Hi everyone! 

 

After getting a new AD10 for Christmas (had a One Sky before that) I decided to try sketching! The desire to see the Orion Nebula was the original impetus for getting into telescopes in the first place so I figured it was a good place to start! I will have to invest in a better light though because my only red light is very bright and holding it while also juggling a clip board and pencils/tools was difficult. Any suggestions? 

 

Date: 1/20/20

Time: 6:45pm

Instrument: AD10

Aperture: 254mm

Focal Length: 1250mm

Eyepiece: Orion Expanse 9mm

Filter: Orion Ultrablock

Conditions: Clear, Very Cold

That is a very nice sketch, never mind it being a first sketch.  Lots of fine detail.

 

You ask for advice, I have a few:

1. Invest in a suitable table.  It doesn't have to be much - a small folding table at the local big box cost me about $20.  

2. Lighting - Lots of people have lots of different solutions.  My first success was a clip-on book light (look for these at Barnes and Nobles or the like), with the lamp covered in red transparent tape.  You may have to get creative.

3. Maybe try a lower power eyepiece? Something around 25 to 30 mm will brighten diffuse targets and put more of it in the field of view.

4. Keep at it! You are off to a great start, and I look forward to seeing more of your efforts.

 

Cheers!

WolfFang,

 

Welcome and you arrive bring a gift. Excellent sketch of M42/43.

You need to get the red flashlight out of your hand. Perhaps a clip-on to the clipboard.

I use this one which works well. I got it at a book store.

Thanks! I'll have to get one of those clip on lights! Follow up question (I hope you don't mind!) what is the scale everyone is using here for seeing. I've seen stuff like 2A and I can't find what that means anywhere

That would be the Pickering scale. It goes from 1-10.

 

https://www.skyandte...cale-of-seeing/

 

1 — Star image is usually about twice the diameter of the third diffraction ring if the ring could be seen; star image 13 arcseconds (13") in diameter.
2 — Image occasionally twice the diameter of the third ring (13").
3 — Image about the same diameter as the third ring (6.7"), and brighter at the center.
4 — The central Airy diffraction disk often visible; arcs of diffraction rings sometimes seen on brighter stars.
5 — Airy disk always visible; arcs frequently seen on brighter stars.
6 — Airy disk always visible; short arcs constantly seen.
7 — Disk sometimes sharply defined; diffraction rings seen as long arcs or complete circles.
8 — Disk always sharply defined; rings seen as long arcs or complete circles, but always in motion.
9 — The inner diffraction ring is stationary. Outer rings momentarily stationary.
10 — The complete diffraction pattern is stationary.

 

Another scale frequently used is the Antoniadi Scale

 

1. (I.) Perfect seeing, without a quiver.
2. (II.) Slight quivering of the image with moments of calm lasting several seconds.
3. (III.) Moderate seeing with larger air tremors that blur the image.
4. (IV.) Poor seeing, constant troublesome undulations of the image.
5. (V.) Very bad seeing, hardly stable enough to allow a rough sketch to be made.
Note that the scale is usually indicated by use of a Roman numeral or an ordinary number.

BTW Wolffang - you might want to alter your profile to show your location.  This may help us in conversations about weather, seeing, outdoor gear, etc.  :)

Thanks for all of the support everyone! It means so much! 

Frank - I will be sure to make note of that scale from now on when I'm out. Thanks!

 

perfessor - Adding location now. Thanks for the heads up!

You grabbed a lot of detail for a first sketch. Very nice. You picked a tough one to sketch. :)
