To celebrate the 25th anniversary of Sir Patrick's DSO catalogue, I've added the available Caldwells to my basic Marathon search sequence. 

Those interested may be pleasantly surprised by how many of the additional treasures are only a short hop from a given (or en route to the next) Messier.

The sequence for 40°N can be found at the SEDS Messier Marathon homepage or at my blog.

Peace, Stephen

      Hi,   I've recently received a pair of Bushnell 10x50 Legacy binoculars as a gift and while the image quality is generally very good, I've noticed an odd problem when looking at Venus or the Moon through the right eyepiece or through both the eyepieces together. In the case of Venus, there's a ray that emanates from it and goes at a certain, fixed angle. The ray moves in both directions depending on the movement of my binoculars and when I saw it the first time, I thought it was a shooting star. I tried rotating the binoculars and the ray's angle correspondingly moved with it; I looked at it through the right eyepiece but with my left eye this time but it was still the same. In the case of the Moon, it's a small white sphere that moves in a certain direction instead of a ray of light. Since this doesn't happen when I only look through the left eyepiece, I'm guessing there's a problem somewhere in the optics on the right-hand side of the binoculars.   Could you please help me figure out what might be causing this issue and how I can rectify it (if at all possible)?

      Thank you for your help.

      Hello all, my name is Paige. I am a college student and new to the stargazing community. I know all about the constellations and astronomy, but i’ve never bought anything to see the stars up close. I’ve read through the forum and come to the conclusions I want to start with some well built binoculars and eventually get into telescopes. The 7 x 50 seem to be the common starting point but I would love to get something with a bit more clarity, and preferably still handheld.  I’ve also read up on some binoculars already and the big brands that jump out are Celestron and Orion, so I would love some opinions on those because they don’t seem to be reliable in the long run. I only have one shot on a good pair and I dont plan on buying any other equipment until i’ve mastered the binoculars! Price range up to around $300 so any tips would be amazing!
      Thank you, happy sky watching 🌌

      Hello, I am an amateur astronomer that wants to get into deep-sky astrophotography. I already have a telescope which is Celestron Nexstar 127 SLT but it doesn't meet the requirements to take photos of wide field nebulaes/galaxies, (Ex: Orion Nebula, Andromeda Galaxy). I need some help on what to use and afford! It has to be under £550.
      I need a 70 or 80mm optical tube, with a mount that does polar alignment and can be attached to the optical tube then I need a Canon camera that can take long exposure high ISO photos and last a filter or two to help reduce light pollution and contrast the nebula/galaxy more!
      This is just for my birthday, I do not expect the best!
      I just need a beginners setup.

      Hi! I've recently acquired a new Astromodified Canon rebel XT and I've tried to take pictures of nebulas using it but I've noticed that there are these weird black artifacts that keep appearing in my images. Would like to know if anyone has experienced this before? Or are these dirt/dust specs on the camera, filter, and telescope glass? I've attached some of my edited and raw pictures for your reference. The black artifacts can already be seen in the raw image of the horsehead nebula and after stacking I think it got amplified. Anyway, advance thanks and I hope everyone's doing well.
