Hello, This is Nasir Rizwan, a new AAVSO Ambassador from Pakistan. 

I currently have a 4" inch reflector that I'm using for outreaches and currently looking to upgrade to a better telescope. 

What I'm Looking For:

i- Something portable for outreach activities, nothing more than 8" or 10" at the most
ii- A telescope that I could use for Variable star astronomy or something that would help me with research in AAVSO (I'm still figuring out what works for me LOL!)

Daylight observations of Betelgeuse

Hello,

During these days, Betelgeuse is close to the sun. Nevertheless it can be observed using a go-to telescope with a CCD or CMOS camera and a combination of a V filter and a neutral density (ND) filter. The method was described in the JAAVSO Journal of Dec 2021 (https://app.aavso.org/jaavso/article/3798/)

Cleaning dirty sensors and photometric filters

How do you clean the spots from your CCD sensors?  My SBIG ST8 has spots on the sensor, and I've been using Lens Wipes, soft cloth rag for glasses, etc and so far I'm still getting spots on the sensor.  Also my photometric fields still have spots on them.  Any advice on cleaning my CCD sensor lens

 

 

Chat Room

Good morning folks,

I'm writing to let you know that AAVSO has an ongoing "Chat Room" daily at https://kiwiirc.com/nextclient/irc.aavso.org/#aavso

It's just a place to hang out, ask a question of live real people, or just to say hi.

I'm on an hour of two a few days a week. Several others are on virtually all day every day.

Maybe we'll see you there.

Hello Everyone,

I would like to introduce you to our new Instrumentation and Equipment Section Leader, Peter Bealo. Peter has graciously agreed to take on the day to day tasks of the section from Richard Berry, who will still be around, but has found himself busy with AAVSO Board duties. Peter is a long time amateur astronomer and member of the Antique telescope society. He will be a great asset to the section and I hope you will join me in welcoming him.

Thanks,
Bert Pablo

3D Printed Variable Star Decors

Za(Ks)t Wed, 04/20/2022 - 14:23

Hello!
I made a post on Variable Star Astronomy facebook group about my DIY 3D printed variable star decors, and it was suggested to me to post it here :)

Some time ago I 3D printed those variable star decors for my Friends, Adam Nowak (NADA-V120) and Gabriel Murawski (MGAB-V266). Maybe some of you would be interested in such decors? I have no idea how to price it but it's for now: 40 usd + shipping for version with backlight and 25 usd + shipping for version without backlight.

UBVRI photometric filters - I found some!

David Astro (davidastro.com) in Montreal, Quebec, Canada has some Baader filters in stock. I just got my 2" V and also ordered a 1.25" R. Not sure what else is left, but after 3 years of trying to get some filters I ordered them when I saw they were in stock.
