Saturn Template

Posted By Sol Robbins
Hi,

Attached is the Saturn drawing template I currently use. Its rather large image scale is what I am prefering to use lately.

Feel free to print it out and/or resize it for your own needs.

I think that the ALPO site has some in an "observation form" format. I prefer to make my own based on what I see in a scope.

I usually use a high quality photo printer paper with a smooth matte finish.

Best, Sol Robbins

Jupiter Template

Posted By Sol Robbins
Hi

I might as well upload my Jupiter template. It was generated from one of my drawing and then faded out with Photoshop.

I would recommend that you take a ruler and *very lightly* pencil in edges for the NEB and SEB in a barely seeable fashion. This might help a little bit in keeping proportions close to right. These bands always present themselves a little differently fom night to night.

Hope this helps, Sol Robbins

Posted By Sol Robbins
Hi,

I had some some time to observe Saturn last night and also check out my new EQ head.

Seeing conditions and transparency were good, though the transparency did not last.

Enceladus was observed as well. Nothing unusual in this observation except for the B ring ringlet distribution. Also, as per Carlos' observation the SEB appeared mottled.

Jupiter Sketch Feb. 20, 2005

Posted By Sol Robbins
Hi,

Finally got my first sketched observation regarding Jupiter with good seeing. My Apogee H.D. EQ head, same as the Meade LXD55, worked well as my CG5 mount took a spill and became unuseable.

There is a lot of activity in the STB with what I believe is the BA oval about halfway between the following limb and the CM, as well as a couple of others. On balance, the SPR appears a little lighter than I remember.

The SEB appeared mottled and a dark rift was prominent.

The NEB also has a segmented but prominent dark rift that's punctuated with some light spots. Festoons were fuzzy with the most prominent one just following the CM.

Jupiter Sketch April 10, 2005

Posted By Sol Robbins
Hi,

Finally had decent seeing for Jupiter observing.

SEB and NEB show major disturbances. Very dark and large festoon at CM on NEBs. Just following this festoon is a rather large oval disturbance. Rippling throughout the NEB and attaching to NEB rift.

Jupiter Sketch 04.18.05

Hi,

I had very good seeing conditions for Jupiter tonight.

Again, lots of activity in the SEB & NEB.

Used my 9.75" reflector on an EQ Mount without filter.

Jupiter Sketch 05.09.05

Posted By Sol Robbins
Hi,

I had decent seeing and very good transparency for this Jupiter observation/sketch.

I used my 6" Skywatcher refractor.

GRS showed detail and the SEB rift following was very bright, long and well defined. I spent most of my sketch time sussing this out. GRS color was articulate but a pale pastel-like rust color

NEB had lots of marbling and 3 light areas noted. One in the NEBn on the preceding side. The other 2 straddle the CM equidistantly near NEBs.

Festoons were the graceful blurry kind with dark bar-like appearance at their bases on the NEBs

The SPR appeared somewhat calm.

I used my usual 4H and 2B pencils, trusty eraser shield, and blend with my fingers. The darkest areas were very lightly gone over with an 8B pencil.

Mars 07.03.05

Posted By Sol Robbins

Hi,

I had had relatively good seeing for my first observation of Mars. Atmospheric dispersion would come and go but still, Mars showed a good amount of detail. At this point Mars' apparent diameter is quite small at 9.4".

I used my 6" refractor at 400x with a Sirius Optics VFS filter. I consider some settings on the VFS filter to the best filter available for Mars viewing.

I sketched mostly with a 4H pencil and a stump. If Mars is showing this much detail now, I can't wait wait till later on during this opposition as Mars is quite high in altitude compared to the 2003 opposition.

Best of luck to everyone with your own observations.

Planetary Observation and Sketching

Posted By Sol Robbins
Hi,

After 2 decades of observing,I have just recently started to sketch the planets for the last month and half.

I reading through the messages, I see that some of you are drawing in color. Right now I an going for detail and for right now that necessitates the use of filters as a means to more easily uncover them.

Additionally, rigging up a white light source to draw by that would allow for for showing what I had drawn as close to the same contrast as when I saw the finished drawing after it was brought into normal roomlight was my first big obstacle. My early drawings were looked too dark when brought inside. Now I use an old polarizing filter over a mini Mag light to control its brightness.

Attached is my most recent sketch of Jupiter. This only my second attempt of the great planet.

Thanks, Sol Robbins
