Regalo de Estrella 6" f/5.4 @ 59x
Easy to find off of γSge, 2° or outer telrad circle from the star, bright, large, the dumbbell shape is quite clear, a fainter outer halo forms a more circular shape around the north-south aligned inner region, no color noted, no central star

45cm f/12.8 Herschelian speculum
My sister discovered this nebula this evening in sweeping for comets; on comparing its place with Messier's nebulae we find it is his 27. It is very curious with a compound piece; the shape of it though oval as M. calls it, is rather divided in two; it is situated among a number of small stars, but with this compound piece no star is visible in it. I can only make it bear 278. It vanishes with higher powers on account of its feeble light. With 278 the division between the two patches is stronger, because the intermediate faint light vanishes more.

Nebula without star, discovered in Vulpecula, between the two forepaws, & very near the star 14 of that constellation, of 5th magnitude according to Flamsteed; one can see it well with an ordinary telescope of 3.5-foot; it appears of oval shape, & it contains no star. M. Messier has reported its position on the chart of the Comet of 1779, which was engraved for the volume of the Academy of the same year. Observed again January 31, 1781. (diam. 4') "

The 'Dumb Bell' Nebula, just visible with a 1¼-in, finder. In a rich field we find two oval hazy masses in contact, of which p seems to me the brighter, as it did to H. His reflector failed to resolve it, but showed the dark notches (which, as Darby remarks, are usually represented two deep) filled and made protuberant by faint luminosity, converting the whole figure into an ellipse. The Earl of Rosse's 3-ft. speculum was though to reach its starry components: his 6-ft. surrounds it with an external ring having a neck like a retort. Bond's achr. also seemed to resolve it, but there, as in D'A.'s figure, the form shown in small instruments is lost. The minute stars in it, of which I have picked out two or three with 5½-in. achr, and 8-in silvered glass, and Denning sees 7 with 10-in. spec., are admirable test for superior telescopes. Ingall has claimed 18 with 5½ dialyte, from keenness or vision, and Se. has drawn many more. They seem, however, to be merely part of the host of the Galaxy; for Huggins finds there, by simultaneous comparison, nothing but luminous gas. A star in the centre, 13 mg., but on photos 11.7 mg., is probably the nucleus.
