Julien Dufour:I plan to use the fan all the time. Even in winter, and I get VERY cold winters here with some nights at -25C. Page 26 of the manual. I am also considering to get custom made dew shields. Does anybody know where I could get a rigid (aluminium) version though ? Astrozap has a few versions for Meade, Celestron, etc but nothing that I see for Tak.  |

Hello @Aygen , this one from Astrozap seems to be ok (215mm length) https://www.telescopesplus.com/products/astrozap-takahashi-epsilon-flexible-dew-shield-e160d-az-147 |

Julien Dufour: Salut @Julien, Thanks for chipping in. I am aware of this version which for sure does the trick. I am though looking for a more "rigide" version like the ones made in aluminium. You may wonder "why on earth just not to use the flexible model"  and complicate things ?Two reasons : a) I am planing to install a motorized dust/flat cap that I could control while lying on the couch  b) my rig will be permanently installed in my backyard observatory = I will be using Voyager and want to fully take advantage of the automation beauty.I will drop a message to Astrozap to check with them. PS: this thread has become the "must to bookmark" website for 160ed users ! Thanks to all of you for making this happen - and of cours to @Bill Long@Chris White for their incredible involvements. If time allows it, I will try to come up with a summary of the most important topics addressed over the last 15 pages  so that other could benefit from this knowledge database.

@Aygen i asked some guys in Germany to doing some high quality 3d printed dew shield. they arent heated but is not flexible and inside is velour. Maybe its could be an option for you, combine with a dew heater straps? i got a pic from him it s looks like this one.  The length you can define yourself. Hope a bit i could help you Best Attila |

Kaptas Attila: am i right that you mentioned once that in the front of the scope isnt necessary to be heated because of the fan? |

I think the 5v version of this same fan could run at lower voltages fine, there is a possibility that the issues I saw were due to the fan motor reacting negatively to smaller voltages. At 12V though this is not causing any problems and seems to be making star fields very clean of tube current errors. Bill, Once time allows it, would you be kind enough (as usual) to share a pic to have a view on the wiring ? I plan to have it connected to my Ultimate Powerbox. Thanks my friend. Aygen Fitted the Noctua cooling fan. Going to test exhaust mode first, as this is used in most imaging systems such as the CDK, RCOS, etc. Flipping the fan is pretty easy to do though.

I started my first mosaic using the e160 and QHY600. It's 2x2 and covers 7 degrees by 4.2 degrees FOV. Massive field with so much to see. It's just a WIP at this time, but thought I would tease those of you who are getting this scope setup right now with an example of going BIG.  |

I got my Optec installed and I think I have it collimated best I can tell. I wear glasses and my prescription is horrible (-14.5 in my right eye with some astigmatism) so it makes it hard for me to tell when everything is lined up well. Once I got the saddle off (those extra 2 hex screws inserted from the inside were a pain to get out) getting the new one installed wasn't too bad. I loosely installed the saddle plate and installed the Optec with the collimation tools installed. While looking through the collimation tool, I adjusted the saddle until the collimation looked close enough. I tightened the screws on the saddle and adjusted collimation a tad and ended up with the picture below. I think i need to adjust it a tad bit more to get it lined up a little better. Trying to get a decent picture through the tool with my phone was tough!   |

And so many details. Just exquisite for my eyes. Looking forward to seeing the final outcome. |

Daniel Carter: That collimation is close. The primary ring and secondary blot are offset to the northeast a tiny bit. |

Holy moly…. just received a heads-up from Takahashi. Earliest delivery of the 160ed in Europe expected in May 2023….  That's a bummer.

What filter size are y'all running to prevent vignetting? I know that with a mounted filter the clear aperture is typically 4-5mm less than the listed filter size; with faster optics you'd pretty much need the filter wheel right up against the sensor to properly illuminate. I'm speculating going from a 571 color to a 455 mono setup and wondering on 50mm vs 2" mounted vs short backfocus camera versions. |

Most of the folk here have the Astronomik MaxFr filters. For example, have a look at this : Ha MaxFr 6nm |

What filter size are y'all running to prevent vignetting? I'm using the short back focus QHY600 along with the Octopi tilt/backspacing adjuster. I'm using the MaxFR 50mm filters from Astronomik (along with DeepSky RGB filters and L2 luminance filter) and the Pegasus Astro Indigo EFW (based on Bill's recommendation). I think @Bill Long and @Chris White both are using the same filters. Based on the images Chris and Bill have posted, I don't see any issues with vignetting but I'm sure they can provide better information than I can. I just got my Optec mounted and I haven't had a chance to get the scope out under the stars yet so I haven't generated any data yet. |

What filter size are y'all running to prevent vignetting? I'm using 50mm unmounted. I get a little vignetting from the filter on IMX455, but flats correct it just fine. You also have significant light fall-off with this scope and the big chip. You lose about 45% at the corner of IMX455. Again, flats take care of this. Just dont get mounted filters, they would be terrible on this scope. Pairing with IMX455 is a good idea though if you are willing to put in the extra effort with backspacing and tilt. The FOV is monstrous. Take a look at my Abin page for some examples. |

@Bill Long @Chris White i got my noctua fan but i couldnt figured out how i can adapt it to pegasus powerbox, i am gonna need an rca end but i founded until now just an 3 pin to usb adptation. could you tell me or send me picture how you did it? thank you in advance. Best Attila |

Kaptas Attila: You don't power it with the dew heater you use a 12v plug. If you plug it into the variable output socket on the upbv2 then you can adjust the speed of the fan by adjusting the voltage. 12V DC Power Connector 5.5mm x 2.1mm, CENTROPOWER (10 x Male + 10 x Female) Power Jack Adapter for Led Strip CCTV Security Camera Cable Wire Ends Plug Barrel Adapter https://a.co/d/7OFQHRX |

@Bill Long Are you using the QHY OAG along with your Indigo? I got everything assembled last night and had issues with clearance between the QHY OAG and the LEO. I had to losen the 4 screws holding the focuser of the OAG onto the base so i could attach my image train to the LEO. The diameter of the OAG focuser is large enough that it hits the LEO. It looks like I'll have to either go to a guide scope or find a different OAG. I made do with what I had and got some first light images last night. I'll post one later...I definitely have back spacing and tilt to dial in. I didn't adjust any of that until I figure out my OAG issue. Thanks! |

Daniel, I can't answer for the QHY OAG since I don't have it. However, Evans from Pegasus Astro informed me two weeks ago that they shall release their "OAG INDIGO" by end of October / Early November". Have a look at it please : INDIGO OAG. The combination of both (Filter wheel & OAG) sum a 19mm + 14mm (33mm total) of backfocus. I am going to use the Indigo OAG along with the Indigo FW. Unfortunately, I will have to be very, very, very patient before setting it up on my 160ed  .PS : don't want to answer for Bill, but for sure he's not guiding with his Mach II ( )
