They do go together well.

What would be your opinion on an Explore Scientific 6.5mm 1.25" eps? I wouldn't go any higher than that and at present my highest power is a TV 8mm Plossl.

I have a few ES, although mine are all the old focal lengths. 

 

 

Mine still get used a fair bit.

 

 

I don't know about the newer lengths. There's nothing wrong with any of them though. 

 

 

I'm pretty certain they're JOC. 

 

 

They do well in dew as they're filled with kryptonite or something. Although, for lunar/planetary I tend to prefer less than an 80° AFOV as there's less glass and therefore less concomitant problems. Usually I'll use TMB clones at the most. For rich field/deep sky the ES easily hold their own with any other 'premium' EP's.

The 8.8mm is outstanding and one of, if not the best of, the range (seen above with added Barlow element).

Mine are mostly ES. 3 TV Plossls, a Radian and a set of Pentax XL's. The ES I am thinking about is the cheaper 52 degrees which will be fine for what I want, I just wasn't sure if I would be pushing the mag too far.

I think I briefly owned a bino pair of 52°.

 

 

They seemed fine, although I ended up getting into an argument with Telescope House as one of them showed debris and I had to return it a couple of times. As a consequence I sent them both back and went with WO SWAN's.

I have the Baader planetary set but the lenses are so tiny I don't like them.

As for magnification, it depends on the target, so it's difficult to be objective.

Better eye relief/ergonomics might be a plus. I think comfort while observing is important.

[Scopeman]

I don't like Telescope House, I remember taking my 10" Meade SCT there by car to get it collimated, I had it on my lap all the way there and back, the collimation was worse than when I got it home than it was to start with! Never used them again after that and that was years ago now.

[Nightspore]

Yes, they lost me as a customer years ago after several issues with returned items. I've been thinking, the 6.5mm will give you 237x on the 127mm. Which is only 17x less than the 257x at an 0.5mm exit pupil. So quite do-able for Mars and some other objects. It's probably a good idea to have at least one eyepiece that gives around an 0.5mm exit pupil.

[Scopeman]

Yes, I will get it, last one in stock too.

Is there a safe way to get the blackness back on the Pentax's? They are quite old now and turning grey, don't want the rubber to start perishing.

[Scopeman]

Got a notification that you had replied but there is no reply, have I missed something?

Sounds good. If the weather holds you might get a butcher's hook at the 'Pup' (Sirius B) with the 127mm. It's do-able, although Sirius has to be placed well, usually near transit, and good conditions.

Gremlins?

I usually wipe any rubber turning grey with a microfibre cloth. TV eyeguards can do this over time.

No way to make them black again then

 

[Scopeman]

That's weird, I tried the microfibre cloth and it has wiped off, thank god!

[Nightspore]

Yeah, it works.

[Scopeman]

I also have put on a very thin layer of renaissance wax and polished it straight off and they look like new again. It must be salts from skin, that will stop it.
