Upgraded M51

Recommended Posts

Hi all,

My last imaging for this season resulted in 11 x 10 minutes on M51, but I already had 23 x 15 minutes from previous seasons so here is some 7 1/2 hours of data.
The 23x15 minutes subs were taken under a pretty dark sky (SQM-L = 21.65), while the rest were approx 21.5. Used a modded Nikon D7000 in a 8" Meade LX200-ACF on HEQ5 Pro, guided with NexGuide. I am still amazed that stars were pinpoint in all 23 of the 15 minutes subs. I guess it helped that the OTA was pointing near zenith so flexure and mirror lock issues should have been minimal. Nowadays I stick to max 10 minutes subs.

Ragnar

      After a few months of getting used to my new 8 inch beast, I decided to start astrophotography (luckily today is Black Friday in most tech shops in my country). So I decided to drop the idea of buying a DSLR and started thinking about getting a webcam. The thing is that I want to try deepsky AP, so i was wondering, is there a webcam that could get me good results for DSO AP? Don't worry, I don't want anything too fancy because I'll be happy with entry-level images. (i saw some nice Andromeda pictures with 20GBP cameras on this forum so I'm confident that it would work).
      My budget is ±100 GBP, which in my opinion is more than enough for a good webcam . So... is it worth getting a webcam? Or is there something better? Should I wait and raise more money for a DSLR?
       
      Thanks a lot!

      I would like to share my first picture ever posted and the first real picture captured with my Tecnosky 80/480 APO FPL53 Triplet OWL Series (not counting the test shots for "first light").
      This is IC 1805, also known as the Heart Nebula, taken over 4 nights, under my Bortle 5 home sky.
      Total integration time: 8h 52m 20s.
      Here are the acquisition details:
      Mount: Sky-Watcher NEQ6 Pro
      Telescope: Tecnosky 80/480 APO FPL53 Triplet OWL Series
      Camera: D5300 astromodified
      Reducer/flattener: Tecnosky 4 elements, 0.8x
      Guide-scope: Artesky UltraGuide 60mm f/4
      Guide-camera: ZWO ASI 224MC
      2020/10/07: Number of subs/Exposure time: 1@60s + 80@90s. Notes: No filter, Moon 70% illuminated
      2020/10/13: Number of subs/Exposure time: 2@60s + 11@180s + 1@200s + 12@240s. Notes: L-Pro filter, no Moon
      2020/10/27: Number of subs/Exposure time: 59@180s + 1@240s. Notes: L-Pro filter, Moon 88% illuminated
      2020/10/28: Number of subs/Exposure time: 48@180s. Notes: L-Pro filter, Moon 93% illuminated
      Total exposure time: 31940s = 8h 52m 20s.
      Pre and post-processing: PixInsight 1.8.8-6.
      Unfortunately, the best out of the 4 sessions (no Moon and L-Pro filter) was also the shortest one. But, after waiting for 5 months for my telescope, I couldn't pass up the few clear skies opportunities I got since it arrived, Moon or no Moon.

      Here's a link to the full resolution image: Heart Nebula (IC 1805)
      Thanks for looking and commenting!

      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.
      Astronomik CLS-CCD Canon Clip in Filter: https://www.astronomik.com/en/filter-gegen-lichtverschmtzung-filters-against-lightpollution-lpr/cls-ccd-filter/clip-filter-eos-mit-astronomik-cls-ccd.html
      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

      I shot this yesterday from a Bortle 6 backyard. Edited in Pixinsight and Photoshop
       
      If someone here knows how to remove purple stars, please  help me . I tried defringing but it didn't really work.
      Also the date is wrong should be 9.10.2020. lol

      I have already posted my first astrophotographic session report in the telescope review thread: Tecnosky 80/480 APO FPL53 Triplet OWL Series - Review. But since that is more of a general review/diary of my experience with the new telescope, I feel some of the issues I am having are being buried and they will probably get more visibility if I post them - in a more synthetic version - in a dedicated thread.
      So, a few nights ago (October, the 5th) I took out my new telescope for its first light. All the photos have been taken with the 0.8x flattener/reducer and the Optolong L-Pro 2" filter attached to the reducer. The camera is an astromodified Nikon D5300. The only processing the following pictures have consists in this:
      - AutomaticBackgroundExtractor
      - ColorCalibration
      - Stretch
      Here we have a 90s shot of M31.

      And here's a mosaic generated with the AberrationInspector script.

      What I do like:
      - tightest, smallest, roundest stars I have gotten since I started doing astrophotography at the end of January. Obviously comparing it to what I have been achieving with a kit 70-300mm zoom lens, these can't be anything else but better by orders of magnitude
      What I don't like:
      - star shape not consistent in all areas of the image
      - residual chromatic aberration, especially on stars that are not round: there's clearly some red and blue edges visible
      I didn't expect this from an apochromatic refractor, but maybe it's just because the stars are kinda "smeared", so not all light is focused at the same spot? I don't see this around the center of the image (or, at least, the problem is less pronounced). Maybe I have some tilting in my imaging train/sensor?
      I have been doing some reasoning about it and it seems like a combination of tilting and/or backfocus spacing. According to the following image about backfocus spacing:

      if the stars are elongated radially, the sensor is too close, if they are elongated tangentially, the sensor is too far. But to me it seems I have a little bit of both: in the top right corner, for example, the stars look radially elongated, in the bottom right, they look tangentially elongated. Top left they look tangentially elongated, bottom left also, but a little less. Seems like there has to be some tilting as well, otherwise they would all have a symmetric shape on all corners, correct?
      How do I determine - is there even a way - if the issue is due to tilting only, backfocus only, or the combination of the two? Is there a sure proof way of checking for tilting? Like, rotating the camera and taking pictures with, say, the camera at 0°, 90°, 270° and 360°? If there's tilting, the pattern of the star shapes should follow the camera, correct?
      I also tried splitting the channels in R, G, and B components, doing a star alignment of the blue and red channels with the green as a reference, and recombining the channels. The blue and red edges become a lot less evident, which is good, but obviously the star shapes remain the same.
      In my Telescopius gallery you can also find two other images, Capella and Capella Mosaic showing pretty much the same issues.
      Also, one issue with the guide camera: ZWO ASI 224MC. When attached to the guide scope (Artesky UltraGuide 60mm f/4), I can't seem to get a "sharp" focus, I even tried on the Moon, and the best I got was a soft lunar disc, with some major features visible, mainly by change of color/brightness (the maria, for example), but no details. The image still seemed blurred/bloated. Is it because of lack of IR blocking filter? I tried the same camera attached to the main refractor, with the L-Pro filter (which blocks UV and IR, as well) and I could focus perfectly. Do I need an IR block filter for guiding or even if the stars appear a little soft, the camera guides just fine?
