ABSTRACT: Vacuum magnification of an image with fluorescent sc7een does not have
high resolving power. The author uses con'L-act electro-Loptical ;onverters with a
resolving power of 0.05 mm and a working range of 10 mm, findiA,, this system to be
very efficient for spectroscopy. He has also used these image iiagnifiers in
combination with interference monochromators. For the region t-f Hc;.< the gain
in exposure is a hundredfold, and, hence, such monochromators sLould be used for
cutting down on cloud background when observing emission ne~ulati. The author has
ed an interference filter for the H,,< line with 4d, f(r which the Fabry-

ABSTRACT, The diffuse nebulae NGC 7000, NGC 6618, NGC 6523, NGC 19761
NGC 7822: and IC 1318a have been measured by means C"If an interfero-
meter equipped with a filter for the 11, line. Radial velocities were de-
termined in all nebulae. The northern part of the nebula NGC 7000
is an emitting source of uniform brightness; its emission is of -ther'_~
mal nature and may be considered as due to thermal motion of the H III
zone. The diffuse nebula NGC 6618 consists of filaments which are
ibelieved to be the result nf the explosion of a supergiant star. Them,

iVelocities of various parts of the nebula in radial directions were
~found to range from -40 to +61 km sec-1. The velocity of the cen -tral
.part was found to be +27 km/sec-1. Measurements in the central, bripht
ipart of the nebula NGC 6523 yielded positive and negative velocities.
This nebula is considered to be a dilat;ng gaseous formation with
an expansion velocity of 25 km see-'. The proper mqtion of the nebula

ABSTRACT: A description and some preliminary results of the expedition of the scien-
tific research vessel IlVityaz ",,-carrying a party of 24 Soviet astronomers to Manuae
t 11
Atoll to observe The otal solar eclipse,,,,of 30 May 1965 are given. Oceanographic
investigations were also conducted at pdfnts along the cruise route - Vladivostok,
Samoa, Manuae Atoll, the Hawaiian Islands, and Vladivostok. The Soviet expedition
had at its disposal two high-quality spectro raphs, several interference instru-
ments, and radio telescopes. At the time (9926m34s) of totality, cloud conditions
hindered visual observations. However, the interference instruments yielded valuable
negatives, and direct long focal length and color photos were obtained. Some spectrc
grams of medium dispersion were obtained, but the high-dispersion spectrographs
needed for the entire 220 seconds of totality were unsuccessful. Measurements of an
interference rhcto of the solar corona obtained in the red line of FeX at a wave;- .-i;
