Mars July 9th 2005

Posted By Alan Friedman

Hi Wes -

Wonderful mars image!

Returning from a vacation away from computers - there are a lot of very interesting posts to catch up with.

Judging from the most recent images it looks like the two weeks has made a real improvement in the detail visible on Mars.

best wishes,
Alan

A beautiful and detailed image, Wes - I enjoyed seeing your shots from this last lunar cycle when I returned from vacation.

Hi Kirk -

A very fine image - I prefer the more subtle range of tones in the darker version myself.

Hi Jan -

A very nice image - was it difficult to get a bright enough image with your 180mm and red filter at f45?

Hi Richard -

Excellent image! I use this technique often - both on the moon and on Jupiter and Saturn. It does take much longer to process this way but it without using it there would be precious few nights in my location where decent results would be possible.

best wishes,
Alan

1st light Solarmax 90

Posted By Alan Friedman

Hi Luca -

Congratulations on your new filter. The 90mm is fantastic for observing and for imaging.
The sun has its own set of challenges - the choromosphere has very detailed features to record but they change rapidly. And it is especially hard to find moments of steady seeing during the day.

Sometimes it can work better to hand select a single or a small handful of the sharpest frames to average rather than to stack a large number of frames. A high resolution B&W camera works very well for the narrow H-Alpha bandwidth. There are many different ways to process and present H-Alpha images - Paul Hyndman and Greg Peipol both have very nice processing discussions on their websites.

I'm sure that very shortly you will be posting spectacular solar images for us to enjoy!

Trying the sun once more!

Posted By Alan Friedman

Hi Luca -

You've captured some lovely detail in this prominence.

I opened it in Photoshop and adjusted the mid range slider slightly to expose some of the fainter wisps. Also added a black disk over the bright solar limb - a technique that can make the faint prominence a little more dramatic.

best,
Alan

I think you should publish a new photographic lunar tourguide - it would get all of your subjects the respect they deserve!

This field is a great study in youth and age - beautiful job.
