1333 1491 1579 1624

[glenc]

This morning I looked at some nebulae with my 12" Dob.
NGC 1333 a faint reflection nebula.
NGC 1491 a faint emission nebula, used a UHC filter.
NGC 1579 was best at high power with no filter.
NGC 1624 a faint cluster/emission nebula, used a UHC filter.

I tried without success to find Hind's Variable Neb = NGC 1555, length = 1'.
A SKY-MAP.ORG image is attached. The orange star next to the nebula is T Tauri, it varies from magnitude 9.3 to 13.5
Here is some history for 1555: http://www.klima-luft.de/steinicke/ngcic/persons/hind.htm
and recent mags for T Tau: http://www.aavso.org/cgi-bin/newql.pl?name=T%20Tau&output=html

I also tried for IC 2162, I think I saw it, I will check again when it is clear.

Tried NGC 1555 again last night, still not seen for sure. Is it visible in a 16"?
SKY-MAP.ORG is great for getting images of an object, also http://www.wikisky.org/

NGC 1555 = Hind's Variable Nebula = Ced 32b = Sh 2-238 = T Tau = HH 155 = PP 17 RA 04 21 56.8 dec +19 32 04 Size 1

17.5": this refers to Hind's variable nebula, illuminated by T Tauri (9-13). At
100x and 140x (unfiltered) an extremely faint haze was highly suspected on the W
or WSW side of T Tauri (mag 9) in the direction of a mag 14 star to the west or
slightly south (this star is Struve's N1554). No details were visible at 100x
(did not appear as an arc) but a sketch made at 100x exactly matches the
orientation of the nebulosity with respect to T Tauri. Nebulosity was not
visible at 220x and no nebulosity was noted following T Tauri.
This is the famous Hind's Variable Nebula surrounding the variable T Tauri,
discovered by Hind in 1852 with a 7-inch refractor.

Glen, since you post I have tried on a couple occasions but the weather and seeing have not been up to the conditions needed to see this object:(
I will keep trying:thumbsup:

Thanks Ron, 1555 seems to vary a fair bit in brightness.

Today's APOD is NGC 1579. http://antwrp.gsfc.nasa.gov/apod/ap090130.html
"Colorful NGC 1579 (http://dg-imaging.astrodon.com/gallery/display.cfm?imgID=163) resembles the better known Trifid Nebula, but lies much farther north in planet Earth's sky, in the heroic constellation Perseus (http://www.hawastsoc.org/deepsky/per/index.html). About 2,100 light-years away and 3 light-years across, NGC 1579 is, like the Trifid (http://antwrp.gsfc.nasa.gov/apod/ap070813.html), a study in contrasting blue and red colors, with dark dust lanes prominent in the nebula's central regions..."
This image is from wikisky.org: http://picasaweb.google.com.au/dunlop1826/NGCNebulae#5281634246584432066
It is about half way between M45 and Capella.

I don't know if you've noticed, Glen, but you look like you have the trail of an asteroid in your piccie...about 1/3 of the way from the left side of the piccie and a bit more than a 1/10 up. Quite bright too.

I like this picture of NGC 1333 http://antwrp.gsfc.nasa.gov/apod/ap090418.html

[glenc]

I still have not seen NGC 1555.
Here is an APOD image: http://antwrp.gsfc.nasa.gov/apod/ap090803.html

Glenn and all
Here is a useful extract in pdf form from an article written by me on the nebulosities and the star T Tauri itself.
Telescopically the region is fairly dismal even though the work done has revealed much about star formation.
Hope it is some help.
Cheers

Note: When I first read the title, I thought you were giving a credit card number! :lol:

Thanks Enchilada for an interesting article. It would be interesting to image NGC 1555 on a regular basis to look for changes.
