First time i used my new astrotrac mount. I wanted to start easy and only attached an 85mm lens to my D5300. This is a 8 minute exposure at Iso 100 and f4. I`m not so much impressed about the performance of the lens, but i think the performance of the astrotrac is quite good. The image scale is 10" per pixel. -
For those struggling to collimate there Astrotrac Polarscope (as I was), check the tube housed in the main body of the scope for flex and ensure it is the right way round. today I removed the tube and swapped it around, this made ALL the difference, collimation was a breeze after this. I have already swapped out the grub screws for thumb screws and remember to make tiny adjustments each time.

I'm off to Kelling Heath Star Party again in a few weeks and I'm having a sort out of stuff to sell at the event. I'll be on pitch 167 (the new area behind the loos on the yellow field) from Wednesday 20th September. Amongst possibly a few other things, I'm planning to have the following items for sale Astrotrac (Mk1) with custom polar scope and battery pack. This has given me years of faithful service, but I've realised that, taking only 5 minutes subs with a 50mm lens, I just don't need the accuracy this lovely bit of kit can deliver. I've downgraded to a secondhand iOptron Skyt

Hi So this thread will cover in fact PoleMaster, Astrotrac and GiroMini because this is my setup.I bought the PM (PoleMaster) since the Astrotrac has a fail polar scope (no matter how you fiddle about it), and of course the dedicated adapter to mount PM on the AT (Astrotrac) arm. PM is a real joy to use, but somehow I suspect the AT polar arm has some "issues", so I bought another PM adapter for AZEQ5 and mount it right on the GM (GiroMini).It was based on another suggestion I made to a fellow astronomer, but nobody did it. Long story short, below the new adapter in place. I am

I was wondering, is there an alternative to the ATTH3010 declination unit one could use with the Astrotrac? Counterweight is important, because I'd use a 90/600 APO.

An AstroTrac and a Red Dot Finder I have been looking for something like this for a few years. Finally found it - so thought I would share. It's an adapter that allows you to mount a Red Dot Finder "firmly" on a camera Hot Shoe. From Geopitik via Teleskop-express. It has a screw (with a nylon tip) that you can use to clamp it down (clamp it up to be more accurate) so it does not move. Happy I found it! Cheers Ian PS - Yes - that's a PoleMaster lower left. ;-) PPS - And a guide scope upper right. PPPS - Dying to see if this lot works! ;-)

2013-02-14 - NGC2244/Rosette - All Lights Combined
StuartJPP posted a gallery image in Member's Album
From the album: Deep Sky Objects
This image is a combined set of subs over multiple nights (a first for me). NGC2244, Rosette nebula taken from my heavily light polluted garden in Leeds. This was to test my modified Canon 1100D and the Astronomik CLS Light Pollution EOS Clip filter. Modified Canon 1100D with Canon 500mm f/4 L IS lens @ ISO1600. AstroTrac TT320 Mount. 20x 60 second lights from 2013-02-03 45x 60 second lights from 2013-02-14 20x Darks 20x Flats 20x Bias Stacked in DSS and processed in PS. -
Had a lovely imaging session on Suday morning in "runoffshed's" back garden with the PST and DMK41, this is my fourth outing with this equipment and the first time with a barlow added. The atmosphere was very steady with the only interuptions coming from Sybil the very curious cat and by John generously providing tea and bacon butty's, this sure beats messing around in the cold and dark The second image is an inverted close-up which to my eye looks like a distant church with a spire next to a tree on top of a hill, needless to say I'm very pleased with the results I'm getting from the little

Details of a modification i carried out on my Atrotrac to reduce play in the pivot bearing. Item had been returned to Astrotrac but was found to be working correctly in line with expectations.

Hi After years of failing to get a decent solar image with a DSLR on my PST I finally bit the bullet and bought a secondhand DMK41. WOW what a difference, I was beginning to think I had a dodgy PST but now I'm as pleased as punch. I've learnt a lot from looking at the superb images in this section and getting tips on which stacking software is best to use, I settled on AutoStakkert!2 for stacking and Registax 6 for sharpening plus a bit of Photoshop to finish it off. This image was shot on 11-11-2012 with the PST mounted on my Astrotrac. Mel

Here's my latest imaging attempt using the AstroTrac 320AG. M45 imaged from Ag Nik in Crete with a gibbous waxing moon. 18 x 165 second subs, Nikon D40, ISO 800 with 55-200mm kit lens @200mm, f 5.6.

This is second light with my AstroTrac. Andromeda Galaxy from Ag Nik in Crete. 10 x 120s subs, Nikon D40, ISO 800 with 85-200mm kit lens @ 200mm. Stacked and with small stretch in DSS. Won't win any prizes, but I'm really happy to be doing some imaging on hgoliday! When I get home I'll try to clean up the egg shaped stars.

A very enjoyable imaging session last night at the Rollrights with Astrosurf (http://stargazerslou...ing-worked-m51/) and while she was muttering to her autoguider I set up my Astrotrac. The wind had died down by now so I thought I would try out my new 300mm lens on the modded Canon 550D, target was the Crescent Nebula in hydrogen alpha and I managed to get 25 usable 4 minute subs within the 2 hour run of the Astrotrac. All processing done in Photoshop and I must say I'm very pleased with this image as a first attempt with this combination. Mel

I'm pondering investing in an Astrotrac based system, purely for photography and not for observing. I've found that Telescope Service sell an Astrotrac travel package that substitutes the Manfrotto tripod, geared head and ball head for a 'Triton' branded tripod, with a 3D head and a ball head: http://www.teleskop-express.de/shop/product_info.php/info/p3812_Astrotrac-travelset---complete-set-with-tripod-and-ball-head.html It's considerably cheaper than the Manfrotto equipped package (~£590 versus ~£900) - just wondered if anybody had tried the Triton gear? Searching the forums has shown a cou

Hello everyone, Last wednesday, I tried my first shot with an Astrotrac, which I borrowed from a friend before making the jump and buy one. And I must say that I'm quite amazed by its tracking capabilities, even without an autoguider. I know that the lens I used has only 85mm of focal length, but I only got a 5 pixels drift during 45 minutes of imaging : that's quite impressive Enough chitchat, here are the images : 5DmkII, Astrotrac, 85mm f/4.0, ISO 800, 14 x 60 seconds exposures, 15 darks, 50 bias, no flats, PixInsight for everything except the colors/saturation.

Evening SGL, i recently purchased an Astrotrac TT320X-AG and thought i would give you my thoughts and share my results so far. Any critism and tips or tricks that may help me improve are very welcome. My Astrotrac arrived probably about a month ago now so i have had roughly 2 weeks of Moonless sky to image. This is also my first tracking platform after doing fixed tripod for about a year so its been a great fortnight, as i feel i have squeezed just about all i can out of 30 second exposures! Dont get me wrong, fixed tripod AP is great but i've had an itch to go deeper for quite a while now. Th
