Mount Upgrade
« on: December 27, 2017, 10:04:52 AM »
Hi Everyone,

I've been considering a mount upgrade for some time now to use for DSO AP.  I'd finally decided to go with an Avalon Linear mount.  It's in the very top of my budget and could price #4000 (approx.  $5000) in the UK.

One of the essential things I initially liked about the mount is it's reported slow and smooth periodic mistake, which from what I know is easy to steer out for extended exposures.

However I have recently acquired an ASI1600mm cooled CMOS camera, so that I can do shorter exposure AP, state 30 to 120s.

So my question is would it be worth me considering cheaper choices as I am unlikely to require 20-30 minute exposures.  Or is a slow and smooth PE still desired even for shorter exposures?

Regards,
Andy.

A higher-quality mount will always make your life easier.

Tracking accuracy is only one data point. There is also rigidity, especially during wind. And periodic error smoothness and integral PEC features. Not to mention overall reliability and many more details.

I hope this helps.

I agree with the first poster. You can't beat a good mount. And, you are going to find that most of the time you will be going longer than 30 seconds with the 1600, more like 3 to 5 minutes.

I can attest to to the superb guidability of the Avalon belt/pulley driven mounts. But this is a really good question, and with the advent of at least the possibility of shorter exposures for DSO imaging with the newer sensors, will it lessen the drive for premium mounts? What OTA (s) are you planning to use and what type of objects are you most interested in?

I'll be using the Esprit 100 that I've recently ordered and an ST80 guide scope. With the camera, wheel, rings, bars etc its about 13kg in weight I think.

So I'm going to need an upgrade from my HEQ5 pro. To be honest I've really struggled with guiding my mount despite a full service and belt mod, tweaking of balance etc. I get sudden jumps in PE and my RMS in PHD is almost always well over 1" .

I'm interested in globs, nebulae and larger galaxies with both Narrowband and LRGB.

Regards,
Andrew.

Well, if you hate your mount, you hate your mount.

However, the real issue is whether there are financial tradeoffs involved for you.

For example, I'm facing a similar consideration. In addition to a (better) mount I also need CCD or CMOS camera + filters (LRGB/Narrowband) + EFW + OAG + Lodestar + auto focuser + Moonlite or FT for my SCT + other things I forget...

The question is, will all those (which put together cost as much a a premium mount) improve my acquisition/range of available imaging opportunities more than will improving my mount? For example, shooting narrowband will let me image from home--something currently a pain with my light pollution + DSLR.

If you can afford everything you wish, definitely get the mount. If not, then figure out whether a different allocation of funds might address your priorities better for now.

Many books an astrophotography, usually on page one, say something like "start out by getting the best mount you can afford..."

Agree 100% with Chris and just about every AstroPhotography Book out there... Invest in the BEST mount you can afford. Everything else will work for now and/or be upgraded later.
You get what you pay for. And in the world of mounts, that means the lesser expensive mounts come with horrible PE, Cast Aluminum, Low Quality Bearings (making it difficult to balance), etc. while the top shelf mounts exude quality in their build and more importantly, their performance.

A good mount makes every aspect of imaging easier and more productive, regardless if you want to take 20 minute subs or 2 minute subs.

Actually if you want to do narrowband, you need a good mount. 2 minutes won't cut it. In my experience you really want to do 20 minute subs unless your OTA is very fast (Hyperstar, RH200, or Epsilon). 20 minutes is no fun with a non-premium mount. Not saying it's not doable, just a hassle.

After some further consideration and research I finally ordered the Avalon Linear mount. Should get it in a couple of weeks.

Please let us know how it works out. There's relatively little information about this mount, and it seems like a potential competitor to the MyT and Mach1 GTO at a somewhat lower price point.

Andy,

Before I went with SB / Paramount, I almost pulled the pin on an Avalon Linear.
For me it came down to readily available parts, service and support from a manufacturer in N. America.

Seeing as how you are UK based, Italy is reasonably close in the event you have technical issues.
I'm sure you are going to like that Avalon. Typical Italian craftsmanship.

You're going to love that mount. Very smooth curves on it; easy to guide. Superb workmanship. And, you can talk to the head guy if you need to! Nice choice!

Oh, and it's red!

Since i am in the same situation, i can tell some things

- Luciano is supporting customers far beyond his duty
- pec is nonsense with this kind of tec. It is a guide only mount that correct very often (and very well)
- the next jump is called 10micron more than mach1, twice the cost.

i will go to see an m-uno soon, but i am pretty sure that linear is the only choice balancing price/Quality. Competitors are losmandy only, i don't see a real fight

Please drop some lines about your first tests
