celestron finder-scope, polar part number: 94221

[Paulus]

Hi Everyone,

I am new to this site and have recently purchases a second hand 8" Helios Newtonian Reflector (F/5) on a EQ5 mount. This is a major upgrade from the 5" I had before. Everything is working well optically, but I have tried to get a polar-finder scope for the mount with no success.

I have found out from reading some of the questions about polar alignment that the tube that is missing from my scope is the same as a Celestron 94221 that is now discontinued I found one on the net in the USA but the company won't ship outside the US.

Does anyone know where I might get one from, or even have one to sell? I hope this is posted in the right place and apologies if it's not.

Regards,

Paul

Welcome to SGL Paul . This polarscope will fit: Skywatcher - Skywatcher Polarscope for EQ3-2 & EQ5 .

Hi Tony,

I've tried both these, the EQ5 mount one has the same thread as the one I have the date ring and 3 adjusting screws, but the main tube is .125mm too wide. the EQ3's tube is narrow enough but it is a push fit and is not compatible with my mount! If it helps I could take a photo of what I've got?

Many thanks,

Paul

You can do, I won't be able to help you someone else might do. My only thought is that the mount is an older version and like you say, a slightly different model of polarscope is required.

FWIW, if you're only doing visual observations having a polarscope isn't absolutely essential. I use a CG5 mount for observing and it hasn't got a polarscope. All I do is get Polaris lined up in the middle of the hole where the polarscope should be and that is good enough for me.

Hi Tony & anyone else who is browsing,

Here are 3 photos of the part of the polar mount I have, one on the EQ5, the EQ5 with ring removed & the side view of the ring it's self. Any help will be greatly appreciated. [ATTACH]24194[/ATTACH]

I realise that I can view things fairly easily by eye without being exactly polar aligned, but I am hoping to take photos & would like to get a better camera rather than a new EQ5 mount!

Wonders will never cease, I do believe I've found the celestron 94221 polar scope, after a few hours of googling various word groupings! So all being well this problem will be solved in a few days when it arrives.

Thanks for a great site, with so much information to absorb. I just wish I had more time to browse, mind you the weather in North West Wales has not been conducive to star gazing

Regards,

Paul
