Les I also like this object in the same area as the Pencil;

Cr 197 (08 44.7m -41 deg 17') and Gum 15 / RCW 32 (08h 44.6m -41 deg 17') is an open cluster containing the small bright nebula known as Gum 15 which surrounds the multiple star of I 815. Surprisingly missed in AOST2, it can be found some 2.2 degrees North of the wide pair of 4th magnitude d Velorum / HJ 4133 (08 44.4m -42 deg 39') and 0.8 degrees N of NGC 2671 - our Pencil - which is an open cluster..
This open cluster covers about 17 arcmin of sky whose nine stars, whose brightest four stars make up the multiple 1815. At 6.7 total magnitude, its singular blue star, followed by the remaining yellow stars, are classed as “3 3 m n” - the “n” being the bright nebula Gum 15.
South African visual observer Auke Slotegraaf claims to seen the clusters' shape as triangular in 11×80 binoculars, but comments it was "... Not an easy object." I looked for this in 7×50 binoculars and did not really see much. Auke also observed the cluster in his 25cm (10") f/5 Newtonian at 30x.. Describing it as a "typical Collinder cluster", he describes its shape as;

"... reasonably large and the brighter members seem to lie in an uneven, curving V-shape grouping of l l stars, 5 of which are pretty bright. The 'V' points north to a very unequal double star, [I 815]…"

I 815 (08 44.7m -41 deg 17') is the multiple star whose four components are listed as AB (7.3v and 11.5v, 4.4 arcsec 2 deg), AC (7.2v and 13.3v, 8.3 arcsec 130 deg) and AD (7.2v / 11.0v 35 arcsec 225 deg). I 815 appears on Map 397 in Uranometria 2000.0 drawn with the "box" of nebulosity of superimposed Gum 15. The AB and AD pair was first discovered by Innes in 1911, and AD is the widest an most easiest to see. The AB system can be seen with 10.5cm with care and is easier in 20cm - the problem being the magnitude difference. AC is slightly more difficult, and should be visible in 20cm under good seeing and moderately high magnification. Again, the five-odd magnitude difference made it hard combined with the faint 13.3 magnitude. I glimpsed I 815 C once in 30cm in moderately good seeing and made a rough sketch. This later star was discovered by Innes in 1933.
All stars in this system are bluish-white, likely matching the spectral class of B3/5 II of the primary. Little has changed in the positions since discovery, and it is uncertain if these stars are dynamically behaving like multiples or as open clusters, but they certainly must be associated. 1 815 certainly adds to the Cr 197's appearance.

As for Gum 15...

"Gum 15 (08h 44.7m -41 deg 17') is the faint emission nebulosity centred on the primary 7.3 magnitude star of the double I 815, of which, can be imaged some 10 arcmin around it. Telescopically in the 30cm it appears as a faint haze about 1 arcmin across, which is significantly enhanced with averted vision. The proximity of the component stars make it a bit of a challenge to see.
It is possible that 25cm, or even 20cm, might be able to see this nebula, but larger apertures may see a little more nebulosity. Either way, to see Gum 15 you will need dark and fairly transparent skies."
