ATM, Optics and DIY Forum / Re: Please help me select pitch
« on: February 09, 2018, 08:51:54 AM »
I've experienced the difficulties in working with old used pitch laps, now on an 8/F8.
The 12 year old pitch was much too hard, and left circular channels in the mirror. Then to soften , I added too much turpentine and much too sticky/soft. Then blended old Gugoltz and found what I think is the proper combination of hardness from too soft to too hard.  Without a hardness tester, I use a simple fingernail imprint as per Mel Bartel.
As a young man I put myself through college working on industrial roofs in the auto industry in Detroit and I would come home sunburned with
"pitch sunburns" from fumes as the pitch cartons melted in large vats to be pumped to the roofs and transported at 400 degrees in 5 gallon buckets held at arms length walking to the job site.
For those in the know, the place in Michigan I would pick up the Pitch, was a place called Zug Island.
Dobson would say he found the pitch/tar for his polishing from street repair trucks, but I wonder if it was true pitch, or road tar.
So blending actual pitch, or tar, or beeswax, etc is a highly difficult task in order to obtain the properties needed.
Wish there were a better way.

Any of this dread about the overcrowded eclipse experience reminds me of the 1991 total solar eclipse in Baja, Mexico, which had a profound effect on my life since then.  I made the mistake of listening to some people in my astronomy club who described how miserable the travel experience was going to be, and chose not to see a 7-minute eclipse.  Of course, the report from those who returned was that the experience was anything but miserable.  The life lesson for me was to take minor (and sometimes major) risks when traveling.  It's amazing how much more fun you have when you shed the unnecessary anxiety.

Beginners Forum / Re: How do you organize your eyepieces, barlows, etc?
« on: February 09, 2018, 03:21:36 AM »


I keep my eyepieces, filters, Barlow's a case that's organized by focal length. My other accessories I keep separate cases/bags.

At night I often work out of the case, opening and closing the lid every time I change eyepieces, it help eliminate sewing.


Tablet + Spell Checker : Dewing => Sewing..  Keeping the eyepieces in the case with the lid closed helps keep them from dewing up.

Dang spell checkers! Okay, if I type in a Hawaiian place name like Koloa or Kapaa, that's one thing, but mine insists that I misspell Los Angeles. I'm from Los Angeles and I know darn good and well how to spell Los Angeles.

I generally just ignore it.[/quote]
Just learned a few minutes ago from talking about the cloudynights NCAA Tournament bracket that my spellchecker is apparently not a Villanova fan either.

If anybody here wants to start a bracket, it's easy to do. Just look for the March Madness thread and follow the link.

Well either way it'd accomplish the same goal.

Better perhaps to ensure that the entire surface cools uniformly - then you can forget about thermal distortion.

There've been some modeling threads involving active boundary layer removal in the not too distant past.


This is a grab and go scope for a grab and go situation. In my opinion a GEM is not a good fit for the original poster's needs. A porta mount (or some other alt/az setups)with a F6 refractor is a simple out the door easy to use setup. It has slow motion controls for centering the object.

I'm a huge fan of simple grab and go alt/az setups. GEM's are a pain to setup/get our the door with, but are useful for tracking situations (assuming you have motors on it). Another factor is this scope is unlikely to have a rotating focuser...another plus for an alt/az scenario.

For me GEMs shine for high power planetary work (250x+) and outreach where you don't want to have to re-center the object for people. But for most grab and go situations, an alt/az mount with a small refractor is about as good as it gets.

You got it. I'll keep the scope on the mount and tripod in my garage (I keep it almost as clean as the house) so that we can say, "Hey, there's Jupiter. Let's look." Then I grab it, pop the legs open, point, and look -- making adjustments with the slow motion controls. Simple. I'll go more complicated with a larger scope down the road.
I think you'll be happy with either the Vixen Porta or Twilight I They are both similar and get the job done. BTW the Astro-Tech Voyager 2 is the same as the Twilight I if I'm not mistaken.

I pulled mine out on short notice to catch the crescent of Venus before it dipped below the trees last night. Nothing like a nice grab & go setup.

Find the best deal and enjoy the skies.

Reflectors Telescopes Forum / Re: best scope for urban center observing?
« on: February 08, 2018, 12:25:48 AM »
I am in, right in, the Dallas light dome and I have a floodlit church parking lot just across the alley from my driveway observing location. SQM-L values are always below 17.35. Conditions suck here!

With my XT10i earlier this week I observed M94's bright center and surprisingly good traces of the close halo, M81 as an oval cotton-y patch, NGC2392 as a lightly detailed object with bright center star. M44, 67, 35, 41 and other prominent open clusters were easily seen though with MANY fewer stars than from a dark site. Globs show little detail and resolution but can be seen. M42 and M17 can be seen but are without their extensions. Just the brightest parts show at all and narrowband filters are pretty much necessary. The moon often looks really excellent as do Jupiter and Saturn. Saturn's moons are limited in observability. Large bright galaxies are almost always limited to looking like dim small round cotton patches and that only if they have particularly bright cores. Open clusters and double and/or colored stars are my preferred objects from here.

So I think an XT10i with a flocked tube can make about as good a tool as any for a badly light polluted location.

Better would be an XT6 and a tank of gas.

well I have had my 8 inch gso for some time around 3 years I think and in that time never had to adjust it but was looking at Jupiter yesterday morning and a big bird dropped a great crap on the mirror it was around 4am here in RSA so normally they are sleeping , had to take the mirror out and clean it , but after replacement was 99% spot on , so dont fiddle too much

What are the chances of that happening? Incredible.

I agree, people make way too much out of this collimation thing.

I find them at best to be amusing.

My "Silver Bullet" (The Lone Ranger) is better light pollution filtering.

People, places, and the paranoid, won't shut off their lights.
But if I crank in my HA7nm filter, they can kiss my telescope.

When I first bought my zeq25 I tried to mount my CR150HD on it. The OTA was well within the weight of what they said would be supported, however I found out that nope, the counterweight supplied would only work for up to about 15 pounds, and I found it out the hard way. I do wish they communicated what is supported with what they send a bit better, but a counterweight extension bar would fix your problem.

That is good news. I sometimes notice black spots and short streaks in my vision. This seems to happen when my blood glucose levels get too high for a few days. After I get my diet modified again the spots will be gone after a short time. This is a result of my diabetes.

earlyriser, imo, that language should be inserted so it applies to any greenhouse, not just carnation growers, orchid growers, seedling growers, or some other targetted group like the specific subject of the thread.

As a lawyer, are you saying that the general language would survive (which I think could be true with the growing - albeit slow growing - awareness of light pollution ), or that you could successfully target one group and not the others? If the latter, for curiosity's sake, can you give a general idea of how that would work? (ie, without ending up causing a great expenditure for the citizenry in courtrooms)

edit: ps> Although I would think it would be tacitly known what I mean, to be clear I mean augmented-lighting greenhouses, not tradition sunlight-only greenhouses.

General Astronomy & Observing / Re: Astronomy has me disappointed
« on: January 31, 2018, 07:31:09 AM »
Ever since I saw Hale-Bopp as a young kid, I've been interested in the cosmos and observing what we can. Now that I've settled down after college and doing my part to provide value to society (job), I've became even more interested/involved in this avocation/lifestyle. Not just observing but also learning by reading about the things we observe and the possible explanations of why/things are. However, it has become painfully clear how little humanity cares about the cosmos. In fact, if NASA pointed the powerful Hubble telescope at the earth they still wouldn't be able to locate America's interest in astronomy (I'm exaggerating-work with me). Even my own family feigns interest for a little while for my benefit but they don't stay up late with me at the eyepiece. The more I get involved with astronomy the less I care about social status, politics, and news. I really don't care. Once you truly have perspective, you realize how insignificant humanity, our pursuits, and the earth is. It's all ephemeral and I'm just in awe/disappointed of how certain people are of their place and never significantly wonder about things other than their day to day living. Does anyone else experience feelings like this or am I way off? I'm starting to feel detached from society.

This is interesting.....I agree but you list all of the reasons why I like astronomy.

Lol gitane... spent 5k to learn you only needed to spend $500. That my friend is me in a nutshell.
