Hello! Any idea where I can find an M54 female to M60 male ring adapter? I need to order it online since there arent any astroshops where I live so I'd really appreciate if someone can link me to such an adapter. Basically I have a TS Optics 2" Adapter with compression Ring for Skywatcher Newtonians, TSM54-2 and I need to use it for my celestron newtonian which has a 60mm drawtube so I'll need some sort of adapter. Clear skies!
Hi All, So we were down at my parent's at the weekend and I've been working on my ongoing project to refurbish my old telescope so my Dad can use it - a Tal M from 1994 (!). Here's a picture of this vintage 'scope: As you can see everything is fine except for the fact that one of the tube rings has shattered in a fall. I need to replace the second tube ring but have no idea how to go about it. The rings are cast iron, and here is a picture of the broken ring for reference: What I want to do is either: Mend the broken tube ring Replace the broken tube ring Find some other way of attaching the telescope to the mount. It's an 88mm / 3.5'' reflector. Really nice 'scope - we gave it a whirl to check the optics and got it pointed at Saturn and it still shows a lovely clear picture. My Dad was careful to keep the tube somewhere the dust wouldn't get to it. Which of the above options would be the best solution to fixing this fine telescope for my old Dad?! DD
First time viewing and photographing this object - think I've found a new favourite to observe! My day was filled with heavy rain and whilst the sky did mostly clear, lightning could be seen in the distance and a mist left me with extremely condensated equipment, to the point where my laptop hit a BSOD with the mouse no longer functioning - so crossing fingers that after 24 hours of drying, it will be fine! The next time I attempt this object, I feel a nice 2x barlow will be in order, or even perhaps a 3x.
Takahashi FS-128 with 0.75X reducer/flattener on Vixen AXD2 mount 45 X 120s with Nikon D750 (90 mins) Processing in PixInsight and Photoshop I think the funny red ring artifact / glare / processing error actually enhances this nebula. Barry
Hi everyone! I was lucky enough to get a clear night last night, and have the first chance to test out my new Explorer 200p. Some of you may remember me posting a topic about how people lift such heavy things, and I got a huge amount of replies. In the end, I decided to split the scope into four parts: 1. Tube 2. Counterweights - to lighten the load as I move the mount 3, Accessory tray - So I could fold the tripod legs in 4. Mount + Tripod In the end, it took me about 15-20 minutes to set everything up, then I had to wait about 20 minutes for the sky to darken. In that time, I looked for an iridium flare, which the iflares app predicted. In the end, it never happened (Though I saw one at Magnitude 0 later on). Because it was nowhere near dark, I just pointed the scope at Vega. After that, I took a look at Albireo, looking as colourful as ever. I then looked for the double-double, but I struggled to split it - possibly because of seeing. After that, it became sufficiently dark to start DSO hunting. My first target was the Ring Nebula. I'd seen it with my old 150, but it was quite hard to spot. With the 200p, it jumped out at me! I added more zoom, and the nebula filter, and the ring shape was clear as day! My next target was M13, an old favourite. It was easy to see, with a somewhat mottled surface at low zoom, but when I cranked up the power, the stars were easy to see - much more so than in my old 150. After that, I looked at the Andromeda galaxy. It was a lot lower down, in hazy sky, so it looked little more than a hazy blob. Hopefully, it should be better when it's better placed in the autumn. Finally, I found the dumbbell. It was easy to see at low power, without the filter, but when I zoomed in, and added in the filter, it showed some good detail. However, even with all this, the dumbbell shape was still quite subtle. Still, even in photos, it's not as contrasty as the Ring. After that, it was getting on for eleven, and if I was up any later, my parents would kill me (not literally of course), so I came in. It took me about half an hour to bring my scope back in, and in that time, I let a couple of large moths in. Overall, it was certainly a good first observing session with my new scope! Thanks everyone for the advice you've given me with carrying my scope, as well as other things! David
Recently moved house, so my scope needs collimation and my house is barely unpacked! However a clear night arose, and my garden is south facing and Lyra looked far to tempting! I've moved in to a suburban environment. Weather: 22c | Strong North/East Gusts | High Humidity Location: Surburban Neighbourhood Optical Train: Meade LX90 8" SCT - Orion LP Filter - Nikon D300 Misc: Orion ST-80 with Guidecam - PHD desperately fighting the gusts! Imaging: ISO 1600 | 180s exposure length 40x Light | 20x Dark | 20x Flat Processing: DSS stack x40 (Best 80%) Levels and curves tweak in Photoshop, Nebula was processed seperately to the stars. Notes: The humidity seemed to make my D300's sensor explode with noise and the gusts left my stars looking a little eggy. I am considering using a 2x barlow and my ZWO ASI120mc camera to record footage of this nebula - just to see what structure I can resolve, though this is entirely exploritory as the camera has only been used on planets so far. I saw several "shooting" stars last night and even manually tracked a satellite for fun! Really happy my garden is south facing. Makes astronomy a lot more comfortable!
