Thanks for the replies! I am considering a 5' f/9.5 achromat. I have an 80 mm f/15 that is nice but doesn't show too much detail and isn't very bright on Saturn. Looking at Jupiter through it at around 75-100x I can make out 3-4 cloud bands and the Galilean moons, but the cloud bands run together and it seems kind of blurry, even in the best focus.

- It can be shown that, for a circular aperture of diameter D, the first minimum in the diffraction pattern occurs at θ = 1.22 λ / D θ = 1.22 λ / D (providing the aperture is large compared with the wavelength of light, which is the case for most optical instruments).
Only Aperture 3.6 is fully compatible with MacOS X 10.10.3, so you need to update to version Aperture 3.6. after upgrading to MacOS X 10.10.3.
But Aperture is no longer sold at the Mac App Store, and the Updates page will show 'Currently not available', and we can neither update from the Updates page nor buy the upgrade from the main 'Featured' page of the store.
As a work-around: Reinstall Aperture instead of updating it.
Aperture 3.4.5 Update
If Aperture is associated with your AppleID as you bought it originally from the Mac App Store or you accepted a boxed Retail version to your AppleID when you updated to Aperture 3.4.5 or later, you can reinstall from your Purchases page. In all other cases you need the help of the App Store Support as described in the last paragraph.
- Open the Purchases tab of the AppStore and sign into the Store menu with your AppleID. Is Aperture listed among your Purchases? It may be hidden. Try to unhide it, see this link: http://support.apple.com/en-us/HT4928
- Then proceed as described in Barney-15E's User Tip for iPhoto: (I replaced 'iPhoto' by 'Aperture' in the quote)
Just as a precaution, copy Aperture from your Applications folder onto an external disk or USB stick and eject that drive.
Delete Aperture from your Applications folder. Make sure there are no disks mounted that have a copy of Aperture on them. Empty the Trash.
Make sure no other users have Aperture open in the background. It is best to have all other users logged out.
I ended up having to Restart before I could clear Aperture from the App Store memory (it was still showing Update on the button in Purchases).
Aperture 3.4.5
If it is still showing as Update, try searching Spotlight for Aperture. There may be a copy on a mounted external disk that it is identifying.

You should now be able to go to the Purchases tab and find Aperture with the Update button labeled 'Install'. Click 'Install' and it should download the current version which works with Yosemite.
When I first tried, after authenticating, it posted a 503 error and asked if I wanted to Retry. When I clicked 'Retry,' it started downloading.
It's about 1.01 GB, so it takes a little while to fully download.
2. If your Aperture 3 version does not show at the Mac App Store Purchases page, give the App Store Support a call. There is a 'Support' link in the Quick Links on the main page of the Mac App Store. Ask for a redeem code to be able to download the update. You will probably need to provide a proof of purchase and be very insistent.

Alert: Aperture vanished completely from the Mac App Store and is no longer available for reinstalling since September 26, 2015. This User Tip does currently no longer work. This no longer applies. Apple restored the ability to reinstall oldr pruchases. http://www.macrumors.com/2015/09/29/older-software-returns-mac-app-store/
