Too many

Ordered a copy today, looking forward to using it.

I've had my 12" Dob for about 7 years and my 6" Newt for about 5 years, both have been kept in the summer house, neither have been cleaned as both mirrors still look fine in fact the 6" still looks like new. The 12" mirror dews up during the winter months but the 6" has never dewed up, this probably explains why the 6" still looks like new.

I've replaced the Ethos eyecup with a winged eyecup that came with a Morpheus eyepiece which I find more comfortable.

I use it in the up position.

That's a great scope, I spent many a happy hour with this most useful long Newtonian. Nothing wrong with optics to get such a tight split . Enjoy !

Nick.

I second that. It's a great scope, I've also spent many a happy hour using it to split doubles and it is amazing on the moon and planets.

Yes really relieved John as I thought the eyepiece was damaged in some way. Now I can really enjoy using it. Tonight this was the only eyepiece I used in the 12" dob and just enjoyed cruising around the sky.

first case contains only 1.25" eyepieces and the second 2" eyepieces. The 1.25" get a lot more scope time than the 2". When I bought the 21 Ethos I thought that would get more use in the 12" Dob  but it hasn't turned out that way, I prefer my 38 Panaview instead both in the 12" Dob and 120ED. The Ethos shows comet like stars in both scopes. I bought the Ethos second hand and it was pointed out to me by the seller that there was a little dent in the body of the eyepiece. I bought the eyepiece anyway as it was a good price. I'm thinking of sending it to Televue to see if they can do anything.

It was a clear night tonight and despite a full Moon I rolled out the 12" dob to try the ethos 21 once again. I put the ethos in the focuser and tightened the 2 screws to secure it and then checked to make sure it was tight in the focuser by giving it a little twist. To my surprise the upper body of the ethos just spun round and felt loose. I took the eyepiece out of the focuser and tightened it. With the ethos back in the focuser I was delighted to see that the comet like stars were gone and showed as round dots from the centre right to the edge.

Really interested in this as I want to get back into Binoviewing. Sold my WO binoviewer and regretted selling it but the Maxbright II seems to be better so maybe it wasn't such a bad idea selling my WO Binoviewer.

Interesting looking finder and much neater looking than my Telrad, how did you attach it to your Tak?

The WO finder bracked is fixed with just one screw into one of the two holes that are used for mounting the Tak bracket.

I use a William Optics Multi Reticule Finder, it's nice and compact and you can vary the brightness.

Are you using a coma corrector in the 12" Dob?  You may be seeing the coma inherent in a fast mirror if not.

Can you refocus for the edge to a sharp focus in the 120ED to account for its inherent field curvature?  I use a TSFLAT2 field flattener in my 72ED to get nice pinpoint stars from edge to edge.

Hi Louis, I am not using a coma corrector in the 12" Dob. I was just a little surprised to see coma with the 21 ethos especially as I don't see it when using my other TV eyepieces. I will have another try when seeing permits, at the moment theres nothing  but rain and clouds for the next few days.

This is a sketch I did in 2015

This is the latest and hopefully the last iteration. 

I have sold a few items but regret selling my ZS71 ed and an OMC 140 which I bought from @Stu. I did put some other items up for sale including my 120 ED but withdrew them from sale as I felt I would regret it. I won't be putting anymore items for sale and will only buy items after careful consideration and not on impulse.

Celestron C6 XLT OTA and 0.63 reducer.

Arrived today, Ethos 21.  Thanks Gavin. 

Looking forward to taking some pics with my smart phone.

This seems to be guide with pictures and descriptions, the other one is a proper Atlas with stars and galaxies and stuff (missing some Sharpless ?

interesting,

Thats exactly what it is.

Very interesting! I like the two sketches of the crescent. It looks like one was with a 14 inch scope and one with a 27 inch scope - is that right? Does it say what skies the sketches were made at?

What is the key difference between the atlas and the guide?

 Just had a quick look, yes one is with a 14" at 200x with OII filter and the other with a 27" at 172x with OII filter. They say all the sketches were made under moderately dark skies.

The Deep sky guide consists of photos and sketches of deep sky objects and the page numbers correspond to the page numbers in the Deep sky atlas.

I have not had a chance to look at it properly yet , I just took a few random pics with a smart phone. I will have a proper read over the next few days.

Avtar, if I had a pound for each time someone says that, I could buy  number of decent eye pieces.
 

Me too ?

Arrived today ' Interstellarum Deep Sky Guide ' I already have the ' Intstellarum Deep Sky Atlas' both are the desk edition.
