Yes it is a hobby, but I haven't had a clear night in weeks. My skies are clearing by 11pm and I'll be out with my scope waiting for this chance. Its going to be another couple of weeks until my next chance. I have skipped a night here and there sometimes for various reasons. No worries. I really enjoy observing the universe and I try to get out evry possoble chance. Im known to wake up at 3am because the sky will clear then. I'm not a slave to astronomy, but it does rule my free time.

Astronomyforfun - don't feel guilty, just enjoy what you have. I know I will never see everything the universe has to offer. My desire being the enjoyment of what I have the pleasure to observe.

Time to setup for the evening, its going to be a late one! Clear skies tonight.

Alpine Valley? Just found it on my map. Looks interesting. It's now on my list. Thanks!
Bill...
You may want to add other interesting areas such as Catena Davy (the Davy Crater Chain), Craters Messier and Messier A, Crater Schiller, Crater Wargentin, the domes of the Marius Hills, Mons Piton, Promontorium Heraclides (the Moon Maiden), Reiner Gamma, Vallis Rheita (the Rheita Valley), and Vallis Schröteri (Schröter's Valley and the Cobra Head Rille) to your list, as well as the already-mentioned Rupes Recta (the Straight Wall).
Many other other notable lunar features are listed at the following URLs:https://www.astrolea...nar/lunar2.htmlhttps://www.astrolea..._II_Targets.pdfhttp://www.skyandtel.../the-lunar-100/

In the last 3 weeks I've had one "killing" my garbage cans and crunching up my bird feeders (NY's Southern Tier), another running around a friend's house in the Adirondacks (Tupper Lake).

Back in June we did have a "bear on the field" alert one nightat the Cherry Springs Star Party (Dark Sky Park in PA), and they are quite frequent visitors - usually around evening dusk. A year or two ago they had two on one side of the field and another on the other side..... at the same time. One fellow observing on a almost deserted field (total solar eclipse time) posted a photo of one trying to get into his tent during the daytime. The PA DEC Rangers shoot above them with shotguns..... and theyrun off. At other times they have shot them with plastic bullets. I don't think they want people with firearms on the observing field - the thought of shooting someone with an unshielded PC or white-light flashlight would be too tempting......

I have read at least one report of a grizzly that got a snoot full of bear spray withdrawing and doing a lot of sneezing and shaking..... and then returning to attack again! Makes me think bear spray is not enough.....

There is nothing stopping businesses from seasonally adjusting their schedules to reflect the changing day length. In my opinion this would be better than a one size fits all "solution" like DST.

I have the Orion XX-14i. IMHO, there is not enough tube ahead of the secondary. Probably the same for the XX-12i. I use a homemade dew shield placed inside the upper tube assembly, and I also use a Kendrick dew strap that wraps around the secondary stalk. Seems to do the job well here in the dewy DC area.

Wow. Poor girl. I can somewhat imagine what she is going through, though I'm sure she is much worse off. I have a clump of floaters in my left eye that's black and pretty large. I regularly have to swirl my eyeballs around to push the clump out of the way, but it's never long 'til it finds its way back to center. It's so dark that I can even it when my eyes are closed. Hopefully she adjusts (as I have) and learns to put it out of her mind. It's all we can do.

You would not believe how many floaters I have, and I am only eighteen. In both eyes. It almost drives me mad to look at the bright daytime sky, there are so many of the black spots and even strands swirling about in my eye fluid, obstructing the view. But amazingly, I have no other visual problems and my vision is otherwise sharp and excellent; I don't need glasses at all, not even for driving. How I got these floaters is a story too long and unbelievable to be told here, so I'll just leave it at chemical exposure, while looking up at the night sky; to what type of chemical, I will probably never know. But what I will share is my method of beating my (likely permanent) condition. When I am engaged in observing, when I first look through my binoculars, I patiently wait three to five seconds before taking a good look, and keep my eyes perfectly still during that short period so that all the floaters can swirl around and then settle to the bottom of my eye fluid, out of view. My vision is then perfectly clear. I can then take a good look at my chosen object, and move my eyeball around the FOV in the slight motions required for averted vision, without interference. Problem solved, just that simple. And no, I will never get medical interference; far better to make the best of what vision I have (which really is pretty good, all things considered) than to lose all to a slip of the scalpel (or laser beam...). And it's not really a problem after all, even though I can almost guarantee you my floaters are as bad any one's here, due to my little discovery, found and verified effective through trial and error, that I shared above for the benefit of all. Simple, but effectual. Please try it, and see if it helps. Remember though that it may take longer (or shorter) for your eye fluid to clear, so be patient and experiment.
I sincerely hope that my story helps both of you (and anyone else who needs it) to get clearer views and contributes to your enhanced enjoyment of future observation. And as for you, Ring Singularity, please don't ever look at the sun again, even for the tiniest fraction of a second. I am not being an alarmist, just stating the grim facts. Every unguarded view costs you a little bit more of your vision. I wouldn't want you or anyone to be deprived of, or hampered in appreciating, our glorious, beautiful, inspiring cosmos above. Or of the sight of anything of beauty. And if your eyes ever hurt due to frustration with floaters, splash nice cold water on your closed eyes a few times. It really helps take away both the eye-ache and the head-ache, clears your head, and lets you start over and try again.

Best wishes and clear, dark skies,
Chemical pollution? Air pollution? The bane of existence near big cities!

This might be another area to focus on, I was just reading about a study in a medical journal about dangerous pesticides showing up in urine from consumption of produce from conventional farming, it seems like we are always dealing with something or other. I grow my own veggies now, organic and pesticide-free (sorry beyond the scope of this topic, but you mentioned something about chemicals.) In the study they mentioned that 5 days of produce made from organic farming removed the pesticides showing up in urine (the pesticides have been linked to brain damage and hyperactivity- they are malathion and chlorpyrifos.)
Here on Long Island, we've detected these pesticides in our tap water so now I filter everything.

Pepper spray isn't legal everywhere.

Just cause cops can be acquitted for shooting people don't assume a civilian, under the same circumstances, will to.

For the curious, here is how I ended up stacking the two scopes. The upper dovetail is from Astronautics, intended for their GSO 6". As I expected, the holes and screws matched, so adding the upper rail was trivial. I used the two ADM saddles screwed back to back for a double sided dovetail clamp. Have been able to use the solar scope once (else too cold, windy or cloudy...grrr). No chance to use the VRC6 *see previous excuse). Did multi-axis balance, seems ok, more stable than side by side.

Curious about others experience of screws walking out due to freeze/thaw cycles.

The Sterllarvue is a beautiful scope. I'd like to get one myself. It's a lot more $ than the Sky-Watcher 100ED Apo. Especially when you consider you have to add a diagonal & finderscope which the Sky-Watcher comes with. It does sound like a precision made instrument though.

Reflectors Telescopes Forum / Re: focal length measurement question
« on: January 31, 2018, 03:58:41 AM »
Ed, it seems the OP didn't want to measure to the actual mirror, but measure along the outside of the scope to determine the focal length,
but without removing the mirror cell to see how far inside the scope the surface of the mirror lies.
Your method would still require a measurement to the actual mirror surface itself.
I suggested a plumb bob in my post #6 to determine that.
I think it would be possible to get within a couple millimeters.

I"m sorry to say it but I"m back with the same problem!
Everything seemed to be working, I took it outside, connected it and the scope did not respond. Spent the last few hours checking everything and redoing all the settings, everything seems to be ok as far as the computer and ports go. The only real change is that the program when turned on does not remember any telescopes at all. I must configure each and every time.

One other thing is that I do not get a target circle (red), just a white one.

At a Loss Once Again,

Scott

Well I dug my hole even deeper!
I uninstalled Stellarium and reinstalled it and now I do not even have a "Telescope control" button on the bottom tool bar at all!
Can't beleive it. HELP!!!!!!

Keep on doing what I normally do, hope for dark skies and the best weather on a new moon weekend around the new moon in December.

Right now I'm working on open clusters, a few planetaries and the Skiff & Luginbuhl catalog (from the back of their book)since most of the Herschels are behind the sun, or come up way too late for me to tackle right now.

All this means I also have to reprogram the special objects in my Sky Commander to replace the ones I found last month during the dark moon weekend on November 18th.

Now, if the weather breaks...

Mounts Questions & Expirience / Re: Moving your mount around
« on: January 30, 2018, 11:29:27 PM »
Hi Arie,
I built my tripod dolly. When I get home I'll see if I can snap a photo. It's not hard to do, but all the designs I saw were triangular... The door I need to go through is 34" and my CGE tripod legs sit 36" apart. Triangle won't work, but a simple "T" will... And the long leg of the "T" holds the leg of the tripod you want facing North, so that's pretty handy. I can angle the whole rig through the door. I used big 5 1/2 solid rubber wheels from the big-box home depot store. They are rated at like 350lbs each, overkill, but I didn't want to be stuck with the little bitty wheels.

I did see a solution on You-Tube awhile back where a fellow fabricated brackets that attached to each leg of the tripod using "U" bolts. Pretty clever. He had a way where it only took a few mins to "drop" each leg assembly so the tripod would sit in it's natural state. I'll see if that is still in my You Tube history. His idea is probably close to what you want, but he had access to a machine shop (you could tell in the video) and was able to fabricate (cut, bend, twist and drill) 1/4" steel plate to make custom brackets... Bit out of my league.

Good luck,
Mr. Joey

Without going into a technical discussion collimation is the process of aligning the primary and secondary mirrors so that you get the best image. If your scope is out of collimation you will not get the best, sharpest images. The good news is that your scope is not as demanding on having perfect collimation because of the slower focal ratio of f8. If you had a f5 or f4 scope the collimation would be more demanding

The first part of collimation is to align and adjust the tilt and angle of the secondary mirror ( smaller mirror that you see by the focuser) so that it is in the center of the the focuser as you look down,and looks like an circle ( and not an oval) then after you align the secondary you need to align the primary to the secondary. All of this is explained in great detail in the link I provided you in an earlier post

As for alignment of the finderscope first get a terrestrial object that is far away like a tower or light pole, ect that is at least a few hundred feet away in the Telescope using your 20mm eyepiece. Now that you have the object centered in the eyepiece use the screws on the finderscope so that as you look through the finderscope it is moving the finderscope so that the cross hairs are now in the middle of the object you have in the eyepiece. Make sure that the scope didn't move while you were adjusting the finderscope. Readjust if necessary

As for clouds, sorry I can't help with that. That is why we have this site Cloudy Nights!

I'm going to give the contact cement a go. I have the good stuff. I will rough up and clean the surfaces ahead of time. Thank you, all.
