Good evening everyone, My name is Naim. I am new to DSSG, this forum, and the state of Mississippi. I have temporarily relocated to Hattiesburg to work with Kohler Engines as a safety engineering co-op. I recently graduated from the University of Florida. I first read through the forums to orient myself to current and past happenings. I'm ecstatic that the star party has moved to White Horse! Currently, I do not own a telescope. (BUT I AM LOOKING!) I possessed a pair of 8 x 50 binoculars, which I returned to a friend's father, before I relocated to Hattiesburg. Those binos served me well on spontaneous trips to the Cedar Key Airport, which produced fairly dark skies and clear skies in winter. I started visiting the Cedar Key Airport after a class trip to Seahorse Key, an island in the Gulf of Mexico, a short distance by boat from Cedar Key. Seahorse key is a wildlife preservation; we were honored to have this trip permitted. I spent a night atop the lighthouse, which was constructed on the highest point of the island and a relief from the clouds of mosquitoes below. Climbing through the hatch, my eyes not dark adjusted, I saw my old-reliable friend, Orion. Soon after, the Pleiades. The wind swirled swiftly strongly and erratic. The sky cleared of the evening cloud cover. I just laid prone and let my eyes adjust. NEVER HAD I NOTICED TAURUS! Orion the Hunter, Taurus the bull, makes sense. Then Cassiopeia. I had never seen the boastful queen. Then Gemini. Seeing so many constellations in one September (or was it October) night, surely you can't be Sirius? I was happy to be in this place, falling in love with the sky. Visiting the Cedar Key Airport was my attempt to get as close to Seahorse key as possible. Since that time, I would visit Cedar Key randomly with binoculars, no star maps, and drive home usually between 2:00 and 4:00 AM. Viewing the vast number of stars would cause me to breakout in laughter and smiles from awe for the first time in my life. From the Labor Day gathering and the official star party, I'm hoping to learn which configuration of telescope I prefer, great sites for viewing in the Southeast, and tips for eventually viewing planetary nebula. I envision myself becoming a proficient visual astronomer before I attempt my goal to resolve M2-9 with astrophotgraphy equipment. I set M2-9 as a goal, because look at it! upload.wikimedia.org/wikipedia/commons/e/e6/The_Twin_Jet_Nebula.jpg It will be years before I attain a satisfactory image, but cheers to setting goals. Naim

Yep, Minkowski's Butterfly. Really cool object, but visually pretty faint and small. At nearly 15th magnitude, that's a large scope object (16" and larger). See observing.skyhound.com/archives/jul/PK_010+18.2.html Like everything else in astronomy (and elsewhere), just work toward it. In the meantime, there's also a lot of other eye candy much easier to see. Hopefully the weather will cooperate and it won't be a sauna or convection oven at night over Labor Day weekend.

Hi Len, I agree.
If the humidity in Hattiesburg is any indication of the humidity in White Horse in two weeks, the horizon will be troublesome. In October, I expect the weather to cool substantially and lower the humidity a touch.
Wow, the size is much smaller than I would have guessed. I knew it was faint at magnitude 15.7, but wow. Having this is a goal means that I will have to keep improving for many years.
What was one of your first visual or imaging goals?

Too far back to remember -- 32 years -- but whether it was good or poor, the first view I had of Saturn in my little scope (and given the so-so quality of that scope at the time it was probably so-so at best) still sticks in my mind. Not so much for how it looked, but that fact I was looking at Saturn directly, not at some photo of it.

Excellent. I hope to learn more from you all this coming labor day weekend. I'm going to attempt to bring a few people with me to the official DSSG in October to do my part to increase attendance if only for this single event.

I've narrowed my telescope search to an Explorer Scientific 127mm Triplet Carbon Fiber Refractor with FCD100 glass.
This is a long term investment, because this refractor will be my only scope for the foreseeable future, which will consist of learning the sky, visual astronomy, short exposure astrophotography with tracking (unguided), and image processing. I'll look into guiding systems when the time is right, but there's much to learn about the sky, imaging, and image processing before guiding becomes a necessary skill. It's not the best visual scope (immediate future is visual astronomy) given its aperture, but it's an improvement over 8x, 50mm binoculars!
The carbon fiber version cuts weight to 12lbs, which will allow me to use the Explorer Scientific EXOS-2GT with PMC-Eight mount without a strain on the motor. This mount is a budget mount, but after reviewing its functionality, I love it! 30lb payload capacity. ASCOM compliant. Belt driven with PEC. Memory drive to save settings. Wireless. 8 CPU processors. King tracking rates. 2 inch steel tripod legs with spiked feet. Bubble level (thankful). Illuminated polar scope. 2-star and 3-star alignment. It's accompanying app is open-source (my favorite aspect). Sorry, this is not a commercial.
I also added items to accompany the above investment (basic items):
1. Farpoint 2 inch laser collimator with 2 inch Cheshire eyepiece. I will use the laser to ensure the focuser is centered and use the Cheshire to ensure that the lenses are centered and collimated.
2. Orion Q70 38mm and 26mm eyepieces with Celestron 2.5X Barlow lens. This will give me 6 different magnifications depending on the location of the Barlow lens. Red LED headlamp. I'm still learning about vignetting and exit pupils of eyepieces. Any knowledge on the topic would be appreciated.
3. USB Dew Heater. 20000mAh external battery.
4. Lens wipes, microfiber cloth, and a glorified turkey baster for cleaning purposes.
Unfortunately, I won't have this setup for the Labor day event. Any thoughts on these items?

My Sky-Watcher 100mm f/9 is 12 pounds, IIRC. I'd be surprised if a 5" f/7.x isn't heavier...? In the absence of other info (and for safety sake) I'd also take that 30 lb mount rating with a grain of salt. I'm not dissing the mount, but it's relatively rare to find manufacturers that don't push the envelop with their payload promises (particularly in non-premium territory). Plus, I would prefer to stay at about 50% or less of the advertised capacity. Just my $0.02 in that area... I find astrophotography very interesting, but I only have one life to live, so I've never taken the plunge You'll need a suitable computer (i.e., laptop?) possibly in the field and also for processing, plus software. The learning curve is a cliff, from what I've seen but looks interesting nonetheless. I was starting out and possibly looking to do imaging later, I'd be tempted to get a moderate size Dob for visual / DSO work with the idea of adding a small, reasonably short focus ED refractor (70mm to 90mm, f/5 to f/6) later for imaging. One scope really won't cover the entire gamut of observing and imaging. You could save a few $$$ by borrowing a laser collimator to check your scope and correct it if necessary.Does that scope have an adjustable cell? At any rate, once set unless it takes a lick it should be good to go. There will probably be no provision (nor need) to adjust centering on a refractor. Fun to plan all this out, isn't it?

"Fun to plan all this out, isn't it?"
Oh yeah, something like that hahaha. I started searching a month ago: small quality refractor, then I got the aperture blues (I should make that a song)...larger refractor, then choosing mounts stage, then back to refractors, quick stop in the Newtonian phase with terrible aperture fever, back to small refractos then big refractors then smaller refractors, now the smallest refractor. Not to mention all the intermediate steps of glass quality, synthetic fluorite or CaF, focal length, focal ratio, price, etc. The time will be worth it. I'm enjoying the possibilities.
With much help from the cloudy nights forums, dylan odonnell, and trevor jones, I decided to purchase this setup. Unfortunately, the mount and diagonal is on backorder, but its alright. I'll watch the temperature slowly drop in the meantime.
1. William Optics RedCat 51 RedCat specific Erect Image Diagonal Celestron Luminos 10mm Eyepiece
2. ES EXOS-2GT PMC-8 DC Adapter (no guided tracking for now)
3. ZWO ASI183MM Pro Optolong L-Pro Filter 1.25 (I intend to produce only monochrome images for now) Adapters and USB cables come with the camera DC Adapter
4. Miscellaneous Celestron 12V 7AH Powertank Farpoint 1.25 Cheshire Eyepiece (for the diagonal...star test for lenses) Orion Astrogoggles (haha...I should have made my own)
First light will probably be visual use / sky scans (I love doing that). Second light will consist of star tests to check collimation and centering of the lenses and some imaging potentially.
