Astro trip to the south

Posted By Inge Skauvik
I have a Portaball which can be collapsed to a size small enough to bring along on the plane.(For details: www.Mag1instruments.com)
For the one who doesn't have this possibility there are a few persons down there who specialise in astro tourism and who have scopes available for rent.

An anniversary session

Posted By Inge Skauvik
Hello Zack,

Nice post. Interesting to note that you see NGC7662 as white (but why not a white snowball?). After all the colours of emission nebulae are very elusive, and the visual impression may vary from time to time and person to person.

I can't recollect having spotted NGC7292. It is so faint that it should be considered a challenge for an 8-inch scope. Since you were able to spot it, I'm pretty sure you'll be able to make out much nice detail in the brighter objects, like M33, M51 and M101.

NGC7000

Posted By Inge Skauvik
I have never seen NGC7000 with anything less than 8 inches of aperture. In most text I have read about this nebula it is referred to as either a binocular object or an object for a big scope. But the optimum is perhaps an aperture in the 3 - 6-inch range.

I often observe this nebula together with the other nebulous patches west and south of it with my 12.5-inch. The region around the "Gulf of Mexico" is quite impressive with an O-III filter. However, lack of contrast makes it difficult to detect features in the northern part.

Campbell's Hydrogen Star

Posted By Inge Skauvik
I tried to find it, but couldn't identify it among the myriad of stars in the region. I'm afraid that the red colour is more difficult to make out in my 12.5-inch than in the 60-inch at Mt.Wilson.

Structure in NGC 7006

Posted By Inge Skauvik
I have always seen NGC7006 as a small, rather faint and perfectly round object. Maybe because I knew what I was looking for the first time I observed it. I tried to view it at high magnification once to check if I could see any hint of stars in it. Of course, this was completely out of question, and I can't say I noticed any other features either.

New Mexico Skies Night One, 2005/10/29

Posted By Inge Skauvik
Dave,
This must have been a fantastic night. How do galaxies look under such conditions and such an aperture? Can you make out the spiral structure for many of the moderately bright (9 - 10th magnitude) galaxies?

I assume that the double quasar just appeared as two points of light, but still it must have been a very special experience to expose the retina directly to those photons.

Question from a novice

Posted By Inge Skauvik
Interesting advice, guys,
It is indeed, true, when comes to knowledge of the binocular market I belong to the dummy community. During one of my few trips to the US I tride a pair of hand held binoculars (7 or 10 x 50) which fully demonstrated that there is a difference between brands although they look very much alike. I'm not sure, but I believed those were Celestron binos.
Maybe I would choose a pair of big binos on some kind of mounting.
I have never tried to measure my pupil size, but I work with exit pupils of 5mm without any problems with my Portaball.
I consider a set-up (including the mounting) within 1000$. Not being in a hurry I may very well keep an eye on the second hand market for a while.

Rio

Posted By Inge Skauvik
Dmitri,

I have been dreaming about both "The Silver Dollar" (NGC253) and NGC55 for years. How does the surface brightness of NGC253 compare with other galaxies?

Have a good time in Rio!

Rosette/2237 question

Posted By Inge Skauvik
It is possible to see the nebulosity of the Rosette in binoculars under excellent conditions. In a telescope with a narrow field of view and a magnificaiton of 50 or more, it is difficult to see the nebula without a filter. One trick is to rock the telescope slightly. In this way parts of the nebula may appear. With an 8-inch f/6 I could see the part north-east of the cluster in this way. The O-III filter works very well with the Rosette nebula. With an aperture of 12.5-inches several of the bok globules become visible, and in an 18-inch it is a marvellous sight. Even an 8-inch shows a considerable amount of detail.

Diffuse nebulae

Posted By Inge Skauvik
Auriga contains several diffuse nebulae. None of them are really famous show objects, but the easiest one, NGC1931 can be seen in almost any small scope. IC405, the "Flaming Star Nebula" is often shown on photos, but it is very difficult visually. The most interesting nebula of Auriga in my opinion is IC410. This is an emission nebula involved in the coarse cluster, NGC1893, which is easily located just west of the small asterism made up by 14, 16, 17, 18 and 19 Aurigae. It is very difficult to see without a filter but O-III works very well. In fact it reminds me a bit of the Crescent nebula (6888) in Cygnus.
