IC 418 is a planetary nebula in Lepus ; magnitude: 9.3 ; size: 3.5"x5.5" ; known as the Spirograpgh nebula because of the beautiful photo from the Hubble space telescope. Another known moniker is the Red Raspberry, because of it's red hue. I have only observed the red color once, a few years ago in a fellow observers 20 inch Dob, on a night with excellent seeing. This planetary is bright but small, so high magnification is needed to see the shells of nebulosity. It is elongated with a bright 10th magnitude central star. I used a 4.5 Delos eyepiece at 352x magnification with my14.5 Starstructure Dob f/4.3

Nice sketch of this little bright planetary.
Have seen but not as well as you have sketched it
With a clear night and Lepus on the meridian I'll need to look again at high power.

Fine sketch of Spirograph Nebula (IC 418) .

Nice sketch Raul. Unfortunately this one is low in my sky and increasing magnification can't be done on most nights.
Sounds like a nice challenge to look for the red hue.

I've seen this one, looks a lot like your sketch. I could not make out its red hue.
