For some it ends the first time they fall off of a 9-foot ladder in the dark.

For others, it ends when they start imaging.

For still others, it ends when the scope will not fit in the house, shed or garage.

For some, though, it never ends.

When does aperture fever end? 15"? 22"? 30"? Empty bank account? Grave? Never?


....I also think a lot of us use the "Two O'clock Rule" when considering a bigger scope. Anyone can set up a bigger scope at 8 PM -- but it's how you feel when you have to pack it up at 2 AM that often dictates how you feel about that scope. .....

Why pack it up at 2am? Why not wait till sunrise and pack it up in the light? .....Safety first.


I agree with that one! In the 10 years I’ve owned a 20-inch Dob I’ve only taken it apart twice in the dark, both while at Cherry Springs park in PA. One time it clouded up around 2 AM and the weather radio said it would snow by dawn (which it did). I did drop the frosted up UTA, but it was unhurt.

The other time, on the 4th night of observing and sometime after 2 AM, cloud blew in and it started raining. Two friends and I (brain dead from 3.8 nights of observing) somehow got the 20 and my 5-inch APO in the back of my Tahoe…. only a little wet. We went into my friend’s RV to go to bed, but I wanted something in my truck, and came out to find a dark sky full of stars. We should have just covered the scopes for 20 minutes.

At home I leave my scopes set up for several days at a time, and always take them down in the morning, usually after breakfast. I've also left the 20 set up at a friend's house, and gone back the next day to get it.

It's why I like the 10". It tears down as quickly as it goes up, even in the dark.

That's another thing that I like about my LightBridge 16, it goes together and comes apart quickly and easily. I keep it outside in a small vertical garden shed under my patio cover. I can have it set up and running in just a few minutes and put away just as quickly. Very nice.

I need to do a little video showing how quickly I can roll out my 18" from the Honda Element and setup (and yes, tear down). It's a thing of beauty.

My 17.5" goes from fully disassembled in the house charging to fully assembled outside and collimated in 9min. Dissassembly and return inside in about 3min. (timed it once based on posts on CN)

The Mayans say it (and everything else) will end 21 December, 2012. You have 33 days from today.

So what you are saying is that it's okay to max-out our credit cards as long as we use overnight shipping. Cool. To maximize the time we have left we should also consider having everything shipped directly to our favorite dark sky observing site, that is of course after calling in sick for the next 4 weeks. :)

for me it ended when I bought a 6" AP that blew away just about any reflector I have ever looked through :lol:

Have you looked through a reflector with a zambuto mirror? :lol:

Given that a 0.5 arc-second double is well beyond the capabilities of a 6 inch scope, it won't be blowing away a certain "$240 on Astromart 10 inch GSO dob" when it comes to resolving close doubles.

Yes, we use that blowing to cool down our mirrors, and that 6" AP as a finderscope....... :lol:

For me aperture fever ends with practicality. I find that I prefer grab and go astronomy. I like to get out and view for a few hours, and then pack it up and go to bed. This way I can get out more often. Unfortunately the views from my yard are horrible, but I can get to mag 5.0 or 5.5 skies with only a 10 minute drive. So portability and ease of set up is the deciding factor. Right now the most convenient large setup for me is my 150F5 Newt on an AZ4. Now I know many of you will say that your larger scope will fit in your car, but here is my other catch. I take my scope to the cottage on weekends where I have mag 6.5to 7.0 skies. I Travel with my wife and son in the car so the 150 scope is the largest that can come along for now. Hmmm…. A C8 could also work…ok, ok perhaps aperture fever will end at 8 inches :grin:

In short, what I lose in aperture, I make up with dark skies.

Eric

When you get old and fat, your thyroid goes to pot and that couch looks alot warmer and cozier than standing in the 25-degree front yard.

I view with my friend's 48" scope once or twice a year for a week. Otherwise I use my 22" the most. Setup time is 10 minutes, including the table, etc.
Here scroll to bottom for the 48". :)

My 30" takes two people and 15-20 minutes, which is why I don't use it much. I'm working on a fast 28" scope that will be a one peron and 10 minute setup. That scope ill have a Kennedy mirror and a hybrid design of obsession UC and Albert Highe round mirror box.

Yeap... My 22" smoked my previously owned 8" triplet from TEC. Not even close. Another case was a gentleman who owned an AP180EDT looked through a 14.5" Starmaster with Zambuto glass. He was blown away. Both scopes were at over 1000x...looking at Jupiter and Saturn Not even close....

For me it'll end where the backaches begin, when setup and teardown gets to be a real PITA. :lol:

I'll probably never own a telescope bigger than 12" and more likely my maximum aperture will top out at about 8-10". One consideration that sets this limit for me is that if I get a Dob, it'll be a solid tube version....

I believe that aperture fever ends exactly when you sell your bigger instrument and then search again for better ergonomics, better transportability, better cooling time, better optics, better wife and bank counselor acceptance factor ... however a delivery of a 12.5" Zambuto is expected second quarter next year !

I certainly have been and am a victim of aperture fever. My fever is always fueled when I hear that objects like Hoag's ring and the components of Einstein's cross have been seen in Jimi's 48".

From the practical side, for a dark sky portable scope ( car, van, trailer), most people stop around 30". A very small number of people port a 40" range scope, but it certainly can be done, and I suspect with very careful planning, transport and set up can be done ergonomically. I am not aware of anyone porting a 50-60" scope around.

On a permanent observatory site with excellent skies, other than cost, the next major barrier for an amateur will be obtaining the mirror. I believe Mike Lockwood can make upto a 60" mirror. One could get an even larger mirror from LOMO or other source. I suppose theoretically the fever should end at 8 meters, as larger monolithic mirrors are not made, but then again, who wouldn't kill to look through the 30 meter telescope once its built if it were possible?

Hopefully we will get to hear some viewing reports from the 70" when it comes online.

My fever will end when my 16" zambuto arrives.
