Hey Mak -

I stumbled over this Pdf. yesterday and thought of you. You might enjoy the history outlined in it:

Comparison Test of TVPlossl vs Brandon.pdf

I liked it and tossed it in my file on EP's.

'ta,

Dave

 

Greetings Comrade Mak -

That's great news for you regards using the newly popularized compression-rings with these flared tubes! That must be quite a load off your mind. And thank you for the Prisoner's Penny-Farthing bicycle. Otherwise known as 'The Ordinary' over here. As a bike-mechanic, I love these older-model bicycles! I always have an eye out for these in particular. I've never riden one, and would need to review a 'How-To' manual. I'd want a handy bale of hay to act as my brake!

I really like my Antares Twist-Lock Adapter 2" to 1.25" adapter. Perfect for using just an easy hold on an EP - without over-tightening. And much less $£ than the ubiquitous Baader offering. And now Orion (USA) has also jumped on the 'band-wagon' with their own - for much more £$ than the Antares. Oh yes - the Antares has excellent threads for a 2" filter. Nothing more annoying to a Filter-Nut (like you've become! ) than botched threadings.

So I do believe the compression-ring is here to stay and it's use will grow. I hope the price on these drops as the usage expands.

Catch you later -

Dave

 

Agent 99 Mak -

I've heard and read the Penny Farthings were actually easy to get going - and very fast with good cornering if you learn to lean to facilitate turning. The odd length of the wheelbase made this necessary. Of course - crashes would help you learn this rather quickly!

Glad you're experiments with the flared-barrels are showing success! I hope you write this all up and submit an article to Sky at Night - or whatever your local Astronomy-Magazine is over there! And ours as well.

My shoe is ringing again,

Dave

 

Yes - the SWAN is specific in passing the cyanogen-bands, aong others. Here's a few transmissions:




And where this one crawled in from - I haven't a clue:




So it will work also as a pseudo-OIII filter. I'm glad that Lumicon didn't crash & burn. Then there'd be no current production of the SWAN-Filter. And something tells me that comets are going to increase in popularity in the 'Observers' Favorites.'

I love to explain to people that Cyanogen (where we get the name 'Cyan' from as a color. And it was discovered to be a derivative of cyanogen that creates this color) - is a deadly poison in it's pure form to life that has need for oxygen and uses blood to transport the oxygen throughout the body. The cyanogen pushes the oxygen out of the blood and suffocates the life-form.

While being a deadly poison - cyanogen - brought by comets - seeded the early Earth with the carbon and nitrogen required to create the molecules that bring forth life.

It is also where we get the name 'Cyanide' from. And why I coined the expression: Cosmic Cyanide to describe the make-up of many comets.

Pouring rail here all day. Wish I had a canoe....

"How does a coracle grab you?"

With it's tentacles & suction-cups?

I know the EP I want to hunt Comet Johnson down with in my ST80: My 40mm Plössl HighLight I got in 2003. This would give me 10X to start with. Then I'll up the ante to around 50X, depending on conditions. I may also use the 40mm Plössl and drop it into my 5X GSO Barlow and see what that does for me.

And, of course, I'll add my SWAN and see what this whispers to me!

'Ta,

Dave

 

We shall see!

If I do, then know I have another telescope I can fall-back to! I'll look and see how my newer mini-scope does in seeing the 40mm in the scope.

Soon to bouncing my view off the Moon. Then MARS!

Re: #38 Dark Blue - I've never even seen one. Leave alone tried such on anythings' tail.....

But it looks interesting. For now I'll settle for some warm(er) nights and no more rain. But more is on it's way - so sayeth the Doppler-Radar.

Ah! I now remember what I've forgotten to do - fish another person out of the Dark Lords' Manner whom has been corrosponding with me on 12" Meade LX90 v. Celestron 11.25" SCT. I've explained the mechanical idiocy of Meade - though their UHTC & ACF are incredible - and what he'd likely wish to do about same. And he's feeling brave enough with tools to conquer them.

So we may have another face/name in our midsts if he's brave enough to check us out over here in the Untied Snakes. Anytime I mention another forum that's in the US - people cringe: Visions of RowdyFights and the need for a Whip & Chair!

Back to watching a new horror-movie: The Rise of the Trailer-Trash!

Now you've got me curious about the #38-Filter! Curses! Foiled again!

That Pdf. on filters is interesting. It rather resembles the one Agena has for their collection of color-filters. But are you absolutely certain it doesn't have a virus? Or even a case of hayfever? The sniffles?

Regards trailer-trash - also known as 'white-trash' - here's a stereotyped-example. High times down at the Average-American Trailer-Park:




It should be captioned - "Stay in School Kids! Or You'll Never Afford the Good Life Like Bubba!"

Well it was about 80°F. here today. And still nice & warm this evening. And as soon as the Sun set? CLOUDS! SOLID! See what happens when you mention filters? Of course I share some of the blame. I just updated the comet-file in CdC!

Alex of Stellarium-fame just yesterday added an extended data-base on DSO's - more that 1,000,000 entries. I downloaded the updated file - and CRASH!! It froze-up solid like a cloud. So I rolled it back to the 15.2 - thankfully all was well again - my settings were undisturbed.

Off to report this phenomena to Alex and his co-conspirators! See ya 'round the Trailer-Park.

'Ta,

Dave


ps - I needed the name of 'Teleskop Service' to look up some things. Thanks for providing it!

 

I never watch TV-shows like that. I'd need a psychiatrist if I ever find myself doing so.

Regards the disparity of the SWAN v. #38? Curious, isn't it? It does say, in the literature, that the SWAN is good for certain tails of comets - so not ALL comets. The #38 says it works on bright & large comet-tails. It is known that not all comets are putting out lots of cyanogen in their tails. So that would explain why 'certain' tails respond to SWAN-filters. With the #38, it sounds like it's working on showing the contrast of where there is, and is not, a tail that's bright enough.

I'd think if the comet wasn't bright - the #38 might well make it disappear altogether. So as you have decent weather - I'll leave it up to you to see what the #38 will do. I'd be satisfied just to see Comet Johnson myself. This weather has got to give.....someday.....

Did you have thrilling and fun-filled 'Election-Day?'

Dave
