However, coming from southern California trees were unique and rather special to them!!


One doesn't have to be from southern California to make trees unique and rather special to a person.

I personally know how long it takes to grow trees, as I planted one-footer evergreens, and trust me; it's many years for them to achieve any growth.  If trees are healthy, it's a shame to destroy them.  I saw hundreds in my area destroyed by the pine bark beetle; that area will never regrow in most of our lifetimes.

wait a minute,  are you saying the 500mm f4 (non-UC ?) costs 5690euro without an optic but the 5000mm f3.3 UC without optic costs 11890euro??

I recently decided to go for it and purchased a Celestron AVX GEM mount as I had gotten about as much as I could out of using Alt-AZ mounts and short exposures. Unfortunately my preferred viewing location on my property has a limited view from North to South East and the view to the West is completely blocked by trees. When using calibration stars on the same side of the meridian as the stars I selected for alignment the GoTo seems to be fairly accurate but I still cannot get shots longer than 20 seconds if I'm lucky. The other night I could actually just about make out Arcturus through the trees and tried using that as a calibration start but I was way off and couldn't get a decent exposure longer than 5 seconds.

Any suggestions on how I can get a better polar alignment or what to do about calibrations stars? I am going to try setting up in my driveway weather permitting as I have a clearer view to the West there the only problem being I'm then surrounded by street lamps on both corners of my lot.

I attached an image of M31 taken with the new mount, 29 20 second exposures at 1600 ISO using an unmodified Canon 1000D and an Orion ED80 refractor for a 9 minute 40 second exposure. Still working on the processing skills. :-)

Thanks!

Thanks Steve.
I also just noticed when looking at the last test photo, that It is under corrected on all portions of the outer 70%, or so... and maybe a bit over corrected right around the 60-70% zone. I sat in front of this tester for too long yesterday. I did not even notice that when I "finished"

We were in Hawaii in 8/2016 (you can check out the pictures here..https://www.cloudyni...79-hawaii-2016/ )

As to food, the Waikoloa village is WAY overpriced. The cheapest supermarket is in nearby Waikola (around a 5-10 minute drive). The Queens Plaza in Waikoloa has a supermarket but its expensive, still we used it for wine and breakfast. We stayed at the Hilton Kings Land which was VERY VERY nice. I would move to Hawaii if I could its that great.

Hello
Im sure you get a lot of these type of posts but, I just started getting into astronomy, after getting a Celestron sky master 15x70. Ive had it for over a year, and would really like to take the next step in getting a telescope. I have only had the chance to use a 70mm Celstron refactor a friend had once. Ive been researching for a while on what to get, and have two ideas but wanted to get some feed back first. I cant decide between what would be the better choice between a dobsonian, like the 10 inch Lightbridge(which has less weight of the two), or something like the Meade LX70 Reflector, 8" . I certainly would be open to other lower cost options that, but 700$ seems about my price limit.
I would like the telescope i decide on, to be portable enough to put in my car, and travel somewhere, and carry it a reasonable distance. I also am intimidated spending 400-700 dollars on a telescope, when i have almost zero experience using them.
Any advice?
Also Im interested in learning more about whats in the sky currently. Any recommendations on learning the night sky?

There have been loads of good advice for you and you'd be well to take it all and digest it.

Here's mine.

1. You have some good binoculars......USE THEM to learn the night sky. A good book such as "Turn Left At Orion" and "Nightwatch" will help you.

2. Get and LEARN how to use a planesphere, they aren't that expensive, some cost less that $10.00. There are even places on the Internet where you can make your own.

3. Get a DIM red flashlight in order to use both above, the best are ones with a dimmer dial.

4. If you have a smartphone, download a planetarium app., you might have to shell out a few $ for a good one. Make sure that it has a NIGHT mode (meaning in red) to preserve your night vision. Smartphones have blue light which can affect your night vision. If you have a computer or laptop, there are a bunch of these for sale or free on the Internet, one is Stellarium and it is also available in a version for smartphones but that one costs about $3.00 or so.

5. Find out if there's an astronomy club nearby. The one near me has a monthly public night where they have shows or workshops monthly and if the skies are good, several telescopes will be out for people to look through and ask questions.

6. Don't jump into your telescope buying opportunity just yet, do the above first and save your money while you learn the night sky and more about what you really want out of it. This is so you won't be disappointed in your rash purchase wishing you'd spent money on something else or not at all.

I would suggest starting with a 70-80mm,
the best quality that you can REASONABLY afford
and keep as Grab and Go
or may as a finder scope on a large dob,
when you go larger in future

Beginners Forum / Re: deep sky scope upgrade
« on: January 31, 2018, 11:09:54 AM »
I have a 8" f/5 Newtonian, and I've yet to observe with it. If I decided to upgrade in future, a 12.5" would be my next step, although the even darker skies do tend to cry out for as much aperture as possible.

Discovery makes Dobsonians of a quality midway between those that are mass-produced and the premium makers, although the mirrors themselves have been described as near-premium to premium even, and in apertures from 8" to 17.5"...

https://www.optcorp....nian-telescopes

If Discovery is still making them, they're worth a look, and it may be prudent to order from OPT rather than directly from Discovery, from what I've read.

When you get to really small eye relief you will find out how many floaters you have in your eyes. About 1mm is the smallest I will go.

Reflectors Telescopes Forum / Re: Dob Magnets?
« on: January 31, 2018, 05:26:55 AM »
Thanks for all your help.

The 2lb one at Amazon might do the trick. Right now when I use a BV on my 10" Dob I wrap a 2.5"lb ankle weight at the bottom, but it sometimes slips and not a good solution. Being able to move the magnet around sounds a lot better.

Mounts Questions & Expirience / Re: Classic Meade LDX-600 Mount problems
« on: January 30, 2018, 01:39:57 PM »
Hey Francois it was a shot... LOL.

Seriously though I doubt that mount is junk at all, it will just take time to address whether it's a simple problem or not. It is likely someone out there has stashed away the firmware files for the mount and just has to dig through 20 years of computer files to find it if that's the issue! 
As Uncle Rod said, it could also be a failed motor or something similar, more expensive to address for sure, just lucky you have all that other equipment, plus the OTA to have fun with while the LXD600 can languish. It's possible you might find someone at one of the regional star parties that has a similar drive too. It never ceases to amaze me how many lurking amateurs are out there.
Clear Skies!

I guess that's a "no"? lol


I can put you in contact for someone to cut his pattern, you'd have to put it together and clearcoat it.

...here are Zeiss Huygens 25mm and 16mm back lenses, which looks impressive vs Zeiss Monocentric and Ortho back lenses....

Denis,

How is the eyerelief for the 16mm and 25mm Zeiss Huygens? Does it feel supertight or is it OK?

Thanks,
Mark

The 5" Maksutov would probably fit onto the mount, but only if the mount has a Vixen-style dovetail-base, like this... http://www.telescope...vetailmount.gif
