  1. Not a problem at all, thanks for the comment! Here's a comparison on Cloudy Nights between Baader 7nm and Antlia 3nm: https://www.cloudynights.com/topic/749764-comparison-antlia-3nm-ha-filter-to-baader-7nm-ha-filter/?hl=%2Bantlia+%2B3nm#entry10839989
  2. Thank you all for your comments! Yes, I'm lead to believe the smaller artefacts around Alnitak are microlens issues with the ASI1600MM-P.
  3. I recently purchased a set of SHO Antlia 3nm 1.25’ filters. Up until now, I’ve been using 7nm ZWO filters. Not having sold my ZWO filters yet, I thought it would be a good opportunity to compare the two. This will hopefully give prospective buyers a good idea of what to expect. Hopefully this is in the correct area of the forum! Like a lot of people, I simply can’t easily afford a set of 3nm Chroma or Astrodon filters, so having a set of 3nm filters at roughly half the price, with technical specifications that match the top-end brands is very enticing (I'm talking OD5). The data was
  4. Incredible images! I love the sunflower the best, the detail is so crisp!
  5. Wow! I really like the colours. It's amazing to see different objects in relation to each other.
  6. This was a couple of days ago. I've since done a little unboxing video, hopefully posting later today if anyones interested!
  7. £250 (includes postage). Purchased last June, immediately put into a filter wheel and not touched since (other than to remove them and put them back into the original packaging yesterday). See attached photos - no markings other than some slight dust (air puffer and/or flats will sort these out). Price as new is £325. Selling as I've upgraded to a 3nm set.
  8. Hello all, I have a Skywatcher 200PDS that's gathered dust for years as I've always been a fan of refractors. I've gotten it out multiple times to try and collimate it, but I just can't seem to get it right. I fear that I've now played around with it so much that I can't get the secondary and primary back in line. The primary mirror is now absolutely covered in dust, too. I like the idea of being able to take it all apart, clean it, put it back together and collimate it - but I'm at a point now where every time I attempt to collimate it, I think I make it worse! Because of this, I now don
  9. I've given up trying to get the back focus/tilt squared away on my Esprit 100/ApexED combo, so I've sent it back and ordered the standard SW flattener from FLO. Hopefully delivery won't be as long a wait as suggested on the website! Here's a couple of images I took when I needed a break from tearing my hair out. They're kind of first light with my Esprit 100 - though I'm not counting them as my real first light. NGC7635 - 26x300s Ha (7nm), NGC7000 - 6x600s Ha (7nm). Esprit 100, ApexED L, ASI 1600MM P.
  10. Having been clouded out and stuck in isolation recently, I've been re-processing some old data. This was taken with a DSLR, and comprises about 10 hours data in Ha and Oiii. 10-minute subs. SW 80ED. Both the original and new process are attached. As much as I like the newer version, I can see where I'm over-processing and relying too much on noise reduction. It's all still a learning curve!
  11. Thank you so much! Having access to new data at this standard over lockdown is such a blessing.
  12. Congratulations! Some amazing entries indeed, I gained some good insight into different processing techniques and combinations. Thank you FLO so much for continuing to post data like this for free!
  13. Soooo good. I prefer the orange/blue version - I strive for images of this quality!
