Observations of 500 Nebula.

M.90: C part strongly condens and nr circular, diam ! / 2 ' a , / s '; extreme parts of neby 

 eF and not distinctly seen, although sky v perfect. E at least 6' a, 7' sp to nf 

 in estimated pos = 20° ; greatest breadth at N not exceeding 1'. The C * looks 

 like a real N : neb in its totality not to be estimated Fr than of the 3 a order. 



GC.3124 not looked for. 



hl361 E np to sf in estimated pos = 135°; neby quite, certainly 3' Ig and '/ 3 ' br at 

 N ; N is G and E in the axis of the neby, its r evident. 



hl368 vB N distinctly resolved. 



hl378 pretty certain indications of C r ; S J of *... sf. 



hl383 Sr but not considerably Fr than the p neb ; N has evident traces of r ; *all m np. 



Iil384: diam '/,'; am the brightest neb of the 4"' order; r suspected but not ascer- 

 tained; *a 10 m ll f in the par. 



hl386; h!4Q2; hl405; U1408. 



Til386 much of the same character as hl308, but r more conspicuous: sev distinct 

 stell points both in the N and around it. Is the nf * 11™ nebs'? 



Iil402 conspicuously biN, or a dneb np and sf; components however probably nr in 

 the same par, as, at the measure in decl, the micrometer-wire seems to occult 

 both at once. Sky not sufficiently favourable. Place that of the seemingly brigh- 

 test point and obs agreeing well; *a 10™ np. 



Rem. h describes neb as "F , R" ; and it would consequently seem the more 

 diffic to identify it with the neb here obs, which is B and evidently E, as h says 

 nothing even of the duplicity, which nevertheless was very conspicuous and easily 

 visible, although the atmospheric circumstances not v favourable. The duplicity 

 is also remarked by R: "dneb ; F neby connects them". On the other hand, as 

 no other neb could be found nr, it is quite certain, that the object obs by me 

 must be identical with h!402. This neb corresponds consequently to the 2: GC.3171 

 and GC.3172. It is remarkable, that D'A 3 times of 5 has seen the neb Rd and 

 even "circularis", and that the duplicity should have escaped his practised eye. 



Iil405 according to my observation am the brightest neb CI. II, and should conse- 

 quently be an easy object for the Mannheim-Refractov — yet it was hardly seen 

 by Sf? Many *... twinkling through the neby, and r evident; C condens uncertain. 



hl408 follows 11405 s and so nr, that the neby of the 2 objects runs together ; ]> 1408, 

 much of the same character as 7/ 1368 and hl386, is yet much Br; N6 and resolved. 



h 13.99 bet 2 *... 12™ sf, ll m np ; diam no doubt Gr than 2'; N G and evidently r. 



h!404 seen once in v unfavourable circumstances ; E np to sf in estimated pos ab = 

 45°; perhaps 2 lg, at N '/,' br; M vB ; N no doubt r in Sr *... ; 2 *... np H'"12 

 and 10 m ll.
