I am unable to really identify anything with my previous work on a sheet and the junk maps I find on the internet..

I think that the darkest shade on my sketch "c" could be a part of Mare Sirenum...

 

I really don't know how accurate is Stellarium to show the right face of Mars.

I have no way to verify this currently.

 

@Nebula, I have two free programs (apps? Am I showing my age?) that I find invaluable: Virtual Planet Atlas, and Virtual Moon Atlas. I have been using them for years and find that they are easy to use and very informative. They are free downloads. If you like observing planets and the moon you may want to download these programs and give them a try. Easy enough to delete if you don't like them - but I'm sure you'll keep and use them.

As for filters, I find that for me, the best all-around Mars filter is the Baader Neodymium (M&SG) filter. I have both the 1.25" and 2" sizes for imaging and visual use. For colored filters I have inexpensive filters in light and medium RGYB. Mine are the old Meade brand. I suspect the GSO, sold by Agena, are OK.

Your sketch is good, capturing Martian surface features, as well as the included information.

Thanks for pointing that out, Mak. I'm using Windows 10.

According to this report, the storm has peaked and is slowly winding down (hurray!). It has impacted the solar-powered InSight probe but not the nuclear-powered Curiosity and Perseverance probes. NASA reports that these storms are particularly numerous and large during northern fall and winter on the Red Planet (which is ending):

Aren't we all, LOL!

 

I would benefit from it!

Congratulations @Mak the Night for the premium Orange filter. My 82a filter was not so impressive tonight compared to my Baader neodymium, the low quality of the glass would obviously cut my total resolution which is a big deal when then amount of details is already very low on Jupiter.

The Mars atlas from #46 looks cool. It's called simply Mars Atlas?

 

@Mak the Night I found a 82a Lumicon, on Agena, I will use it with a 9mm and 12mm Xcel Lx, the Fujiyama OR-HD and the 6mm Delos.

Do you think that Lumicon will screw well to these eyepieces?

My idea was to buy premium 80a and 82a at the same time but the 80a is BO, it is not really the end of the world because my first choice was really 82a for Jupiter. Today I compared my GSO 82a with the Neodymium filter, a naked eye test and it's VERY different, neodymium will add a lot of red to the views even if the filter is blue, but the 82a will really turn the image blue and contrast the reds, both have similar effects on the reds but with the Neodymium, the image is MUCH sharper and cleaner, very comfortable to look through, it truly is an incredible filter.

These are my naked eye observation from today.

I'll have to pass on the Apple Mars atlas and the appstore.

 

@Mak the Night Hemmm on the website it's the older version, from the image. I tried to find, without success, the wavelength of Wratten 82a, it's nowhere to be found on the internet.

But I am still attracted to the Baader solution, it's more expensive but it might be as good.

470nm they say about it, it's almost a cyan filter.


Do you have it?

 

@Mak the Night Thanks for your opinion on this again. I ordered the Lumicon 82a - very light blue filter from Agena this morning. I think it will go along well with my Baader Neodymium as a second option for Jupiter (Maybe the moon also and other planets)

If it has the same transmission at my GSO, 73%, it's not going to be too aggressive just like neodymium, that's what I hope but with a premium quality filter.
