Markarian galaxies

Prisms in this had a low dispersion of 180 nm/mm in order not to spread out the galactic core spectrum too much and confuse it with other objects.

[8][9] The FBS continued observations till 1978 with a full spectra survey at high galactic latitudes.

[4][10][11][12][13][14][15][16][17][18][19][20][21] A list titled "First Byurakan Survey" circulated in 1986, including the original 1500 galaxies and 32 extras numbered from 9001 to 9032.

[4][23] In 2005, the "Second Byurakan Survey" (SBS, SBSSS, BSS, MrkII, Markarian II) was carried out, extending the MrkI survey to fainter objects, making a catalogue of 3563 objects of 1863 galaxies (SBSG) and 1700 stars (SBSS); 761 of the galaxies are AGN (155 Seyferts, 596 quasars, 10 blazars).

[4] A custom designator for the galaxy core of "s" for star-like or "d" for diffuse was used, with hybrids of "ds" or "sd".

[27] Some objects are actually giant glowing regions of ionized hydrogen in a galaxy including Mrk 59, 71, 86b, 94, 256b, 404, 489b, 1039, 1236, 1315, and 1379a.
