Based on S&W 2/2001 by Wolfgang Steinicke. See also WWW.NGCIC.ORG

NGC2163 is also CED62

remove CED62 entry

add to NGC2163 PA=0

add to NGC2163 size 2x3 minutes.

add to ngc2163 magnitude 14

add to NGC2163 from CED62 decribtion Two_symmetrical_fans_extending_N-S

(For info NGC2163 position 6 07 49.62 +18 38 42.2 )

(NGC2163 is GSC 1317.311 or DG87 or LBN855 or GN 06.04 or LkH alpha 208)

(wrong in Millenium atlas but correct in new Uranometria, Deepsky field guide)

4) 2001-12-28

LMC Large magellanic cloud. Size 420x300. Best fit for amateurs based on photos and maps. Orientation PA=120 degrees for main bright part (the original 170 degrees for the H2 gas cloud is not very practical !)

5) 2002-5-26

M40, Winnecke 4   Position should be    12:22 18,   58d05 00,  Size 1.5 arc min

NGC1841    Position should be   04 45 23.1 ,    -83 59 49

NGC4893A  Position should be 12 59 59.9  ,   +37 11 12

PK64+15.1  (in ACE the real value is wrong but position is correct in SAC 7.2 (RA 18 50 02,  DEC 35 14.6)

NGC2736  Position should be   09 00 17.0  ,    -45 56 53

6)  Correction for  "Wild's Triplet" => second name   Arp 248  Position 11 46 42  -03 50 10

Corrected position for M24   18:16 54.0    -18d 39 00   (Is not IC4715) Size 120 x 45  PA=45 (position and PA based  on Realsky measurements)

9) 2003-1-10

Remove chi  and H persei names of double cluster NGC 884  & NGC 869. See article page 116 S&T feb. 2003

10) 2003-3-1

NGC 7023, better position 21 01.6,  68d09.8   Size 8 min.

11) 2003-3-10

keep NGC3544/NGC3571 , remove NGC3571/NGC3544 remove

NGC4776/NGC4759-1 delete but use describtion GX/[SO]/F/S/R/vlbM/p_of_Dneb for NGC4759A/NGC4776
