How to prevent dew from building up on the external parts of a dob? (e.g. the mount, the casing around the mirror)
-
I use a modified Canon 600D, a Tamron 150-600mm Lens and a Skywatcher Star Adventurer 2i Pro. When I use this kit for my astrophotography I always tend to have trouble finding what I want to look for. Are there any adapters/attachments so I can put my finderscope/red dot finder on my kit so I can find targets more easily? Cheers William

How to guide with an EQ3 Synscan?
WilliamAstro replied to WilliamAstro's topic in Getting Started General Help and Advice
Anywhere that I want to image, it could be the Orion Nebula, Dumbbell Nebula, or anything like that. -

I am pointing the guidescope directly to where the telescope is pointing to. -
How to guide with an EQ3 Synscan?
WilliamAstro replied to WilliamAstro's topic in Getting Started General Help and Advice
Sorry for not elaborating. Okay so here is the breakdown, I use a Synscan EQ3 for my 72 ED, not a Star Adventurer, The guidescope I use is a ZWO 30mm Mini GuideScope, The guide camera I use is an ASI120MM which is connected to the autoguide port on the motor control via ST4 and connected to my laptop via USB3, I connect my laptop to the USB port on the motor control with a USB port adapter via USB2 so I can also connect my main camera in another port as well. Upon using PHD2, I either have a choice of "on-camera" or "USB" operated with ASCOM. Upon attempting to calibrate, The steps go higher in number and a while later I am met with, "RA Calibration failed". -

I use PHD2 with ASCOM installed, I polar align the mount via polar scope, The mount is connected via USB3 to my laptop using the motor. -

I just thought about acquiring a larger telescope to get closer pictures of the planets, (hence the title) I am looking for a sophisticating size that has great optics and produce great light gathering and detail catching abilities. What is my budget you ask? £1500. It can be a dobsonian, a cassegraine or other type that meets the requirements. Cheers and clear skies William

So I was met with this artefact of this line protruding across the image and especially horizontal lined noise as well. Here are some details to help puzzle what is causing this problem and how to fix this. My single exposure subs are 20 seconds. (lights and darks) 497 lights, 101 darks, 30 or 15 flats, 30 or 15 dark flats, 50-60> bias frames a portion of the lights contained clouds and I took them out of the batch and stacked those and still same thing, used less percentage and still same thing. I used a modified Canon 600D, Star Adventurer 2i Pro, Skywatcher Evostar 72 ED DS Pro with guiding, 2 counterweights for balance. My assumption is that it could be labelled as 'walking noise'. Over the course of capturing the data I needed to reframe the image back to where it had to be as it drifted slowly.
