  1. SOLD Selling the filter for 70€ . Original price around 230$ (including shipping, vat and customs). The filter is in excellent condition, used only 3 times. No fingerprints, no scratches no dust (image attached). I will also handle the shipping through my post office without cost. If another shipping method is requested, then we'll have to to discuss the price. Contact me if interested. Clear Skies, Anthony
  2. Selling the Astronomik 12nm clip in Ha filter for 120€. Bought it for 270 usd including vat, customs and shipping so it's a really good price. The filter is still in excellent condition, used only twice. No fingerprints, no scratches not even dust (image attached). I will also handle the shipping through my post office without cost. If another shipping method is requested, then we'll have to to discuss the price. Contact me if interested. Clear Skies, Anthony
  3. hmm I'm not entirely sure but I think it always the same effect no matter the orientation. I never knew collimation error could show in the spikes although collimation looks fine with my collimation tools.
  4. Hello, I'm using a Bahtinov mask made for a 6 inch aperture on my 6 inch F4 Newtonian. However, The Central spike doesn't appear to be straight. I'll share an image I drew to simulate what I see. What could be the cause of that? Is it a bad Bahtinov mask or something with the optics? The star is in the center of the frame.
  5. Hello, I'm selling these 2 filters since I'm getting a mono astro cam. The filters are barely used and in perfect condition, no scratches, no fingerprints, not even dust. They are both amazing filters, probably the best investment I've made. I've attached some images taken with these filters, using a 100$ celestron newtonian, a 250$ Canon 500D and the infamous AVX. Also attached are images of the filters showing their perfect condition.

  6. I'm selling my my 70mm secondary mirror I used with my 150mm F4 newtonian for 100$ (final price). Shipping expenses (from Beirut, Lebanon) on me for free provided I use LibanPost for shipping. We can discuss using other shipping methods and maybe splitting the cost. The mirror is brand new, still have the original package and box, bought the telescope a month ago and used only twice. No scratches, not even dust (images attached). Excellent mirror, no issues whatsoever, 94% reflectivity and optimized for the offset of f / 4 Newtons, but it can be used up to f / 5. It's from TS, made in Tai

  9. I loosened the grub screws and reseated the focuser, nothing changed. I'm not sure how to square the focuser and how to check if it's pointing to the correct point.
  10. Hello, I've already posted this issue on cloudy nights but I'll post it here also maybe someone has some other ideas. I just received the TS UNC 6" F4 newtonian. According to TS,The scope is perfectly collimated before shipping, but will probably need to be recollimated before use.. However when checking the scope, I noticed that the secondary mirror is way off center and slightly elliptical (attached image). Is it normal for the secondary to be in such a position in an F4 or should I adjust it so it 's centered in both the x and y axes? According to TS, they calculate the perfect offset
  11. Thanks for the info! I actually decided to go with the TS UNC 6 inch F4. which is a step above the photon. I own the Skywatcher F4 Aplanatic coma corrector, do you think it's good enough to eliminate coma in an F4? I really hate coma.
  12. Hello, Is anyone here using the TS Photon 6" F4 newtonian? I'm about to purchase it but I have some doubts and questions: 1- Does it hold collimation well, at least in a single session? 2- Is it impossible to balance in DEC due to its small dovetail or is it possible but harder? 3- Is the focuser rigid enough or does it introduce tilt? 4- Will collimating it be a nightmare? 5- I'm really picky when it comes to coma, should I expect some coma on edges even while using the Skywatcher Aplanatic F4 CC? 6- All in all, do you advice me to buy it or have some other
  13. I always let PHD choose the star. That's not the issue.
  14. I didn't think of that thank you! But i doubt this is the issue since I've tried many different targets and different stars to guide on. But I'll keep that in mind. Thanks!
  15. One more thing if you don't mind, how did you plate solve the image and how did you know where the DEC and RA directions point?
  16. Btw how does pointing to the Zenith cause this effect if east heavy balancing isn't as it should. If you mean it could cause the RA axis to wobble, then that should appear in the guiding graph but it's not.
  17. That's very interesting Thank you! Most of my images tend to be similar to the 2 bottom images so perhaps I'm having some Dec issues. But what's confusing me is that my guide graph looks normal Here's a screenshot I took, unfortunately I don't have one showing the whole graph and the logs won't be of much help. I guess I'll have to narrow it down to flexure and/or dec error. Thank you that really helped.
  18. I've never had this issue even before I hypertuned the mount. I used to have >1.2" error with huge 4" spikes in the RA, and never got this exact issue. Now i have sub arcsec guiding with no spikes (very few spikes now and then but they do not always coincide with the bad images). Plus my reasoning is that even if there are spikes, they are usually really short and not enough to register such a bright second star?! It looks more like the scope moved entirely during image acquisition with no guiding correction which does not seem to be the case according to the guiding graph.
  19. Yep the rings have those plastic tips. My main issue is that I've been imaging with the same gear without any problems and suddenly I got this. Why would flexure suddenly appear out of nowhere. I always make sure the screws are extremely tight to avoid flexure. I will try to post some logs but the problem is that I was messing with the scope while guiding (checking for loose stuff, cable drag, etc...) so the log will have huge spikes that we won't be able to distinguish from actual guiding spikes and me messing up with the scope.
  20. Hello! I've been having this issue for a while now, and I've been trying to find the culprit with no success. This is driving me crazy. For some reason, I've been having weird stars in my image, where it's not a typical star trail, but the stars are actually doubled or tripled in more than 50% of my images. I've attached an image with different previews from different images, one of the images in these previews has good stars while the others have weird stars which seem to go in different directions in each image. Here are some notes: -I'm using a celestron AVX with the 8 inch n
  21. I understand that but my worries is star bloating since the CLS-CCD is also a UV/IR Cut filter. My camera still has LPF#1 but I'm not sure it's enough.
  22. is you DSLR modded without removing LPF#1 filter? If yes, are you seeing some star bloat? Thanks
  23. Hello, I've modified my Canon 500D (t1i) following Garry Honis' video; however, I did not replace the IR cut filter with a clear glass filter. I just removed the IR filter and put back together all the other filters. I'm using a Newt. with the Skywatcher Aplanatic coma corrector. Here's my issue, I already have the Astronomik CLS-CCD filter which is a light pollution filter as well as an IR blocking filter but I will be shooting M81/82 in bortle 4 skies this weekend so I'm not sure if using the CLS-CCD is a good idea. First, I'm in relatively dark skies with low light pollution, seco
