GOTO from the seventiesPosted By Inge Skauvik |
That is what I call a REFRACTOR! Wonder what Jupiter looks like through one of those...

Never know what you can do!Posted By Inge Skauvik |
NGC5907 (Draco) is a very nice edge-on galaxy, and I think you should be proud spotting it in your 6-inch. Since you like 5907, you should also go for 4244 in Canes Venatici (maybe you will have to wait until next spring for it). There are more nice edge-ons in Canes Venatici. My favourite is NGC4631, very large and bright and nicely grouped with faint stars. In the same low-power field of view a fainter galaxy, NGC4656 (NOT the famous NGC4565 in Coma) can be found. It appears as a faint straight streak in my 8-inch. In a 12.5-inch a definite hook shape can be percieved. Maybe a keen-sighted young person can see this hook-shape with a smaller aperture.

Ideas?Posted By Inge Skauvik |
I usually promote double stars to people who claim to have exhausted their DSO capabilities. However, there are quite a few interesting planetaries around which are very bright, but obviously missed by Messier due to their near stellar appearance. The best know examples are probably NGC6543 and NGC7662 (Draco and Andromeda) and the Eskimo nebula in Gemini. NGC6210 in Hercules is another good one, and so is NGC7009 (I think this is the correct NGC number), it is located in Cygnus not far from the North-America nebula.
And when spring comes don't miss the great galaxy, NGC4631. It is easily seen in an 80mm refractor.

Your favorite Deepsky objectsPosted By Inge Skauvik |
From my location quite a few Messier-objects are out of range. M11 can be seen, but the sun interferes during much of the year. M22 is too far to the south, and so are M8, M17 and M20. My favourites according to your definition are:
Globular:
SC: M13
DF: NGC5053 ("Ghost" of M53)
Galaxy:
SC: M82
DF: NGC3190 group (Leo)
Gaseous nebula:
SC: Veil complex
DF: Crescent nebula (Cygnus, forgot NGC-number)
Open cluster:
SC: M37
DF: There are two rich distant clusters, one in Lyra and one in Orion, both hardly resolvable in an 8-inch scope, but appearing as an enigmatic glow, only visible under the best sky conditions. I don't have my maps and tables around, and therefore can't give you the NGC-numbers.
I consider them to be attractive, but difficult objects.

Horsehead nebula?Posted By Inge Skauvik |
There aren't any globules in other emission nebulae (e.g. the rosette)that are more interesting visually than the horsehead? The horsehead it quite a sight on photographs, but visually it gets more attention than it deserves in my opinion.

The BLue Snowball NGC 7662Posted By Inge Skauvik |
I think the chances of seeing NGC7662 as a ring in a 4-inch are small. Photos do, indeed, reveal some annularity in it, but even within the "hole" the surface brightness is so high that a larger aperture is needed to make it out from the rest of the nebula.
I always see it as a bluish disk. It resembles NGC6543 in Draco and the Eskimo nebula in Gemini.

Favorite Open Clusters?Posted By Inge Skauvik |
I love open clusters because of their diversity. If I want to show a couple of examples of open clusters to someone new to astronomy I will always chose among the following three:
Double cluster in Perseus
M37, Auriga
M11, Scutum
The last one is awkwardly placed for me, normally accessible only during a few nights in August - September. But it's a beauty in my 8-inch.
I have a few personal favourites:
NGC7789, Cassiopeia
M46, Puppis
NGC6946, Cepheus
NGC6791, Lyra
NGC2194, Orion
The first one seems to be everyone's favourite, and I have no problems understandig that. However, M46 and NGC6946 are also great objects, the first one is interesting with the small planetary involved (or perhaps a foreground object), the second one having galaxy NGC6939 in the same field of view. The two last ones are challenging objects even in an 8-inch. They appear as an enigmatic, unresolved glow behind a rich star field.

A change in observing habitPosted By Inge Skauvik |
I belong to the dinosaurs. One resaon is the fact that I have so few available hours under the stars available. Weather conditions are bad, continuous daylight form May to August etc. Therefore I feel that I have to use the observing hours for the delight of direct observing.
I enjoy, however, other people's work. Top left on my screen now is a photo of Jupiter taken with a TMB 8". I will never have the economy to get such a scope, but I have access of an enormous amount of material to enjoy for free.
Dear imagers, I have a suggestion. After playing with the technology for some time, why not add some science to it. I know about a few persons who make very accurate double star measurements with a telescope/webcam combo. I'm sure imaging can also be used by variable star observers and why not try imaging stellar spectra? Meanwhile I will take my telescope under the dark sky using my eye as a detector. Just for fun and personal satisfaction.
