Does anyone know what's going on in the ortho market? Clicking on University Optics' website brings up the message: "Thank you for visiting, but this web site has been closed down at the request of its owner."

Going to Agena's website shows that AstroHutech orthos and Kasai Trading Co.'s eyepieces are on closeout - all sales final, no returns accepted.

My understanding is that basically all of these orthos and other Japanese eyepieces are all made in the same factory in Japan. Is it possible that there's something going on at that factory? Are orthos done? Does anyone know what's going on here?

I'm going to be tutoring younger students and mowing the lawn at home to save up for a Zhumell dob in the next few months. I should have enough for a Z8 by mid-April to the beginning of May and a Z10 between May and June.

The question is, for me, which size? I don't care about the wait.

I want to see a lot of DSOs. For planets and doubles, I have my NexStar 4SE. However, with the NexStar all I can see are M31 and M42, along with about 10-25 globular and open clusters. I'm interested in seeing more galaxies and nebulae, though. I live in some dark suburbs, but 4" is just not enough aperture for deep-sky.

My budget is $400 - $600, but I am really worried about moving it. I'm a teen, and I can probably lift at most 35 pounds if I drink some protein shakes. This would mean that for the Z8 I'd have to take it apart to move it, or even get help doing it (not a huge worry, but it means that I wouldn't be able to set up by myself, which would be frustrating this summer). For the Z10, I'd have to buy a dolly for another $100, which I'd much rather spend on a filter or eyepiece, or combine with more savings to get a nice case for my NexStar. The Z12 is out of the question. I doubt my parents would let me buy it, and it weighs 75 pounds.

Things I want to see include the Virgo cluster (along with the Leo I and Leo Trio galaxies), M51, M81, and M82, along with plenty of others I can't name at the moment.


Subject explains it all. This is the graph I am trying to add to my signature:

http://www.cleardark...key.html#appearI tried using this code from that web page:

I can't seem to get the graph to show up, just the code.

Hey Folks,
I"m in the process of selling all my 1.25" gear and upgrading to the 2.0. If I can get away with it, I only want a maximum of three 2" eyepieces for my 8" SCT f10. In your opinions, and in your experiences, which eyepieces would you choose? I'm thinking of the Baader Mark IV, with a wide field low power on one side and a high power piece on the other. Thoughts?
Much appreciation.


Light Pollution Topics / [HELP!] New neighbors & backyard light pollution
« on: December 30, 2017, 02:19:45 PM »
I'm writing this rather quickly to hopefully get an answer to a rather interesting situation that I'm recently stuck in...

Today, after several years of bliss observing from my dark backyard next to a vacant house, the inevitable has happened...the lightless, vacant house I so cherished is (just now) being rented... Originally, I believed that the house would be rented by a rather nice elderly couple that I had the pleasure of meeting a while back. Sadly, the deal didn't go through and the vacant house stayed on the market for another year. So, I was surprised that today a car was driving up to the house. I soon found out that these people would be my new neighborly companions for at least a year or so. I love new people, and try to be as social as possible, but I'd been so used to an empty observing lot that I was rather wary of anyone else moving in to my "light-free zone." The problem is, that out of all of the people that could have moved in, we got (as described by themselves) "the party family." And of course, the dark backyard was the first thing to go. A new ultra-bright porch light was installed, ground lighting was hastily added, and to make things worse, they're literally stringing up white rope light around the shared fence and hot tub area. I still had some semblance of hope that they would at least go to bed at a decent hour... Well, lets just say that I'd hate to see their electric bill. I didn't even know it was possible to turn on every light in the house without blowing a fuse with our development's garbagy electrical system (but you learn new things every day!) Ursa major is invisible to the naked eye now, Andromeda has turned into an extremely dim splotch even through my 8 inch SCT, bright Deneb is hard to find without averted vision, and I need a webcam to take long-exposures of polaris just to polar align! What should I do? Should I try talking to them and tell them that their bright lights make it hard to observe the night sky? Should I put up some sort of "light shielding" in my yard? Should I give up backyard observing altogether? Help!

Hi guys,

i have searched everywhere before posting. or threads are too old or does not explain enough..

i am struggling with my az-eq5.. good for visual but it is showing its weakness while i am moving toward astrophotography..
Since mounts are not cheap at all, i wish to plan steps earlier, just to understand how much money i need.

I wish to be my definitive mount, i am not gonna change again (hopefully). Guided/unguided is the same, i wish only not to struggle anymore for everything. Main ap scope will be a 100/600 apo, 6kg, maximum real weight 20kg is perfectly fine also for my c9.25 (i might mount both at the same time).

Given that i wish not to spend so much for a Mach1GTO or a HPS1000, the area in between the 3k € of celestron/ioptron and the 8k+ € of 10micron/astrophysics seems to be very poor.

the options are:

- Losmandy G11. It has been renewed recently. it has a good accessory that can split the two axis for better weight managing. I dont know how much is better than before. someone love it, someone hate it (btw, it is much more expensive in europe than in the us).

- Avalon Linear: a guided mount. it might show its weakness in visual, but i dont do it so often anymore

- Avalon M-Uno: linear-premium-version. same thoughts

...then? what else? is it over there? i wish not to go chinese again..

Thanks for advice

Mounts Questions & Expirience / Sell me a mount!
« on: December 26, 2017, 06:58:21 PM »
Ok, so not necessarily one of yours, unless you are selling.
What mounts or mount does the discussion appear to like the best for small refractors?
I have got a few 60mms of various focal lengths, searching for something inexpensive but stable to use together.  Bonus if the mount can handle heavier loads.

Beginners Forum / Beginner Question — “Life after Planets?”
« on: December 25, 2017, 09:53:10 AM »
I've had my telescope for around a year and 1/2.  It is a 127mm MAK-Cass SLT 1500mm.  I've had quite decent view of their disposition and planets -- Saturn and Jupiter this summer.  Also was able to take some decent pictures together with my DSLR.  The question I have is this, "What is next?"  I would like to view galaxies and nebulae however, I'm in a really urban environment and there is quite a little light pollution.  I've been trying to find M-31 and M-14 with minimal luck.  Locating them is a trick.  I live in Wisconsin (Milwaukee area to be specific) and have adequate access to the South, Southwest, West, Northeast and Eastern paradise.  Any hints would be greatly appreciated.

Beginners Forum / Ok does the view change when I grow up.....
« on: December 24, 2017, 04:02:27 PM »
Okhere is a little background on my questions-I altered my Tasco 11tr a 114mm reflector(I had posted about changing the range in the ATM, Optics, and Diy forum, kind of a faux pas - in which I was talking about changing my reflector , where someone else was talking about their 34 inch mirror lol) I mounted a 1.25 inch focuser to replace the factory issued .965 inch focuser - that the reasoning was that there's a lot more options in 1.25 inch eyepieces, once I purchased the vintage 11TR scope it came with a publication on telescopes , also using the advice in it I evenmade a couple eyepieces- I made my own plossl eyepiece by taking two binocular eyepieces and taking the doublets from them and putting them back to back , and turned into an adapter to get a microscope eyepiece so I could use this , and yes I could have bought a few high quality eyepieces in the .965 diameter , however I found a bargain on craigslist that provided a range forparts which turned out tohave a few 1.25 inch eyepieces, instead of fight the current I opted to purchase a inexpensive 1.25 inch focuser off of the classifieds.  I mounted the focuser , and also did collimate - just to find that the focus stage had shifted , the new focuser was

So I had to alter my reflector by cutting about 1/2 inch away from the base where the primary mirror here goes my queries

1. My connundrumwasI ran from focuser earlier I could focus together with the newly installed 1.25 inch focuser -In my thinking the focus point was fixed and needs to be complete - cutting off 1/2 inch of this scope means I changed that focus back up the focusing tube - after I cut the 1/2 of this scope , and remounted the push pull primary mirror base , collimated , I really could successfully focus on stars , along with the moon.  I had a comment that said that the image might be dimmer - in spite of the fact that I am now using larger eyepieces - is he/she correct?
If he is correct - please clarify

2.  Should I get a larger scope - will the opinion really change ?  (when I grow up and find a larger range lol) - I assume it's going to be brighter but not larger - say like I use my own Meade 9 millimeter Super Plossl in my Tasco 11tr , then turn around and set it in my newly purchased 12 inch dob , I understand that the opinion in the 12 inch dob - should be so much brighter - will the view be larger or will it be essentially be the same - say for example the field of opinion in the Tasco 114 millimeter reflector lets me view the 3 stars of Orions belt , when I look with the 12 inch dob , will I see the exact same 3 stars or today I can view the 3 stars of Orions belt , along with the"bow" stars ?  If that is accurate - please clarify

Beginners Forum / Stay warm forever, clothing for the winter astronomer.
« on: December 24, 2017, 08:15:46 AM »
Hey guys, I recently got into astronomy and the one thing which kept cutting my sessions short was that the extreme cold we've been facing lately.  Well, intense for a California boy who lives in a desert.

Last week it hovered around 20 degrees all night with a few wind and in that type of weather it is hard to get anything finished.  However, I've discovered a solution.  My folks used to work back to the farm in Minnesota so among the first things they would do before going outside was to throw a pair of insulated coveralls.

Be the envy of your astronomy friends by appearing just like Dr. Venture, and as an additional benefit it is difficult to use the toilet!
Seriously though.  Duluth Trading Company and Dickies equally create these.  You can get them  without.  Links coming down.   Here and Here.
Obviously they don't need to be Dickies or even Duluths however they're well known clothing companies which don't skimp on producing quality outerwear.
I understand you guys back east are seeing unseasonably warm temperatures, but believe me it'll get chilly for you too, and you'll be more happy using a pair on if it will get chilly.  You can literally throw those things on in seconds and I have found these to be exceptionally nice and hot.
Another thing I have discovered, that's enormously better than cutting a fingertip off your gloves are these, here. 
These allow you to utilize your smartphones, which have become an increasingly necessary item with detachable scopes with amateurs, in addition to being a useful reference for individuals with additional experience.  Or a means of controlling your complete telescope as with all the Celestron Evo's.
Incidentally, if you are working a phone at a black sight, you are going to blow up your eyes looking at the display, but many apps today transform your phone into a nightime red light.  Here is one.

Use this thread to talk about the nice and the necessary things you need to do to be able to be observing in those winter months.  Remember never to operate below your telescope, or your electronics', temperature limit.
I would not be afraid to wear you into a celebrity party.   ****, make them freeze!   I have obtained <strong>scienceing</strong> to do!
