It's interesting because their separation is an indication of the actual angular measurement of the dimmer Airy discs. If they are separated by at least Dawes, the Airy discs cannot be physically smaller without having a huge black or dark space between them. And I suspect the ring structure would also shrink, if you can see it, would appear more like a classic figure 8 than an elongation. Of course there are obstruction and seeing effects, so a larger sample is needed. These are the first three on the Auriga list.
CatalogNumber=STT 112 (P.A. 50 SEP 0.9 MAG 7.92-8.21)
Comment=Tiny but beautiful easy split equal pair at 320x. Companion held NE. Well defined dark space. Both amber with faint ring. Seeing 9/10 NELM 4.
CatalogNumber=STF 799 (P.A. 162 SEP 0.8 MAG 7.3-8.26)
Comment=Fainter companion easily seen SSW at 320x. Dark space evident most times. Faint ring mostly around primary. Seeing 8/10. NELM 4.
CatalogNumber=HU 1233 (P.A. 28 SEP 0.7 MAG 9.44-9.67)
Comment=Very difficult. Elongation seen generally NS at 320x. Fainter companion suspected N. Dark space glimpsed once, maybe seeing effect. Seeing 8/10 NELM 4.
