SKETCH: M13 and NGC 6207

M13 with a 4 inch telescope



Telescope: Astro-Physics Traveler EDF 105mm F/5.8
Eyepieces: Televue Ethos 8mm
Transparency: 3/5, 21.3 SQM
Seeing: 3/5
Date: 30/06/14

Notes: Lots of 14th magnitude stars coming in and out. This aperture appears to be the limit to observe M13 seriously. NGC 6207 is small and faint. It has a very stellar nucleus.

SKETCH: Veil Nebula

Veil Nebula with 4 inch telescope

Telescope: Astro-Physics Traveler EDF 105mm F/5.8
Eyepieces: Televue Ethos 21mm
Filter: DGM NPB
Transparency: 3/5, 21.3 SQM
Seeing: 3/5
Date: 30/06/14

Notes: Star field too crowded, it was impossible to paint all the stars visible. Pickering triangle was very faint, and difficult to see any structure.

SKETCH: NGC 4631, 4627, 4656 and 4657

NGC 4361 and friends with 4 inch telescope

Telescope: Astro-Physics Traveler EDF 105mm F/5.8
Eyepieces: Ethos 10mm
Transparency: 4/5, 21.3 SQM
Seeing: 4/5
Date: 03/05/14

Notes: A very difficult observation. NGC 4657 has two faint patches that begin to show the "Hockey Stick", but NGC 4656 is much more easier to see.

NGC 4631 is big, patchy and some dust clouds are showing here and there. There are also some "bright" patches, but not easy to see. NGC 4627 is very faint and the glow from 4361 makes it harder to see.

SKETCH: NGC 4565 and 4562

NGC 4565 with 4 inch telescope


Telescope: Astro-Physics Traveler EDF 105mm F/5.8
Eyepieces: ZAO II 16 mm + Barlow Abbe 2x
Transparency: 3/5, 21.2 SQM
Seeing: 3/5
Date: 02/05/14

Notes: The dark lane was best seen with smaller exit pupils (even under 1.0mm!). NGC 4562 is extremely faint tonight (magnitude 13,7).

SKETCH: M104

M104 with 4 inch telescope

Telescope: Astro-Physics Traveler EDF 105mm F/5.8
Eyepieces: Televue Ethos 8mm
Transparency: 3/5, 21.3 SQM
Seeing: 1/5
Date: 05/04/14

Notes: Very high humidity, had to observe inside porch to finish sketch with the ota not fully thermally stable, so everything was boiling.

SKETCH: Leo Triplet M65, M66 and NGC 3628

Leo Triplet with 4 inch telescope

Telescope: Astro-Physics Traveler EDF 105mm F/5.8
Eyepieces: Televue Ethos 10mm, Pentax XO 5mm
Transparency: 3/5, 21.2 SQM
Seeing: 2/5
Date: 23/03/14

Notes: Clouds passing by, far from good conditions. I only carried with me two eyepieces that night, so I didn't have all the magnifications I needed to do the sketch.

M65 had some strange S shape with the Pentax XO 5mm. Looking at the photographs and sketches from others, it seems it's a internal arm that it's slightly brighter than the galaxy.

It's really hard to get details from the galaxies, so patience is absolutely needed here.

SKETCH: M51

M51 with 4 inch telescope

Telescope: Astro-Physics Traveler EDF 105mm F/5.8
Eyepieces: Televue Ethos 10mm, Pentax XO 5mm
Transparency: 3/5, 21.2 SQM
Seeing: 2/5
Date: 23/03/14

Notes: Clouds passing by, far from good conditions. Some hard to see faint bright structures at high magnification. Bridge can be seen as a faint streak with lateral vision. Only one star visible tonight.
