    With a 16" scope you might want to get the biggest of the small scopes - that would be for me a 4" Refractor on an AZ mount. You haven't given us a budget so I am going to point you to something like a 4" ED scope like the Skywatcher brand. I have two sets of scopes, my ST80/2" focuser & Old USA made C90 on my little SLT mount for quick looks and my 8" SCT/ES APO 4" as a "set". I can say this that the 4" is great for things that are not so great in the 8" and the 8" is great for things the 4" is not.

    Yours is what I could call a special case in that for visual a 16" is a beast and your are used to views in it. That is why I am suggesting a 4" ED scope. ED & APO do have kind of a "magical" view to them when it comes to "Lucy in the Sky with Diamonds" kind of views. A 4" ED scope on an Alt/AZ mount is a "grab and go" setup (and I'm 69) for most folks. APO (which are triplets) can be heavy (>10 lbs) - and some folks can't see the different between an ED or APO for visual. I have to say that for things I never really looked at like open clusters in my C8 my 4" APO has given me new interest, something like the 7 sisters are just magical in it. Good luck with your choice'

    Would there really be a great deal of difference between 3.5" and 4". I have found a 90mm / 1000mm gso refractor on ebay close to where I live on a eq mount. Anyone heard of this scope and at f11 the aberration should be minimal. Gso optics should be good I presume.

    Great quote btw Abb. Agree wholeheartedly.

    The difference would be ~30% in light gathering, noticeable but not mind blowing. If you can get a good 90mm for a good price - go for it.

    It comes with a rarely-encountered EQ-4; which, theoretically, should be a bit zippier than an EQ-3, I'm guessing. The refractor itself could be identical to that of Orion's, of California...

    ...but that kit comes with a less-sturdy EQ-2 mount.

    So I’ll give you the minority oponion .... one scope, that’s it
    I know I’ll never own more than one because I don’t have the opportunity to observe often enough that more than one scope makes sense.

    How much observing do you do or plan to do?

    Personally I bought the biggest aperture GOTO I could handle, a few top quality TV EPs and that’s it. When conditions are such that over serving will be favorable I want the biggest aperture possible to maximize viewing.

    The ‘grab & go’ concept I hear about all the time simply doen’t apply for me but by looking at most signatures I’m in the definite minority.

    Having said that I recently joined the secret society of ‘night vision’ astronomers which enables me to do a lot of ‘other things’ with my 14” DOB and it definitely takes the place of having other scopes .... not a cheap alternative but for me a definite winner as I can now setup in my driveway, in an orange zone & see things like barnard’s loop, the veil nebula, NA nebula, etc even though I can’t see the MW naked eye from my yard. And best of all, its real time viewing looking through the telescope just like with any other EP.

    I never stress out about trying to get to a dark site to see cool stuff any more - it’s available from my light polluted front yard ....

    I could dream of multiple scopes, however for now I will have to live with what I can afford ... an 8" Newtonian on a goto equatorial mount with guiding. It's a good all-rounder for both DSO's and planetary. Maybe one day I could end up with a 12" reflector and a couple of refractors, but that's just a dream right now

    Hi Fleegal!

    I own a 90/1000mm 'frac (Celestron Astromaster 90EQ) and the views are pretty good the few times I've looked through it. Here is my last report with it:

    Observing Session - the Moon and Mars (8-20-18)

    The CG3 EQ mount is adequate for this scope, but the Dec axis has frozen up and wouldn't budge shortly after I started using it. So when I need to move the scope in an up-and-down motion, I have to move the scope with my hands.

    Was in Victoria the first two weeks of July - cloudy evenings the full two weeks I was there, except for a break in the clouds on a couple of nights. So I managed a couple of short 70 minutes sessions my time there. Here are the reports:

    Melbourne V Brief Observing Session (7-6-18)

    Melbourne VII Observing Session II

    LMK if questions, thanks!
