Hello, I'm on track to get an AP130GTX in the near future and I have been looking at adapters and spacing. It looks like there are lots of options for adapters and extensions, and I want to make sure

Evening, Seesaw weather here in North Florida. Frost one day followed by temps in the upper 70s F! Rain, fog and work have been the rule lately limiting wildlife imaging with the AP130EDFGT or the AP

I was considering trying to mount a Celestron edge HD 11” (28 lbs) side by side with a Tak FSQ106 (18 lbs) on a Mach2 for astrophotography, cameras (20lb est), this seems like it would be pushing this

Dear Group, The recent thread "Digital Readout for Focuser" stimulated me to thinking about tilt, which is relevant to focus and has been the topic previous posts. If there is tilt of the sensor, then

Hi Fellow astronuts, I'm clearing a path to the observatory so i can test mounts and scopes. Ice cold polar vortex heading our way with temps of -25 to -30 F. Perfect for cold weather testing. Of cour

I had a question, more out of curiosity. I recently ordered and received a QUADTCC for a TEC 140FL. Interestingly, it would not reach focus (needed more in-travel than available on the focuser). I had

I have a AP 1100GTO with absolute encoders. I took delivery of this excellent gear about 1.5 years ago and immediately ran into a tracking issue. I assumed that it was user error (and I am hoping it s

Good morning, Got 2h 46min worth of 2 minute subs on an old favorite, M42 last night before clouds rolled in. With the telecompressor you get a nice framing of the "sword" area. Tough to avoid burning

SSD use NAND flash chips to store data. The cheap drives use MLC NAND. NAND flash, especially Multi Level Cell (MLC) can develop errors when written at cold temperatures that aren’t all that cold (-10

Latest object with the 1600GTO. This is a work in progress. So far it’s about 39 hours of Ha. Sometimes I find myself Liking black and white more than color. Just because the detail seems to pop more

Hi Astro-nuts, Have been enjoying Mach2GTO (actually, I forgot it existing after started APCC) every night since I owned it for more than 6 months. I can take long exprosures as long as I want. This i

Hey gang, I just purchased a vintage AP 152 f/9 air-spaced triplet, and it’s supposed to arrive on Monday. I can’t wait to test it out, although that may have to wait as it’s apparently bringing a rar

Hello Astronuts, Finally got around to processing the heart of the Heart nebula, IC 1805. This was a difficult image for me because of continual thin clouds that prevented getting some of the fainter

Hello, what is a safe weight limit on the QRBASE *G* (The heading is incorrect mentioning QRBASE *M* ) when attaching a guide scope to the 130GTX? My goal is to attach a William Optics GT71 scope that

Many of my fellow A-P refractor nuts on this list also own Tak scopes. I thought this video was a interesting look into the production of Takahashi refractors. I'm trying to figure out the Japanese bu

Hi Astro-nuts, Finally managed to do a quick combine. 11 frames of 1200 sec each, narrowband Ha, taken with the 160 refractor on the Mach2 computer mount in very cold conditions. Not sure I want to do

With autofocusing becoming more and more common I am curious when someone is going to introduce a scope or focuser that has a digital readout to say exactly what position the focuser is in. Mike

Good Morning all, I have an older Mach 1 serial # M10288. It's new to me and my first AP product. I have seen a few numbers in different places but thought I might get an opinion here as to the limiti
