  1. Finally got to image Mars this year after some appauling weather in the UK. This was my first time out using the ZWO ASI 224MC on a very cold eve. I think i've probably the maxed out my equipment (Skywatcher 200p) and the location (back garden in the middle of an estate) for this image, so pretty pleased with the results. Its 15% of 11000 frames stacked using Autostakkert, and Registax used to bring out some detail. Equipment used: Skywatcher 200p with dual speed focuser, EQ5 mount with dual axis motors Tal x3 Barlow ZWO ASI224mc with IR Filter Lenovo x270 laptop running SharpCap Image Processed in Autostakkert, Registax and photoshop
  2. Hi All, Sharing some more Mars images, quite possibly the last images of Mars that I'll be spending time on capturing this season, but the last image, 14th November has something strange on it.. two streaks which look like smoke plume, volcanic like, smoke plumes being blown in a direction away from the eruption.... Is it possible that Mars is still active?
  3. Mars was taken at night between 20:57 and 22:29 UTC. Equipment used: Celestron SCT C8, Barlow 2x, GSO #29 (dark red), ASI120MM Mini, HEQ5 mount. Animation was prepared from 20 images with drizzle 150% (the best 10% of frames from 60-second movies): One of the best images from 21:55UT:
  4. Hello all, Sharing my latest image of Mars, taken with a Skyris 618C CCD through my C8 8" SCT at f33. The size of Mars is already noticeably smaller than it was only a couple of weeks ago. CS MG
  5. Hello all, It's been a while since I posted any images on SGL, as I was collecting some Mars images during the opposition 2020 season. I'm sharing with you my better quality collection of Mars images which I have imaged during September and October 2020. For some reason I had many more nights where the seeing was so bad that my data was very blurry than nights where the detail was crips and I, either, threw out more images or gave up on imaging nights than ending up with a half decent image. These images were taken with my Celestron 8" SCT using a Skyris 618C CCD at f33 (6700mm focal length) all riding on the CGEM and captured in Firecapture. All images are De-Rotated stacks in WinJupos of the best 10% of frames from 10-20 90 second videos captured at 60 fps... number of videos I used was depended on the clarity of the atmosphere and image capture quality on the night. The date and time written in the caption is in UTC and the median time when de-rotated. Clear Skies, MG
  6. First the disclaimer. This is my first attempt to sketch Mars, or indeed any planet. Also, it started to rain and I had to abandon it with some urgency (hence no orientation marker). I used a HB pencil and a blending stump. But I think I can see a couple of features that match Ade Ashford's app. The Wratten 21 filter improved the view enormously (although you may find that hard to believe looking at the picture) helping show the surface detail and improving the seeing. I tried it the day before in my 80mm refractor, but that just made the image too dim, but on the 115mm it was very good, so I recommend it to anyone with 115mm or larger. I tried sketching the moon (Plato) several years ago, but SWMBO pronounced it (I'll paraphrase her here) more Feline Anatomical than Selenographical. While this one may look more like a two year's old attempt at drawing a rabbit, at least no one can confuse it with the rear end of the cat. So regardless of the criticism I receive here, I'll give it another go tonight (weather permitting).
  7. Hello I am trying to find ways to observe more detail on Mars. I am observing him between 35 degrees and 50 degress altitude. He is SOOOO bright that the intensity of the light is washing out any surface detail. I can just about make out the Southern polar cap and can see (just) some surface shapes but it's the brightness of the planet that is (ironically) the issue. I do have some colour filters which I can use over the eyepiece. Any tips for which colour is best, please? I have tried observing with various magnification, ranging from 8mm to 32mm. My focal length is 2800mm and focal ratio F10, (CPC1100) Any tips /advice / help all glady welcomed, thank you. Bonus - tonight I got to see Uranus, looking like a little light blue / green ice ball and a transit of Ganymede's shadow on Jupiter! Very cool. Siouxsie
  8. Hello, I'm new to astronomy and have recently brought a low budget telescope (about £60). I've been out a few time to view Mars and the moon. Obviously I can view the moon clearly and with great detail but when I go to view Mars all I can see is a bright circle. I'm not sure if I'm being daft or what, but I can't find anywhere online that has an answer to this. Details about my telescope are: It's a reflector telescope Model 76700 Diam: 76mm Focal length: 700mm
  9. https://youtu.be/yG9BFrbyG9BFrb1k1s Guys any suggestions on how to get better results using a 5inch reflector? For this I used a smartphone to capture 10s video at ISO:200 ,shutter: 1/100 Preprocessing in PIPP and stacked in registax with some wavelets too.
  10. Hi everyone. Thanks for looking. I know we're inundated with Mars pictures at the moment but I've not seen buckets of time-lapse and this marks a significant personal best for me so I really wanted to share it. I've not had seeing this good for a long time, especially with a planet this high above the horizon (I'm looking at you Jupiter & Saturn.....). Only 12 frames spread across ~1 hour, but nice to see some movement. One single still as a bonus too Edit to add acquisition & processing: Skywatcher Skyliner 200P reflector (off my dobsonian), 1200 mm, unbranded 3x barlow for 3600 focal length, f/18 Skywatcher NEQ6 Pro mount ZWO ASI120MC-S - gain 33, 20 ms exposure, 2000 frames per video Each video recorded with 5 minute spacing. 12 recorded in total. Stacked in Autostakkert 3, best 30% of frames. Wavelets, colour balance, and tweaks in Registax 6. GIF assembled in Photoshop with a few final contrast and levels tweaks.
  11. Having taken some images last week when we had a good spell of seeing I had pretty much filled up my hard drive with files and I've since been clearing and sorting what I have. The attached are a few mars animations showing the planets rotation over an hour or so on the 16th and the 21st to 22nd of September as well as the best still I have so far processed. I'm still not happy with my processing but hopefully that's a skill that improves over time. All taken on 8.5 inch newt with asi224mc. The first two at around f18 and the last and the still at f33 with a combination of barlows and bits (basically imagine if Frankenstein made an image set up) All processed through pipp and as3. Still was taken from 35% of 15000 then registax for wavelets. Right then, back to my digital housekeeping, only another Tb to sort!
  12. Hi guys, I am a newbie on this forum, this is my first topic here but I would like to show you my recent planetary imaging results. I started to catch the planets with a dedicated planetary camera last month but never thought that a small 4" Maksutov can show such small details. The equpment I used: SW 102/1300 Maksutov 2.25x Q-turret Barlow lens QHY5L-II color camera EQ-3 GOTO mount All the images were taken on differend countrysides in Hungary. I hope you will like it Also, please share your images taken with similar OTA, I'd like to learn some tricks from others as well Jupiter's 15 minutes of rotation. Captured with Firecapture, processed in AS!3, Registax and WinJUPOS (2020.08.21) Saturn, 1 hours stacked with AS!3, processed in Registax (2020.09.05) Mars, 3 hours of rotation. Captured with Firecapture, stacked with AS!3, processed in Registax. (2020.08.22) Mars again, 5 minutes stacked in AS!3, processed in Registax. You can see also Olympus Mons and Arsia Mons next to the terminator (2020.09.05) Finally, a result of a Hungarian star party where I learned how to use properly my equipment This time I borrowed an ADC for Saturn.
  13. Images taken between 03:01 & 03:52 this morning. C9.25; CGEM; ASI385MC; ZWO ADC; ES 3x Telextender; Baader neodymium filter. AutoStakkert!3; RegiStax6; PS CS4 Extended. Socially distanced comments/suggestions welcomed as always.
  14. Hi, A few sketches from last night 2x Mars and also one of M2. 1st Mars one was in poor seeing, 2nd was better. M2 view was affected by heavy moonlight. Also observed (but didn't sketch) some Hercules doubles, Uranus, Neptune and also M45 by naked eye. Best night for a while! Lee
  15. Had a great view of Mars last night at ~11.30pm. Best I've seen it so far this year I think. Sketch below. I think the darker regions in the S are Mare Cimmerium, Mare Sirenum and Mare Chromium. Could also clearly see the South Polar Cap and limb cloud at the following side of the planet.
  16. Some quick results on Mars from the morning of 20 July. The seeing was good and Mars at a good altitude. Equipment: CPC800, ASI224MC with IR-cut and IR-pass filters, ADC. The surface features show more clearly in infrared. I forgot to try a Barlow lens on this small target, but have not had any good results with the cheap Skywatcher x2 Barlow in the past. So these images are kinda small; I was going to x2 them in Photoshop but am having a problem with my network just now. The surface detail checks out as Syrtis Major and Hellas with the southern icecap.
  17. Perhaps the title is lying a tiny bit... After sleeping for one hour I woke up not able to fall asleep again after numerous attempts. I took the obligatory gaze outside at the bright summer sky with some faint noctilucent clouds towards the north. Jupiter and Saturn looked beautiful in the south and that was when I felt a sudden itch to get out my small grab and go setup. I quickly grabbed my tripod, mount-head and telescope to head downstairs to the parking lot where I quickly set up the scope. Cool-down was almost not a problem because of the hot 20 degree air which was very comfortable observing temperatures. Starting with Jupiter, after I had achieved focus on Altair, the two main cloud bands very obvious together with three of its moons hovering like pin-points around the perfect round sphere. I've previously been a little disappointed with the view of Jupiter with this small Skywatcher Evostar 72ED DS-Pro but I blamed it on my own patience and this morning I proved myself right. After studying the planet for a couple of minutes I noticed the Ganymede shadow transit located just above (almost on the edge of) the northern equatorial belt and letting the planet drift through the FOV at 90X magnification with the 4.7mm explore scientific eyepiece the shadow together with the bands popped at me at times of great seeing. The moments where you're almost "falling into" a better and better planetary image is truly amazing and the small 72mm scope did a very good job also resolving the shadow transit as a "globe" rather than a dot. Only rarely could I tell the slight variations in the two main cloud bands of Jupiter but this was very difficult with only 72mm. Saturn proved to be equally fascinating just like every other time I point the telescope towards the ringed planet. Immediately slight banding was visible on the planet and the rings were very defined with the Cassini-division visible in moments of good seeing but really standing out in brief moments of very good seeing. The small evostar 72 has no problem on Saturn whereas more patience is required with Jupiter because of its low contrast features. Saturn never disappoints. Moving on to Mars I noticed how it had increased slightly in size since I observed it last time about a month ago. The southern polar cap was still very obvious but for some reason I recalled it being even more noticeable last time I observed Mars but I could be wrong. Right above the polar cap was a dark spot which extended to the planet's equator but not covering the entirety of the disk's width. I didn't notice any features on the northern half of the disk. The evostar does a surprisingly good job on Mars, which often causes problems for other doublet refractors with trouble correcting the red part of the visible spectrum. The evostar doesn't have much unfocused red light around the planet and the view isn't "mushy" like it would be in cases of a badly corrected refractor. I love my grab and go setup but I also feel like I need a higher magnification eyepiece since my current weapon of choice is my 4.7mm explore scientific 82 degree eyepiece which delivers about 90X magnification. I've almost always felt I could easily push magnifications to the plus side of 100X and the Nagler zoom 3-6mm is ranked very high on my wish list:) August this year marks the first year of owning the Skywatcher Evostar 72ED DS-Pro and I haven't had a moment where I didn't love it. The size of it is perfect and the supplied flight case for the scope is airline portable together with some room for accessories. The optics are very good even for decent planetary observing like it was the case this morning, and I feel like I haven't utilized the scope's abilities entirely just because I think it could take even higher magnifications. I have also used it for astrophotography on my star adventurer which yields very good results with the OVL field flattener and my old Nikon D3300. This post ended up being quite long but I hope it was worth the read anyways. If you're considering the Evostar-72 I once again highly recommend it if you couldn't already tell from this post;) Clear skies, Victor
  18. Following my effort of 22 June, being unable to lift anything heavy, I set up my lighter weight telescope in a different position from the previous night to get some images of Mars. This was the first serious use of my EQ-5 with Synscan upgrade. I set up the gear and left it tracking the assumed GoTo position of Jupiter for a couple of hours. At 2am, Jupiter was not within the 25mm eyepiece field. Not so impressive. I repeated the imaging of Jupiter and Saturn, and also took images with the ZWO infrared filter. While slewing back to Jupiter, now apparently past the meridian, the mount did a meridian flip and ended up pointing at a street lamp. I was not impressed. Eventually Mars emerged from behind an adjacent building, and I took images in IR, visual, and visual with a x2 Barlow lens. Equipment: 127mm Maksutov 1500mm fl, ASI224MC camera, ADC, x2 Skywatcher Barlow, best 20% of 5000 frames (visual), processed in Registax6. EQ-5 Pro Synscan mount. Key: Monochrome images were taken in infrared. Larger Mars image with Barlow. Mars was jigging about in the poor seeing by nearly its diameter (11"). Note: the hottest moon (Io, to left of planet) seems slightly brighter in the IR images. I think the 127mm Mak punches through poor seeing better than larger apertures.
  19. I imaged Jupiter, Saturn and Mars this morning around 3.30am in the interval between 'high enough' and dawn. Equipment: CPC800, ASI224MC, ADC. Captured with Sharpcap, processed with Registax6. Used best 20% of 5000 frame videos. It's so long since I did any planetary imaging that I had to re-learn what to do. The Jupiter and Saturn images seem under-exposed.

    Opposition of Mars

    Mars at Opposition, best placed for viewing ie at its largest apparent diameter of 24.3 arc seconds, visual magnitude -2.8 and a distance of 57.8 million km. It transits at 1.15am but at a height of only 13.2 degrees above the horizon from London. Best bet is to get on a plane and head South!
