Houston calls this a "challenging planetary." He notes that "many catalogues and atlases mistakenly call this object IC 1298. It is about 1' in diameter, and, though it has been catalogued as faint as 14th magnitude, Tokuo Nakamato of California reports it to be easily located with his 14-inch reflector. He also describes the planetary as 'not faint, large, oval, and uniformly bright.' "
Steve Coe, observing with a 17.5" f/4.5 at 100X, notes: "Pretty faint, pretty small, fan-shaped nebula with 2 stars involved at 135X. UHC filter works well with this object, it is somewhat difficult without the filter. Looks somewhat like Hubble's Variable Nebula. This object has been mis-labelled IC 1298 in a variety of sources.
Observer: Yann POTHIER (France) Your skill: advanced (many years) Object: IC 1295 (PK 025-04.2; PN G025.4-04.7; ARO 8) Category: planetary nebula Constellation: SCT Object data: Vmag=13.5; Bmag=15.0; 90"x80" (107"x87" for IDB); type IV; central star of Bmag=15.0; discovered by Safford before 1888 (as a PN by Curtis in 1919).

Description: at 87x, small nebulous area (large for a PN), faint even with UHC filter, near NGC 6712 (dist 27'); mag11 star against the W border, better seen through OIII filter, faint stars around; at 100x, faint PN, medium sized (UHC); at 145x + UHC, faint and diffuse, with quite sharp edges; without UHC, very faint, without defined limits.

Instrument:12-inch Dobsonian Reflector Telescope.
Deep Sky Filters:Ultra High Contrast.
Sky Conditions:The fainter parts of the Milky Way are barely visible.
Transparency of the Sky:Haziness only visible on the horizon.
Seeing:Atmosphere stable with little interference.
Object Type:Planetary Nebula.
First Impression:This object looks like a smudge of light.
Chart Number:No.187(Extract taken out of "Atlas of the Southern Night Sky").
Size:26mm Eyepiece:Field Of View:57'/14=4.0'.
20mm Eyepiece:Field Of View:50'/12.5=4.0'.
Size in Arc Minutes:4.0'.
Planetary Nebula is 4.0'*1.3'.
Brightness Profile:The central nucleus of this planetary nebula grows slightly brighter compared to the far outskirts of this nebula.
Challenge Rating:Very Difficult.
At 167*I have noticed a very faint oval shape of light which is well defined.By making use of my OIII filter threaded onto my 9mm eyepiece the shape of this nebula is easily discerned whereby I noticed that this nebula has a large reddish blur of light.By using a Ultra High Contrast filter at both 167* and 214*less surface detail of this nebula is discerned.This planetary nebula has a low surface brightness which means that this is a large planetary nebula whereby the light is spread over a large surface.
