Well our Internet (external phone-line) is still not fully working – they have extended the repair date from Apr. 30 to May 8 and now May 12/13 – but staying on longer now!

But on a wing an a prayer I am posting this; being part of a series of good seeing with Saturn and Mars over these past weeks – and unable to post anywhere……..

My useful sessions with Saturn this apparition amount to a mere six with May 2 and March 11 being the most productive. On the date of the drawing the planet never getting higher than 20º from here. However patience and persistence still delivers and I already was optimistic seeing-wise from an earlier good session with Mars.

I could see no activity, even in the best moments, but on other nights, especially March 11, some lighter areas in the NTZ were seen or suspected. I’m pretty convinced I truly got the hexagon last apparition. This was undoubtedly aided by an unusually light surrounding NPR; but this has darkened markedly now so any angular outline to the cap will be very challenging for me now I suspect.

Colour: for the globe I felt there was a preponderance of brass-tones – with shades from very tarnished to fairly polished! Even the apparently slatey NPC has turned out to sample as a deep muddy-brown shade as developed from my saved colour impressions/comparisons; and simply looks bluish by contrast – at least on my monitors!

David,

An outstanding observation and report on Saturn. You have captured the globe and rings very nicely. From my view of the planet recently I noted similar features over the globe and rings.Thank you for sharing to with us all.

Regards,
Carlos

David,

A very impressive capture of Saturn.
I have never considered pointing a telescope at Saturn so close to the horizon.
Your sketch is photographic in quality.

Frank :)

Thanks All for your compliments – much appreciated.

Frank:

I have never considered pointing a telescope at Saturn so close to the horizon.

Where I live now I am particularly favoured for a relatively higher frequency of good seeing at low altitude. My previous home (only 8 miles to the n’east) where I observed from (1961-76) was not so good in that regard. I guess part of that was I was looking toward (between/across) a row of houses over the back street. Here I have open country till our N.E/S.W. isolated row/street hides the s’west sky. Also we are considerably higher than land to the south.

So all I can say those who are similarly favoured: do not give up on low altitude seeing.

As an example attached is a 1990 drawing (I had no computers then) when Saturn was at -22º declination and 13º altitude from here! This was one of a series, re. the GWS, and published in two reports in the BAA Journal back then.

Thanks all again.
Dave.

Many thanks Norme.

Catching up on recent - no Internet - days I have beeen looking on various CN forums and note threads such as reflector v refractor.....well: I have a virtual 16" refractor in the D-K as attested by visitors who have looked through such instruments.

Also big scope v small: perhaps worth quoting Peek ("The Planet Jupiter" page 32) "A large scope can be stopped down.........; but it is impossible to stretch a 6-inch objective into a 12-inch". Not that I look down on 6" :grin: or smaller - I enjoy each for their own virtues!

However I resist particpating in those discussions - and the D-K (perhaps slightly a one-off) gives me a lot of light to 'play with' following various investigations.

Dave.

You know, in great seeing having a 6" has pretty much kept aperture fever at bay. It's been a real treat. But, man, what a view you have. Got the fever. :)

I look forward to more observing adventures when the next dry season rolls around. Keep up the great work, David.

A beautiful rendition Dave.

I appreciate the colour difference between A and B.

Outstanding sketch David! You have an incredible eye for these subtle details, and considering Saturn's elevation it is all the more astonishing.

Many thanks Chris, Rich.

Had a good view of Mars (16th) but hopes were dashed with Saturn with the seeing 'truer' to altitude on that occasion - oh well!

Our Internet seems stabilized now (at last) so hope to get some long delayed and recent Mars posted today - domestic tasks allowing, but soon hopefully. :p

Dave.

An excellent rendition David. I had some reasonable seeing last night in spite of the planet being around 15 degrees in altitude!

David,

An excellent observation and rendering of the Equatorial Zone (EZ) storm over Saturn in 1990. I remember observing this storm as well. I have attached a link to a similar storm over the EZ in 1994 imaged by the Hubble Space Telescope (HST) in 1994. Thank you for sharing it with us all.

Thanks Paul, Carlos.

I see a good few UK observers are catching Saturn in good conditions in spite of the low altitude – always thought my location could not be that unique. In spite of that I still have only seven sessions at this rather advanced stage of the apparition – don’t think I’ve less than 30 in any since 1964/65!

Thanks for the 1994 link Carlos – I independently ‘discovered’ :grin: that outbreak – Saturn seems to have gone mad after the 1990 GWS with much activity during that decade. I well recall one apparition with both Saturn and Jupiter up at the same time and for some weeks I had more CMTs for Saturn…!!

Having recently been reporting observations to the BAA for 1995-on to contribute to a Section Report backlog I have been selecting drawings to maybe post here as a montage for perhaps that whole remarkable decade if I can get the file-size right.

Still got that Mars stuff to post – but weather too nice to be sat at the PC – but forecast indicates I will be doing so tomorrow and will have decided by then on what and how to present!

Magnificent. Dave, this apparition many digital images seem to show a prominent greenish hue north of NEB. Have you ever perceived anything like that?

Thank you for posting your superb work, that's a great asset to this forum!

Looking forward to seeing your Mars observations and other Saturn drawings from that exciting decade, Dave. Don't forget to make a start on Uranus this year in due course ;-)

Regarding Uranus, will be.
It would be advisable to perform a meeting at London about the subject regarding remote planets, at the BAA.
Just a suggestion. Faithfully.

Oops not looked here lately……! :o

Thanks Ivano, Paul, Stan.

Regret the no show with those Mars obs. sidetracked once again with more darned obligations and such!

Ivano: I have to say that the N. Hem hues I am getting are far less vivid than some imagery I’ve seen. As I mentioned more like “brass”: on the green side of ochre – perhaps what Pete (Azure1961p) said, on my Solar System Forum thread, “olive[s]” might fit better.

As for Uranus: never forgot it in 5+ decades so what more can I say – actually on this thread: nothing! :grin:

Thanks again.

Dave.
