Pen & PixelFigure 1— Edmonton’s Luca Vanzellacaught the rising Lenten moon onMarch 10 last year. Luca notes,“The RASC Observer’s Calendarcalled it the Worm Moon. Accordingto the Farmers’ Almanac, “as thetemperature begins to warm and theground begins to thaw, earthwormcasts appear, heralding the return ofthe robins.” I might prefer the CrustMoon, “because the snow coverbecomes crusted from thawing byday and freezing at night.” The imageis part of a time-lapse sequenceoverlooking the Alberta Legislaturethat can be seen atwww.vanzella.com/astro/astro/20080303_Lenten_Moon_Rising.wmv. Luca used aCanon Rebel XTi, 300-mm lens, ISO400, f/5.6 at 1/60 sec.Figure 2 — Stuart Heggieproduced this image ofCederblad 201, a dark nebulain the centre of Cepheus,using an SBIG STL 11000camera on an AstrophysicsAP155EDF Triplet Refractorwith a 4-inch field flattener.Exposures were 34x5minutes in L, 9x10 minutesin R, 7x10 minutes in G, and6x10 minutes in B. The bluepatch at the bottom of thepicture is the reflection oflight from the superimposedstar in the vicinity. Justabove the star is a darkpatch of heavier and moreopaque dust, while thebrownish colour to theextended dust ribbon is dueto the obscuration of all butthe reddest light from thebackground stars.62 JRASC April / avril 2010Promoting Astronomy In Canada
