Jeremy's is one approach, and a good way to start.

I use the method I named after the fellow who devised it, The Mellish Technique, after the late Scott Mellish. I wrote the article soon after my meeting with Scott, and he edited the article for me. It is stunningly easy to do & use. A small globular cluster that is just resolving in your eyepiece takes less than 5 minutes, including a myriad of tiny pin points of barely resolved stars.

The sketch I did of Comet Lemmon with 47Tuc took less than thirty minutes to complete. What took longest was the individual stars within the field of view. The cluster & comet less than 15.

Jen, tip, try out the technique using the same photos I used to do the demonstation sketches. You'll find the demo pics in the Addendum, "sketching practice" at the end of the article. You'll also pick up some more tips from the "building layers" and "star brightness range".

Nope, I never process any sketch in any way. Every "image" you see of mine here is only ever a straight photograph of my work. Always.

The only "processing" that takes place is I take half a dozen photos of my work, with a fixed exposure & varying only the aperture of the camera, then select the photo that best represents my work. Nothing more.

Jen, does look like you did a good raid on a shop,

First targets? No. 1, the Jewel Box - without question.

No. 2, Sombrero galaxy.

No. 3, a small GC.

But, before you head for the scope, do a few practice pieces with the images I used to produce the article with to familiarise yourself with the handling of the materials. You will see just how quick, easy and effective the Mellish Technique really is.

Clear skies & sharp pencils,

Saturn, the Ring Master

Hi all,

I had a look up the night sky tonight, and I had a suspicion that even though transparency wasn't great, the atmosphere was in good nic to punch the magnification. And it was!

Saturn was my sweetheart tonight.

My trusty 8" f/4 scope was my weapon of choice. Sets up in 1min, and I didn't feel like setting up the C8. With the f/4 ratio, tonight was the first time I really got to use my 2X 2" ED Barlow - I've only had it for a year, . But it was the right tool for the job tonight. I combined it with my 5mm Hyperion and 360X was on offer. And tonight Saturn was tack sharp with very little thermal disruption.

A lot of detail was had. The A ring was for once noticeably darker than the B ring. The Cassini division was a delight to follow, just slipping out of definition as it crossed right in front of the gas giant's disk. The C ring too was plainly visible on the inside. The cloud structure was easy to make out. The equatorial banding was darker, and a little streakish/banded. And the polar region a little darker too.

Of particular delight was to notice the softening of the disks leeward side from the sun's direction. It gave the planet a rather impressive 3D effect. And being just past opposition, a very thin strip of the shadow of the disk could be seen being cast across the rings. On the near side, a nice little flaring of the rings shadow on the disk could be noticed on the disk's limbs. It was a very nice session tonight, spent on this Ring Master.

Size of sketched disk approx. 20mm.

Object: Saturn
Scope: 8" f/4 push pull dob
Gear: 5mm Hyperion plus 2X 2" ED Barlow, 360X

Lovely description and very nice sketch. Makes me think about pumping the power in my new 8" f4!!
Just a minor point but shouldn't the power be given as 320x? 200x4/5x2=320
