  1. Not a fan of this sliding up/down eyeguard design of my Delos either. I'd much prefer the twist up/down type of the Pentax XW or the basic simple rubber fold down type on the ES and Morpheus.
  2. As long as the sensor chamber hasn't been tampered with and there is no scratch or crack on the sensor window, the camera should be fine. As for the TEC cooling system, you can always ask the seller to demonstrate its function either in person or in a video clip to verify its condition. To prevent damage and prolong the life the TEC cooler, you should always avoid rapid cooling and warming.
  3. The 120ED is already very good optically, I doubt you would be able to see any "great" improvement from those 3 scopes you listed. Improvements will be there but whether they are worth 5000 euros or not is up to you. Honestly at this level the only major improvement I could think of would be bigger apertures for more light and resolution. But to get a noticeable difference compared to 120mm, I'd say 6" is the minimum (152mm f/8). Skywatcher Esprits are highly regarded by many astrophotographers, so I wouldn't dimiss those Chinese triplets so quickly (I love my APM107 which is another trip
  4. No direct experience with any of these 3 scopes. But if you were asking me to choose between Tak quality and more apertures purely for visual, I'd go for more aperture, in this case the TS 125. I've looked through a Tak FC100DC and Vixen ED115 before so I'm aware of the high quality views these Japanese doublets can produce. But compared to my own Sharpstar made APM107, there is virtually no difference. Yes they cool down faster than my triplet, but only by a small margin.
  5. No, you don't need a super sharp eyesight. You can zoom in while doing PA in Ekos. I do that quite often with my home made electronic finder for visual use (made of pi4 + pi hq camera + 9x50 finder + a gpio button + some self written python scripts).
  6. Do you guide while imaging? If yes, you could PA with your guidescope and asi120. Use your phone to VNC into astroberry then run the PA assistant in Ekos. No laptop required. Otherwise you could balance your setup with the DSLR and then swap for the asi120 just for PA. A slight imbalance during PA isn't a big issue.
  7. Up for sale are my trusted astro-modded Canon 600D and Lynx Astro dew controller. 1. Canon EOS 600D (astro-modded, NOT full spectrum) - £220 inc. UK postage **SOLD** Camera body 2 x LP-E8 batteries (1x Canon, 1x Duracell) Battery charger Neck strap USB cable Low profile T2 adapter Dummy battery for 8V DC power (compatible with 550D - 700D) 2. Lynx Astro 2-port dew controller w/ DSLR power supply (E8 dummy battery not included) - £55 inc. UK postage The Lynx Astro dew controller was purchased at the same time when the 600D was modded f
  8. Noticed a few gaps in the clouds, so quickly set up my 72EDF on the Scopetech. Finally managed to catch a sight of the sun during the greatest eclipse (11:01 - 11:20). There were quite a few tiny sun spots near the edge of the Moon.
  9. Full cloud cover here. No eclipse for me today.
  10. Already many M101, but still here is my entry: Date: 14/04/2021 Bortle 5 sky Equipment: Canon 600D modded, APM-LZOS 115 f/7, Riccardi 0.75x M63 FR/FF, SW AZ-EQ6 Pro, SW Evoguide 50ED + ASI120MM guiding Lights: 156 x 100sec Calibration frames: 15 Darks, 15 Flats & 15 Bias Dither: every 3 frames Software: BYEOS, PHD2, DSS & PS CS 2021
  11. What about guiding? As far as I can see the OP has pretty much covered everything needed to begin imaging. 80ED is a good starting point to experiment with various techniques and gears. Guiding is a must if he wants to get serious with imaging (unless he plans to get one of those premium mounts with absolute encoders). So I'd suggest he spends the money on a 50 - 60mm guidescope plus an ASI290MM (works better with an OAG than 120 if he images with the 8" SCT). The rest could be spent on some sort of remote control of the imaging rig (laptop, compute stick or pi).
  12. For imaging, there is RASA that fits your short FL SCT requirement. Technically it isn't an SCT as it only borrows the schmidt corrector and the spherical mirror from the SCT but not the folded light path. As for visual afaik such fast instruments (f/2 - f/3) only exist in the form of custom made newtonians (large dobs).
