Hi guys. Is this a smart idea if one wants to have a dobsonian for both DSO and planets, especially for a beginner  ? For example, the f/7.85 150P Skywatcher dobsonian with a 0.7 reducer will give me  f/5.5.  Will it show less coma (with the reducer) compared with a native f/5.5 dobsonian lets say ? Or  I'm chasing the wind here..lol

The truth is that I'm pretty much a beginner at observing but I like reading up tons of stuff about equipment before buying.  I'm currently using or a pair of Oberwerk 15x70 binoculars  on a tripod, and I'm  thinking about a dobsonian...And a 'slow' dobsonian used with or without reducer looks like a good all-rounder, for planets and DSO

So, good idea ? Or is this a case of ' jack of all trades, but master on none'..lol

Any help and further reading suggestions will be muvh appreciated. Thanks

The neewer trigger ball head on a monopod would do OK if the binoculars are not too heavy, beat used when reclining or lying on the ground so the zenith is easier to view. With mounts it’s always best to get one that is chunkier than it needs to be. The trigger head needs regular ball cleaning and tension adjusting to prevent slippage. P-mounts are not common and historically not cheap.

Guys, what do you think about this cheap tripod ? 

https://www.amazon.co.uk/exec/obidos/ASIN/B01LQX0P8Q/1944

I see the can handle even 5 kg.

This is pretty cheap compared to a p-mount. Any thoughts on it ?

Damn, they're at least as expensive as the binoculars.

I'm gonna stick around in the classifieds sections...maybe something used comes up.

Hi guys,

I recently bought a pair of Oberwerk 15x70 binoculars. Found them used, but in excellent condition. Only 240+ some extra for delivery

Can you suggest a study P-mount for them ?..They are 2.5 kg/ 5.5 lbs

Thanks

What do you mean nothing? Due to Brexit they are having to change shipping company’s , I’d order from Astrograph before 1 March and miss out on the 15% price rise.

 Nothing on the few websites that I know, thats what I mean.

And I haven't heard about that website you're saying. I'm pretty new to this.

Hi guys. Where could I buy the APM 100° 20mm eywpiece in the UK?

I know a few websites, but I checked and nothing. Any suggestions ?

The ED versions are too expensive for me right now. Even the 70mm ED version from the APM are 2000 euros. And although I know they're excellent, I don't want to spend that much.

I want to spend around 1000, bino+ mount. Thats why I was thinking Oberwerk 25x100+mount. I had the 15x70, and I'd like more magnification...especially since I want to get a mount now

So what should I get around £1000 ? another pair of 15x70 with mount ? Why not 25x100, or something in between ?

What avout some 20x80 ? I think there are good p-mounts for this. I read most of them are half the weight of 25x100 .

Your thoughts ?

Well, i forgot to mention that I've used a pair of celestron skymaster 15x70 before, for a while. But nothing serious, nothing methodical. Just moon, orions belt, plaiades and andromeda, occasionally...and nothing else much. I still have them but they're damaged. I had them since 2010...but I've rarely used them all this time.

My thought is that I still need binoculars, not a telescope.  I could still get a lot from a pair of binoculars ..learn the sky better, for example. Expecially if I get some 25x100 on a parallelogram mount. I haven't had any mount for the 15x70, and I should have. I would have used them much more often

What do you think...should I get a 25x 100 on a parallelogram mount, and get a telescope later, if I stick with observing? I see a lot of recommendations for Oberwerk 25x100 IF. Should I get them and see in a while ? They're not that expensive, and I'm not gonna make them redundant soon, even if i get a telescope later. I enjoy observing with both eyes a lot

So what's your thinking...get this binoculars to replace my 15x70, use them yo get better with the basics, and see later about telescope ? If so, what solid P-mo6nt should i get for them ?

Thanks

PS: I started the topic with big AFOV binoculars, but I got carried away...they're too expensive, and I want to keep costs around 1000 for now. I'll see later

I've got a few vintage 10 and 11 degree AFOV 7x35mm binoculars.  Amazing views, but almost negative eye relief.  They used aspheric lensed eyepieces to achieve really decent edge performance.

Why ultrawide binoculars in the first place?  You could try binoviewers on a refractor or even a binoscope as alternatives.

I'd like to take them with me on trips...so basically I want them for nature sighting too....But you got me thinking: maybe I need something for astro only...since whatever I'm gonna get I'm gonna use it for astronomy way more often than nature sighting

I was thinking about a short ED refractor+binoviewer+ wide field eyepieces before, btw...so I'm gonna give this some more thought and come back. Thanks guys

How would you compare the following binoculars... ?Which one has better optics? Which one should I avoid? Any other achromatic binoculars with swapable eyepieces and aperture around 80mm I missed ?
Thanks

Can you recommend me some ultra wide AFOV binoculars ? They can be bulky, or expensive (£ 1000-£1500 let's say ) .The wider the AFOV the better. I would like 80, 90, 90+ degrees... and 15x + magnification if possible. I will use them on trepied

Are there any like that ? Thanks
