I have a short tube (432mm) ED scope which I occasionally use with a Herschel wedge for white light viewing. I also have a 90mm Mak which I have used with a home made filter for the front as I understand that I can't use the HW with it. Now, would I be better off with a long ish focal length refractor of around 90mm aperture with the Herschel Wedge than the short ED scope with it?? Also. Would a long refractor with the wedge be better than the 90mm Mak with solar filter. ? Asking as i am considering getting rid of the 90 mak as it doesn't get much use anyway and I bought it on a whim tbh. Thanks for any info.

Welcome to SGL. I'm just outside of Swindon myself. 🙂

Sorry I missed this guy's. I was made redundant on Thursday and obviously my head is all over the place at the moment. Apologies again

Considering an Asiair pro with AZGti

Well. Even though I haven't actually used it yet. I decided to re locate the AsiAir to the tripod leg. I feel this will be better weight wise. Just need to manage the cables to the cameras suitably. -
Always liked the sound of this scope. Been waiting a while for it to arrive due to Covid19 disruption. Looking forwards to some darker nights now. :-).

In the past. I have used the RDF to eyeball Polaris through. Prior to using Sharpcap for polar alignment. I assumed this would still be good practice? What's your polar alignment routine like?? Tbh it's not going to save a lot of weight removing it. Lol. -

My "multi finder bracket" arrived today. Oddly it didn't fit the Altair finder base on my scope. So needed a little fettling. Anyway all good now. I have currently mounted everything like this:- I had to use a second counter weight to balance everything. The total weight with the counterweights is approx 4.6kg. I wonder if a longer counterweight shaft could allow me to get away with one counterweight. I will see how it goes and re configure if needed. Perhaps mounting the AsiAir on one of the tripod legs. But that has the issue of having long enough cables as i said previously as more of them will need enough length to allow for movement of the scope. -

That looks and sounds very promising. I am waiting on a dual finder bracket. But I doubt I will get much opportunity to use the set up til the nights start getting a bit longer now. Still, gives me time to familiarise myself with the AsiAir and what my new set up is going to look like. -
Dual finder scope bracket

I looked at that one. But it's OOS. Ordered the one from FLO. Thanks for the info. 🙂 -
Dual finder scope bracket
Bobby1970 replied to Bobby1970's topic in Discussions - Scopes / Whole setups
That looks ideal actually. Must have missed that during my googling. Lol. Many thanks. -
Can anyone point me in the direction of one of these? Want to mount my guidescope and AsiAir on one. Thanks.

Think I will get myself a dual finder bracket. So the guidescope and AsiAir will be on that. Thanks again. -

May I ask, where did you mount your AsiAir?? Have you put it in the finder bracket?? Was a bit concerned about adding more weight and was thinking of attaching it to top of one of the tripod legs. However this would mean multiple cables to cameras etc will need to be long enough to allow for movement of the mount. Whereas if the unit is mounted on the finder bracket there would only be a need for one long cable to power it and allow for movement, the rest of the cables to cameras etc could be shorter? Any suggestions? -

Just had email confirmation that my AsiAir Pro will be delivered tomorrow. Looking forward to it very much. 🙂 -
How do ‘you’ polar align?
Bobby1970 replied to AntHart's topic in Discussions - Scopes / Whole setups
Is this with ASIAIR ?? Cant wait to get mine. 🙂 -
I'm definitely not colour blind. But have worn specs for almost 48 years. And my eyes have got worse over the last few years tbh. For me, CA was never a deal breaker. Yes a semi apo or full apo scope gives better views. More recently I have done very little visual observation. Perhaps some lunar. I'm more into imaging or EEVA nowadays.
-
This was certainly my experience when using the semi apo filter also. I used mine with ST102 and ST120. Maybe this shows how some are bothered more than others by CA???
-
Awesome. Thanks for the help
-
So, do I need to to the calibration every session? Or just if I removed the guidescope and camera?
-
Tried guiding again last night. After a few seconds the graph went crazy like +/- 16. I had removed the guidescope and camera. So I'm guessing this could be part of the issue?? Should I always leave the camera and guidescope attached, once calibration has been performed? Also, if anyone is guiding with an AzGti, is it essential to enable the auxiliary encoder when setting it up prior to guiding it??
-
I seem to recall a Helical focusser when I had the LS35. It's also a rotating one. So it will rotate your camera also. The advice regarding pulling the blocking filter/diagonal out is consistent with my experience with this scope.
-
Can do I guess, but I'm sure it will. Interested in the dimensions of the heatsink and fan tbh.
-
I'd be interested to know which fan, heatsink and peltier unit you used. And where you got it from?? If you don't mind sharing.
