Hello everybody

I was a week on holiday on a darker place (NELM 5.5) than my hometown (NELM 4.5). Because I had to choose between my kids or my 12" in the car, I took my 8 cm refractor to observe the night sky :-)

Spring time = galaxie time. So I did some deepskysketching over several nights. Most NGCs were difficult to observe, except one: NGC 3384 (next to M105).

All the observations were made @ x43 or x79. HB and 8B pencils and blending stump, scanned and inverted.

Here's the first one: M101.

Hope you like it.

NGC 3389 is quite a catch from a mag 5.5 skies with a 3" telescope :bow: I had a look at this galaxy just yesterday from my 5.6 (SQM-L 19.10) backyard with an 8" telescope and it was invisible. Is the 5.5 skies an estimate or an actual measurement?

Jef,

I like your method of selecting which scope to bring. You made the correct choices. :)

Excellent captures. I love them all. Also the sketches nicely show just how well an 8 centimeter scope can do. :bow: :rainbow:

Oops, my typo!

Frank :)

I agree completly. A great choice in scopes and exelent sketches. I too have been having great fun with my 4 inch (102mm) refractor looking at galaxies this spring. I think it really takes us back to our roots using small refractors for deep sky observing. They do show us so much of the sky, more than you would think, since so many of us are using large (10 to 24 inch) dob's now.

wonderful set of sketches Jeff, thanks for sharing. NGC 3384 is fairly bright but catching NGC 3389 is quite an achievement with a 8cm scope!

very sharp sketches with a very modest scope, you have a great eye for dso, thanks for posting.

All of you, thanks for the nice words. It was a long time ago I did some deepsky sketching. Most of the galaxies are not very impressive in a 8 cm. But when you see a duo or trio it makes a lot of fun (in comparing and sketching).

About NGC 3389. I had never observed the galaxie before. My fieldnotes says "very difficult, can see once in a while a small, round glow". At Deepskylog there are some 50 observation of NGC 3389, the smalest aperture is... 15 cm! Because I have not the eyes of O'Meara, I think I saw a "ghost" in the night sky :(
Jake, the 5.5 NELM was a rough estimate (over 4 nights), not a scientific research. Maybe that night it was (slightly) better than 5.5. But not 6.5 anyway :(.

Jef,

Very nice to see one of these fine sketches on ASOD today.

Frank :)

Jef,

An excellent series of galaxy observations through your fine 8 cm refractor. These observations show the potential for moderate aperture instruments on galaxies and other DSO's. Thank you for sharing them with us all.

I am glad that you took your refractor and the children!

Carlos

Carlos, the William Optics Zenithstar is a very good instrument (compared to the ETX-70 that I used before :)). Small or big telescope... it doesn't matter. You just have to choose other objects/scenes to sketch.
