Where do people find these things?! It's not fair! DRAT!
Those DS-16 scopes always get cut up and turned into "DOBs". ARRRRGH! Please, keep this one original! Yes, the OTA can be a bit awkward but, it's not something that you see anymore.
Those DS-16 mounts were actually pretty decent. However, they were well challenged by this monster OTA. IF they had been supplied with 2.0" or even 2.5" axles then things may have gone better for them. I can state from personal experience that those mounts handle 6" f/15 refractors with ease. My old man loves those for use on his 6" f/5 Jeagers and other refractors.
If you can handle the weight and all then you will have a really great scope. As long as the optics are good, you're in like Flint! LOL
Good choice by going with Spectrum. They serviced some Cave optics for us recently and we could not be happier.
Now, about that being so darn lucky part....!
You hit on all the right matching words so from the beginning:
People find these things by them popping up. You don't want to know what I paid for the 17.5" red one. Same construction as the DS-16.
No need to cut them up to turn them into dobs. It is a minimally intrusive operation. Just add trunions. The red one is a dob.
The DS16 mounts are actually pretty decent. Yep and same design as the restored RG shown on the right. You mentioned 6" refractors both F15 and F5. The mount shown is handling a 6" F8, right in the middle along with a 60mm piggy. The refractor combination is actually too light for these mounts. I had to find smaller counterweights. The mount still gives a bit heavy feel in use with this light a payload.
The optics are usually good, the OP should be in like Flint (very fun movies, classic).
I haven't tried Spectrum yet.
You still don't want to know about the luck on catching the 17.5".
The GEM under the red tube is capable of handling the red tube...when it gets done (a true dangling participle, Yogi).
