Hi,

Last night I made 22 exposures 10 min each to Ghost Nebula (IC 63) using Ha filter (Baader 7nm). The weather was perfect and the mount worked as a dream, best tracking i had ever.

Acquisition, guiding, stacking, calibrating in MaximDL, focusing in FocusMax and final processing (levels, curves, unsharp mask, reduce noise) with Photoshop PS2.

Set-up used - MN190 on EQ6/EQMOD, ATIK 314L+ mono plus True-Tech filter wheel, guided by finder-guider with SSAG, motofocuser controlled by SELETEK.

Thank you for your feed-back. I will try to obtain some extra exposures this night.

The tracking of my mount (belt drive) was unbelievable and if it will be the same this night, I will try some 900...1800 sec exposures.

I made some extra exposures in SII and OIII (105 minutes each) and I tried a Hubble palette with them. Calibrated and stacked on each channel, then color combine in MaximDL, weighted like 2xSII ®, 1xHa(G) and 2xOIII(B) and then processed in StarTools (Color TAB). The result was amazing for me, being first time when I processed a color image in StarTools. The details are not so obvious but the color is present and if you look carefully on both images (colored and uncolored), you'll find all details in both but color just in one.

You decide which is the best.

      In what was my final image with the Optolong L-eXtreme filter before I had to send it back to FLO, I turned it over to Cassiopeia. I knew that the Lobster Claw nebula was hiding there somewhere by using Telescopius and framing it that way (since it doesn't show in Stellarium). I realised that with the field of view achieved by the 80ED, reducer and 071mc Pro I could fit no less than 4, possibly 5 or even 6 DSOs in one frame. I love this part of the night sky. 
      The final image is composed of 31 x 300 second exposures, gain 95 at -5c. I ended up using the wrong dark frames by accident to calibrate it, and in all honesty I was too lazy to go shoot the right dark frames and re-edit it. So I just cropped out any nasty parts and edited it as normal. Not great practice I know but I really didn't get enough time with this target anyway.
      Either way I'm sharing the result and I hope you enjoy it!
      Clear skies all, keep looking up & keep them cameras clicking

      Hello All,
      I'm going through some of my subs which I captured earlier this year, but did not have a chance to process. This is my "War and Peace" nebula RGB subs processed which I captured on 22 June 2020, after the nights of imaging this nebula in Narrowband.
      Imaged at f6.3, 1280mm focal length, through my 8" SCT, cooled and modded Canon 40D for about 4 hours exposure time.

      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

      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.

      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.
