Thanks Gino, you are very kind.

I purchased the Baader UHC-S 'nebula' filter about a year ago when I was just staring out - I live in moderately light polluted skies and my main targets are nebulae so it seemed a good idea. Beyond that I really know very little about the relative performance of the different types of filters. I have been very happy with the images I have made with it but it does have a couple of downsides - quite strong colour shift ( that I try to correct in Pixinsight before I stretch the image) and it is highly reflective ( which seems to contribute to a bright disk around the very bright stars (eg. around Alnitak in http://stargazerslounge.com/topic/251987-flame-and-horsehead-nebulae-near-alnitak-in-orion-re-processed/)).

I'm sure others who are more experienced than me would be able to provide more detailed feedback.

Cheers, Mike

Reprocessed - I've tried to improve the colour balance - slightly toned down the red and tweaked the green. I think it is an improvement, what do you think?

      For sale is my beloved but now superfluous to requirements HEQ5 Pro for £650
      It's in a used condition as you would imagine. I've had it for about 4 years and found great success with this mount. Ideal for those beginning astrophotography and also good for visual users.
      I'm calling it "deluxe" due to the upgrades I've had done.
      - It's belt modified
      - It's had brand new bearings and grease
      - The backlash has been expertly setup 
      - It has the latest polar scope
      - The power port has been replaced with an aviation style port which is a lot more secure
      It'll come with the hand controller and at least 1 counterweight (if I can find the second it'll come with both). The polar scope cover has been lost. The counterweight is rusty as always. There is some marring on the counterweight bar housing as shown in the photos.
      It also will come with the modified power cable required also.
      Note: the power LED sometimes doesn't illuminate but the mount is still powered (please see the photo with the hand controller).

      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.

      Original price including VAT is 155 Euros (around USD 182). I got it for around USD230 including VAT, shipping and custom taxes.
      Selling for USD 100.
      Astronomik Ha 12nm Canon Clip in Filter: https://www.astronomik.com/en/clip-filter/clip-filter-canon-aps-c/clip-filter-eos-mit-astronomik-h-alpha-ccd-12nm.html
      Original price including VAT 194 Euros (around USD 228). Got it for around USD 270 including VAT, shipping and custom taxes.
      Selling for USD 150
      I am willing to ship them on my own expense using LibanPost (from Lebanon). Shipping might take time; if you would like to use some other shipment method please contact me to discuss the price. 
      Feel free to buy one or both together.
      Let me know if you have any questions. 
      You can also contact me on <private email address removed>
      Cheers,
      Anthony

      Hello,
      I know you've seen these questions a lot (unless your new) but I'm struggling a lot on if I should buy a Skywatcher 250px (10") or 200px (8") (dobsonians). I have a 5 inch and i'm looking for a big step up for noticeable changes. 
      Thank you

      Hi All,
      im totally new to this and have been getting setup over the past 3 months. I’ve purchased a Skywatcher 150P on a EQ3 Pro mount. 
       
      I have a 2x and 3x Barlow with 10x and 20x eyepieces. I’m trying to view and photograph Mars as it’s so bright at present and easy to see however I’m really struggling to see anything more than a bright ball when viewing and when photographing it’s just a blurry ball. 
       
      I have a canon 700d DSLR with t ring and adaptors  
      can folk suggest what combination of Barlow / eyepiece would be required to view Mars in all its glory and possibly lens and iso/exposure settings to get some nice shots too please. I’m aware I may need to stack and am tech savvy so this bit should be ok. I just can’t seem to get anything at present to process.
      help!!
