are relatively minor, but in the name of completeness... The new version will likely be ready by December, 2010.

So without further ado, here are the (partial) updates to OITHv4... more to come:

Page 20
- n1023 should be labeled as LG

Page 21
- n2903 and 2905 are the same object; delete 2905 (see LEO)
- n4125 should be labeled as EG
- n4594 is out of numerical order

Page 23
- IC1795 should be deleted; same object as n896
- PK215+11.1 should be deleted as it's mag 15.4

Page 24
- You can add Gamma AND to the list of Albireo-type doubles

Page 25
- The Sculptor Galaxy will be changed to the Silver Dollar Galaxy

Page 26
- Jupiter's moons now number 63; and you may as well remove the asterisk because there's no reference to it

Page 27
- The parent comet for the Leonids is 55P/Tempel-Tuttle

Page 28
- M44 in CNC is currently labeled M41 (how'd that happen?)
- CVN is not labeled - it's south of (below) the handle in UMA

Page 33
- Remove IC1369 CYG from the mag 7 list, it's too dim for this list

Page 34
- Remove PK215 from the map (see Page 23 note)

Page 35
- Remove PK215 from the list

Page 38
- There should be a space in the RA/Dec address, after the #9

- CNC: Remove "Triple" from Iota CNC; it's only a double

Page 48
- CMA: Sirius has a separation of 3.7" (if you can split 'em)
- CMA: n2359 needs an OIII filter for best contrast
- CMI: Remove PK215+11.1 as it's too dim at mag 15.4

Page 49
- CMI: Remove PK215 from the map (unless you've got a huge mirror!)

Page 50

Page 53
- In the photo inset, n1027 is the cluster just to the left of IC1805
- Below the inset, the letters CEP are just peeking out

Page 55
- CEP: 7762 position not quite correct; should be about 3/8" up and left of its present position
- CEP: Mrk50 should be designated as 7635CAS

Page 56

Page 72
- HYA: ngc3109 should be classed IG, type SBm

- HYA: ngc 3109 should be about 1/4" higher and 1/8" to the left (NE)

Page 74
- LAC: * 8 is a 7-star system; delete "Quadruple"
- LAC: ngc 7243: insert "use low power" (it's true there are some variable stars, but that doesn't help finding the object)
- LAC: ngc7296 should be indicated as ngc7295/6 as it's one of many objects with 2 ngc numbers.
- LAC: IC1442: delete 7243 from the line (what was I thinking?)
- LEO: ngc 2903 and 2905 are the same object, should be just 2903
- LEO: ngc 3607: copy should read, "near 3905+08"

Page 76
- LEP: alpha * is a binocular double, probably adding just the words is OK

Page 78
- LYN: distance to ngc2683 should be a mere 160KLY (not 16MLY)
- LYR: the name of beta is Sheliak
- LYR: delta is part of Steph1
- LYR: M57's most current distance measurement is 2300LY
- LYR: M57 has another interesting factoid to add regarding size relationships, that the ring is as large as our Solar System out to Pluto

- MON: (add) ngc2282 RN Faint, some *s involved 3x3 06:47.5 +01º18 10

Page 88

Still a bit more to proofread and more to come... little at a time.
