A pic of the author


A recent picture of me setting up one evening. Because of a number of trees nearby, the part of sky I observe is usually >60deg North: circum-polar observation. Still planning that home observatory…

Luna Winter


I retrieved the telescope from storage for the first time in two years. The Moon was a good object to practice on and test the equipment: waxing gibbous phase.

I have been looking through some older images and found these: they are from different times in 2014, and I simply increased contrast and adjusted brightness. The nebulousness is quite faint in these images, so click on them and get a close look…

Part of the Crescent Nebula: an emission nebula in the constellation Cygnus, about 5000 light-years away. This exposure captures part of it:

Clear night with the July 4th fireworks. I used a Zhumell skylight filter but it is not very effective. Soon purchasing an OIII filter… Here are a few grainy images.

Coma Berenicis objects


Study of Coma Berenicis. The night sky was mostly clear with thin clouds intermittent. High light pollution: not at my dark site tonight. This night I was using a skylight filter from Zhumell: it did cut down somewhat on stray light and gave a colorful tinge to images. Each image is 10 exposures at 15-25 seconds with an ISO of 800. In order, we have M64, binary system Cor Caroli, cluster M53, and a favorite edge-on spiral galaxy NGC4565.

COR COROLI_LIGHT_10s_800iso_b

Cor Caroli (α CVn, α Canum Venaticorum, Alpha Canum Venaticorum) is the brightest star in the northern constellation Canes Venatici. It is a binary star consisting of two distantly separated components. The name Cor Caroli means “Charles’ Heart”, and was named in the 17th century to honour the King Charles I of England who was beheaded in 1649. Cor Caroli is a binary star with a combined apparent magnitude of 2.81. The two stars are 19.6 arcseconds apart in the sky and are easily resolved in small telescopes. The system lies approximately 110 light years from Earth. The brighter of the two stars is designated α² Canum Venaticorum, the fainter α¹ Canum Venaticorum. Reference: Cor Caroli. 2014.

Blocking the sky

A couple of jets had flown over earlier causing this: right before my observing session. These are no ordinary vapor trails. They spread out slowly to the South for miles after the jet passed over.

Slooh pics 1/13/14 – 1/15/14


Here are some random images obtained from the Slooh telescopes in the Canary Islands. This is a nice service to have during the cloudy Winter months. Slooh does have it’s bad weather moments though, as this week has had some tricky clouds. Click each image to get full size.

Slooh costs $300US per year, billed quarterly.

Slooh session scheduled: NGC 504, 507


I have scheduled a session with Slooh telescope Dome 2 in the Canary Islands to take some 5 minutes of images of galactic clusters in Andromeda. Two clusters of which NGC 504 and NGC 507 are a part. I will post images when I have them on Tuesday 1/6/2014.
