The objects are then visible as planetary nebulae, exposing their long history of spewing material into the ISM, and further processing the ejecta. There are even reports that the central stars of some PNe may be engaging in nucleosynthesis for purposes of self-enrichment, which can be traced b...
This is a nice little event that happens fairly often because the constellation Cancer is near the ecliptic. I like using my 15x70 binoculars with its 4.5 degree FOV to frame the cluster with the Northern and Southern Donkeys (Asellus Borealis and Asellus Australis). The Beehive is visible fro...
bring on the step between these two nebulosities which is at present wanting, and would lead us to surmise that this nebula is a stupendous stratum of immensely distant fixed stars, some of whose branches come near enough to us to be visible as a resolvable nebulosity, while the rest runs ...

I first pan the bino as described above, from Alpha TRI to M33. The galaxy is now clearly visible in the FOV of the bino, filling the whole E side of an equilateral triangle defined by three 8mstars (H9483, HD9269, TYC2293-912-1). It shows up as a faint, diffuse grey haze, elo...
The reason why Messier marathons take place from mid March to early April is because this is when all of the objects are visible in one evening. Other times of the year aren’t suitable as some of the objects will be in daylight or below the horizon etc. ...
After having much difficult locating some M/objects with my 15/70 binoculars, I cheated tonight and ran most of the last stretch with my 80mm Master Birder using a Vixen 8-24mm zoom and Teleview correct image diagonal, mounted on my Celestron SE Goto mount. Power range from about 18X to ...
